Chapter 11 Appendix3-RTD module and PT100 wiring (modul
optional)
11.1. RTD energy meter function
This function is applied to the following meter and measurement temperature
range: D116 Hot(Cold) Energy Meter:0~100
℃
,equipped with PT1000
temperature sensor.
The RTD Module’s main function is to input the temperature values for the energy
measurement. The D116 can automatically calculate the caloric content of water
at different temperatures and deriving an instantaneous energy value and totalized
energy value.
11.2. Wiring (PT1000)
Three-wire connections methods is used for the RTD module and PT1000
temperature sensors,connections methods is as follows.(Note: A1, A2, B1, B2 are
the same color, C1 and C2 are the same color).
The two PT1000 temperature sensors are installed on the inlet and return pipes
and they will input temperature signals to the D116 transmitter.
