HTM208 explosion-proof digital temperature transmitter utilizes PT100 as the signal measurement element. The amplification circuit is enclosed in a stainless-steel casing to transform the sensor signal into a standardized output. Thorough testing and aging of all components, as well as semi-finished and finished products, have been conducted on this entire device. Due to its exceptional reliability, extensive adaptability, and various product options, it finds extensive application in on-site temperature measurement and control within industrial processes such as petroleum, chemical industry, metallurgy, electric power, hydrology, and more.


On-site temperature measurement and control are crucial in various industries, including:

  • petroleum

  • chemical industry

  • metallurgy

  • electric power

  • hydrology, etc.


  • On-site display

  • Support RS485 communication protocol or HART communication protocol

  • Shell protection grade IP65

  • The material in contacted with medium is stainless steel with good corrosion resistance.

  • Suitable for temperature measurement of fluid media, long-term stable operation

  • Impact resistance, vibration resistance and corrosion resistance
