What are the calibration tolerances for Pressure Switch /Temperature Switch /Level Switch?


Calibration tolerances are based on process requirements and do not use manufacture accuracy specification.

Pressure Switch Calibration Tolerances -

-Generally +/- 1 psig for pressure switch with setpoint < 100 psig
-Wider tolerance ok depending on purpose
-Tolerance N/A for reset point unless critical to process.

Temperature Switch

-Generally +/- 1 deg C is for RTD input. 2 deg C for thermocouple input.Wider for filled bulb and extreme temperatures if process requirement allows.

Level switch

  • +/- 1 inch

Flow Switches

+/-5 %
