Automated calibration practices in process manufacturing

Costs, benefits and feasibility of calibration and documentation for process manufacturing. Process manufacturing plants require hundreds of sophisticated devices that perform countless critical operations ceaselessly, accurately and reliably. Those devices in turn require regular inspection, testing, calibration and repair. Two centuries of industrial experience have established the value of carefully recording the details of those procedures. More than a best practice, businesses and governments often require highly specific recordkeeping to ensure that full value is delivered to customers and that the health and safety of citizens is protected.

However, traditional testing, calibration and documentation practices are also labor-intensive, and with senior operators in scarce supply, downsized teams sometimes choose to defer regular calibration.

This article reviews route-based, automated calibration practices as an alternative to traditional methods. Findings suggest that smaller teams can feasibly conduct and document device calibrations, at a lower overall cost, with additional productivity and operational reliability benefits. It can also include adjusting these devices so that they operate within limits. Calibration is typically performed when installing a new device, changing the settings of an existing device or reinstalling a repaired device.

The devices to be calibrated, often called field instruments, are located on factory floors, atop cooling towers or within pressure vessels — anywhere that process variables such as temperature and pressure need to be known and process control is required.

The most important reason to calibrate is to ensure safety. A tragic example of this necessity was an explosion at a Texas refinery. To perform at the highest efficiency and quality, equipment must be well-maintained and adjusted. Instruments that are not reduce quality and ultimately deduct from the bottom line. In the case of fine chemicals or pharmaceutical products, for example, reduced quality might require the destruction and disposal of an entire batch.

Minor mis-adjustments can have costly consequences. Calibration of the devices that make these custody transfer measurements, especially on pipelines, is one of the most accurate performed in industry. Government regulation and enforcement agencies often require calibration and documentation to verify that devices conform to rules and standards. Many government agencies require timely and documented calibration of both field instruments and final control elements.

For example, the U. International quality standards ISO , and call for detailed calibration procedures to be performed prior to audit approval. ISO and other quality standards typically require that the calibration of the field instrument be checked at regular intervals. In so-called "validated" industries such as the pharmaceutical industry, any changes to a process line, including repair or replacement of a process instrument or a final control element, must be re-validated and traced to documentation before the process line can be put back into service.

Poor calibration documentation can make this validation process time-consuming and expensive and put the manufacturer at risk of fines by the regulating government agency. Calibration and documentation are usually considered expenses, and the higher efficiency resulting from good calibration practices may be hard to distinguish.

Consider, then, the known costs. Primary elements include flow tubes; orifice plates; pressure sensors; wet chemistry sensors such as pH, ORP and conductivity probes; level gauges of all types; and temperature probes. Primary elements are connected to the input of field transmitters. Field transmitters include pressure, temperature and flow devices. They process the signal generated by the primary element, first characterizing it in linear format and applying engineering unit coefficients to it, before then transmitting it in analog usually mA dc or digital format usually some variety of fieldbus.

Note that when a field instrument is manufactured, both the primary element and the transmitter or the actuator, if it is a control valve are calibrated at the factory and the calibration information is supplied with the unit.

This calibration data is often lost. Centralizing calibration information ensures knowledge stays with the facility even as teams change. Analog devices, often called "4 to 20 milliamp loop" devices, were given their name because they transmit a signal that is an electrical "analog" representation of a measured physical quantity such as temperature. They transmit an electric current that is proportional analogous to the magnitude of a measured physical quantity, with 4 milliamps of current representing the minimum scaled value and 20 milliamps representing the maximum scaled value.

This relatively simple technology has low sensitivity to electrical "noise" and has been used for many years. Although many system aspects are now digital, analog devices are still in active use throughout the process manufacturing world.

A magazine survey found that 30 percent of plants surveyed continued to use analog instruments and current loops. Because analog circuits such as current loops drift over time, they require regular calibration. Digital devices convert a measured physical value into a digital signal. A widespread belief holds that fieldbus digital field devices do not require calibration, but this is not true. Although a fieldbus signal provides diagnostic information, it does not provide information about the accuracy of the device, nor does it verify that the device is reporting the process accurately and precisely.

For example, a Foundation fieldbus differential pressure transmitter can report diagnostic information about the transmitter, but it cannot report on the physical condition of the orifice plate across which it is measuring pressure.

Consequently, even if the electronics are operating perfectly, the flow reading transmitted may be inaccurate. Thus, calibration is required even for digital devices.

Fieldbus systems do not have an analog output that technicians can use to verify the accuracy of instrument transmissions to the control system. Without an easily readable output, facilities must either install a readout display at the device or perform calibrations with one technician at the device and the other in the control room.

Both options increase calibration costs. Control valves have actuators that also require calibration to adjust for wear and the effects of stiction. Often these valves must be given a partial stroke test if they have not been actuated regularly.

Calibration is typically performed either where the device is located called in situ calibration, from the Latin term for "in position" or in an instrument shop.

In-shop calibrations are both more thorough and more time consuming. Additional paperwork must be submitted, downtime scheduled, and then the device must be removed, transported, calibrated and then reinstalled. Administrative tasks, such as getting permits or documenting and filing results, can add to the cost and time required to perform even an in situ calibration.

As Ian Verhappen of Industrial Automation Networks and a former chair of the Fieldbus Foundation User Group said, "In many cases getting all the necessary paperwork permits, isolation, etc. Traditionally, documenting a calibration has meant using a log book to handwrite the date and time, the pre-calibration readings, the post-calibration readings and any other observations the technicians made.

Surprisingly, many plants continue to document calibration work by hand. In a magazine survey, 74 percent of respondents said that they were still using pen and paper documentation, which has many shortcomings. First, it both produces and perpetuates errors. The data in handwritten records is often simply illegible or insufficient. Facilities that use a computerized maintenance management system CMMS must then account for the additional time required to manually enter handwritten data, with additional possibilities for error.

Many facilities store field data in more than one database. Calibration data entered in the operations database may not be cross-entered into or accessible by the maintenance database. Several methods are being used to reduce the time and cost of calibration and documentation, including:. From the s to the s, engineering schools graduated large numbers of skilled workers willing to work in manufacturing as operators and technicians. They performed the majority of process calibrations, using the traditional pen and paper methods referenced above.

Starting in the s, however, young people became less interested in manufacturing work, and those employers began having difficulties filling positions. The s brought budget cuts and layoffs. Engineering, maintenance and operations staffs were cut substantially and a new lean manufacturing philosophy took root that continues today, especially in developed economies. It is more common to have many less, and calibration rounds often become an afterthought," a plant engineer said at a recent section meeting of the International Society of Automation.

While those reductions in team size would seem to balance out the decreased workforce supply, another problem has since developed. Smaller teams have less time for mentoring and on-the-job training, to the point where equipment and system-specific knowledge is not being successfully transferred from the individual to the institution.

As older operators and engineers retire, they take their equipment and system knowledge with them. Meanwhile, many facilities still need two technicians for each in situ calibration: one at the transmitter and one at the control system. The Fieldbus Foundation estimates that commissioning requires two techs for a minimum of two hours. Calibration requires similar time and manpower. In the U.

A new generation of "smarter" field calibration tools introduced in the late s began increasing worker productivity by consolidating multiple tools into one and performing functions beyond basic test and measurement, such as assisting with analysis and documentation.

Multifunction documenting process calibrators are handheld, electronic test tools that consolidate multiple calibration steps and functions into a single device, sourcing simulating and measuring pressure, temperature, and a wide variety of electrical and electronic signals. Benefits of this include:. In the words of engineer, columnist and current Fieldbus Foundation User Group chair John Rezabek, "The introduction of documenting calibrators is a chance to revise past practices and maybe switch to calibrate-in-place.

The biggest savings from using a documenting calibrator comes in the route management tool built into the device. Using a single set of permits and paperwork for an entire set of calibrations reduces costs considerably. Unlike paper documentation, calibrator data is never illegible, cryptic or partial. Documenting calibrator data can be directly downloaded into a variety of different CMMS systems with no transcription or filing.

According to Verhappen, automatic documentation commonly reduces errors by 80 to 90 percent. Data downloaded from a documenting process calibrator into a CMMS can even automatically trigger work orders for repair of field devices. Because documenting process calibrators automatically record the as-found and as-left state of each field device in situ and can be operated by a single technician, route-based documenting calibrators can save as much as 50 percent of the time and cost of traditional manual, single-device calibration methods.

Stated differently, the same lean team can accomplish twice as many calibrations in a given period of time. Running a lean team under the traditional operational requirements is a recipe for error. Calibrations simply do not happen the way they should.

Instead of ignoring the looming threat, investigate how existing practices can be made more efficient. Implement route-based calibration, paperless documentation and CMMS data management.

More calibrations will occur more consistently, knowledge will be transferred from the individual to the team and to the institution, and both productivity and quality will increase. Instituting a robust route-based paperless calibration management practice helps mitigate that risk, facilitates knowledge transfer and helps less experienced technicians get up to speed quicker.

Calibrating multiple instruments in the course of a route reduces the cost per calibration, compared to individually calibrating single instruments. Route-based documenting calibrators can save as much as 50 percent of the time and cost of traditional manual, single-device calibration methods.

Good calibration maintenance practices help reduce the probability of such an incident.
