A separate test procedure for pressure transmitters
IEC 62828-2:2026 supplements the general part with procedures specific to pressure transmitters — the most frequently calibrated group of process instruments.
- Pressure is measured in almost every industrial installation, and pressure transmitters are the largest group of instruments submitted for calibration.
- Part 2 describes tests specific to this quantity: the influence of temperature, overload, long-term stability and mounting position.
- The document is written for manufacturers and testing laboratories, yet it shapes what a calibration laboratory finds in the technical data of an instrument.
- Parts 1 and 2 together allow instruments from different makers to be compared under identical conditions — a precondition for a fair choice of equipment.
