Siemens SITRANS T Series - Transmitter Sensor Matching; Introduction

Result
The device calibrates to your measured values.
The device moves the characteristic by the di󹪜erence between the original and the new
calibration points.

9.4.6 Transmitter sensor matching
9.4.6.1 Introduction
The Callendar-Van Dusen coe󹪟cients are used to match the temperature transmitter with the
sensor. If requested, the sensor manufacturer will provide you with the Callendar-Van Dusen
coe󹪟cients according to IEC 60751 with the sensor. The results are correctly measured
measured values over the desired temperature range through very good approximation of the
actual temperature response of the platinum resistance thermometer.
You can change the calibration points R0, A, B, C, Alpha, Beta and Delta using the remote
operation.
