Can Your Digital Pyrometer Gauges Be Tuned or Recalibrated in the Field?

Yes—The Sensor Connection’s digital pyrometer gauges are designed with field adjustability in mind. While our gauges are factory-calibrated for accuracy out of the box, many models include user-accessible tuning features that allow for recalibration or fine adjustment when necessary.

When Would You Need to Recalibrate?

Field recalibration is not typically required under normal use, but you may want to adjust your gauge if:

  • You’ve replaced the thermocouple sensor and notice a slight reading offset
     
  • You’re integrating the gauge with a new or non-standard sensor
     
  • You’re troubleshooting inconsistent or unexpected temperature readings
     
  • You need to match readings with a reference device for precision tuning

How Field Calibration Works

Most of our digital pyrometers include an adjustment method (varies by model):

  • Zero and Span Pots: Some models feature trim pots accessible from the gauge housing for adjusting zero offset and full-scale span.
     
  • Push-Button Programming or Digital Menus: Higher-end models may allow calibration through on-screen menus or button combinations.
     
  • Reference Temperature Comparison: Recalibration should always be performed using a known, stable temperature source for comparison, such as a temperature bath or industrial reference probe.
     

Note: Calibration should only be performed by qualified personnel or under guidance from our technical support team to avoid affecting performance.

Important Tips for Recalibration

  • Always use the correct thermocouple type (e.g., Type K or J) as specified for the gauge.
     
  • Allow the sensor and gauge to stabilize at the calibration temperature before making adjustments.
     
  • Avoid recalibrating based on transient conditions (e.g., fluctuating engine temps).
     
  • Document calibration settings for consistency and traceability.

     

What if Field Recalibration Doesn’t Fix the Issue?

If recalibration doesn't resolve the problem, the cause may be:

  • Sensor degradation or damage
     
  • Signal wiring issues or poor connections
     
  • Interference or grounding problems
     
  • Gauge internal fault (rare)
     

We recommend contacting our support team for diagnostics and further assistance.

Summary
 

  • Yes, most of our digital pyrometers can be tuned or recalibrated in the field.
     
  • Recalibration is useful when changing sensors or correcting minor offsets.
     
  • Always compare readings to a known temperature reference.
     
  • Follow proper procedures or consult support for best results.
