Onsite Instrumentation Calibration Services

Calibration Service

Process Control Services (PCS) has the expertise to calibrate your controllers, recorders, sensor and indicators. Whether it’s from a major manufacturer or an obscure name brand, start-of-the-art or “well used,” our ISA-certified technicians have the depth of knowledge required to test the adjust your instrumentation.

PCS uses test equipment that is certified according to AMS 2750D standards and is NIST traceable. We perform test instrument calibrations in our won ISO/IEC 17025 accredited certification lab.

Onsite calibrations can be performed several ways, depending on whether or not your process is running, and if test probes can be placed adjacent to your temperature sensors. These test are referred to as:

System Accuracy Tests
This preferred test is performed by:

  • Placing a certified test sensor as close to the sensor tip as practical
  • Comparing the reading from the test sensor to the reading of the system

Comparison Tests
If the sensor to be tested is not accessible with your process running, the accuracy of
your instrument reading can then be determined by:

  • Connecting a test instrument to the sensor
  • Comparing the two readings

Multi-Point Calibration Tests
If your process is not running, the instrument can be calibrated at multiple points throughout the operating temperature range per your specification.

We will provide you with the documentation you need to maintain your quality requirements. Our reports are accurate, concise and detailed. The integrity of your calibrations will be clearly reported and the auditing process will be streamlined. All records are backed up on our corporate servers. Calibration due dates are tracked and reminders are automatically sent out.
