  • Introduction
  • Specifications
It is a small cartridge-type structure temperature transmitter which converts resistance change from thermocouple emf or thermal resistance into isolated 1～5VDC or 4～20mADC output signal. Transmission output and the corresponding temperature range can be freely changed by display module.
It is an intelligent transmitter which uses microprocessor to do mathematical calculations. It can do high precision linear correction for non-linear input signals.
It equips with HR-WP20SHA display module which can display temperature value directly.
