NMT539 Ex d [ia] and TMD1 Ex d combination
Average temperature device NMT539 can be connected to Transmitter TMD1 or Servo
Level Gauge TGM5 via local HART (Ex d) communication. Because local HART
communication is digital, it is able to send a larger volume of information compared to the
conventional RTD method. This means that NMT539 can work with not just DRM9700 but
also with NRF560. If NMT539 WB probe and NRF560 are used together, confirm that the
supply voltage to TMD1 is stable at 100 VAC or higher.
