Head Mounted Temperature Transmitters Introduction

Head mount temperature transmitter receive the signal from the resistance temperature detector (RTD) or Thermocouple (TC), and converts the measured temperature signal into 2 wire loop powered 4 to 20 mA equivalent signal.

The head mount transmitter is a universal temperature transmitter and it has many advantages over a conventional temperature transmitter. The head temperature transmitter have a HART communication protocol , and the transmitter parameters like temperature range, type of temperature sensor and other parameters can be remotely programmed.


Head Mounted Temperature Transmitters Feature

The salient features of Head Mount Temperature Transmitter are as follows.

  1. It accepts Pt-100 input and Types J/K/T/E/R/S/B/N Thermocouples.

  2. User can configure the transmitter with PC software

  3. Universal setting with HART protocol for various input signal.

  4. It has galvanic and optical isolation and hence signal to noise ratio is more, and loop grounding problem gets eliminated.

  5. It has non-volatile memory with data logging

  6. It has internal temperature sensor for active temperature compensation

  7. Higher measuring accuracy resulting from decreased cable length from sensor to transmitter.

  8. No compensating cable required with use of thermocouples

  9. Easy replacement of the sensor and transmitter.

  10. Easy programming of various input signals

  11. Built-in cold junction compensation

  12. Low signal to noise ratio

  13. Reduced cabling

  14. Remote programming and calibration

  15. Low cost
