Specific linearization and sensor matching
Selecting the sensor types 'Callendar-van-Dusen' or 'Polynomial RTD' improves the accuracy of the system or defines user-specific linearisation of resistance
thermometers. A detailed description of the 'Callendar-van-Dusen' method and 'Polynomial RTD' linearisation is provided in the Appendix to these Operating
Instructions.
The selection list of the sensor type is displayed depending on the PV unit. Example: When
selecting a resistance thermometer the PV unit must first be set to
Ω.
Sensor connection
Input of RTD connection mode.
Input:
• 2-wire
• 3-wire
• 4-wire
Function is only active on selection of a resistance thermometers (RTD) in the device
function SENSOR TYPE.
+
+
Cold junction
Selection of the internal (Pt100) or an external comparison
measurement point.
Input:
• internal
• external
Function is only active on selection of a thermo-couple (TC) in the device function SENSOR
TYPE.
+
+
External
temperature
Input of the external comparison point measurement value.
Input: -40.00 to 85.00 °C (°C, °F, K)
0 °C
Function is only active when "external" has been selected in the device function COLD
JUNCTION.
+
+
2-wire
compensation
Input of cable resistance compensation on a 2-wire RTD connection.
Input: 0.00 to 30.00
Ω
Function is only active when a 2-wire connection has been selected in the device function
SENSOR CONNECTION.
