Description

Application


The TH55 Modular TC thermometer is designed for demanding environments, such as those found in power plants, refineries, and the chemical or petrochemical industries. Built to be durable, this thermometer integrates seamlessly with existing thermowells. When paired with a variety of head transmitters, it forms a complete, ready-to-use unit that offers enhanced measurement accuracy and reliability.

These thermocouple assemblies are specifically designed for use across a range of process industries, including heavy industrial settings. Each assembly comprises a magnesium oxide-insulated thermocouple as the sensing element, housed within a robust thermowell made from barstock material.

Industries where this thermometer can be applied include:

  • Chemical industries
  • Petrochemical industries
  • Power generation facilities
  • Refineries
  • Offshore platforms

 

 


 

Benefits


A comprehensive solution for temperature measurement needs, the TH55 offers world-class transmitters integrated with sensors, making it ideal for heavy process industry applications.

  • Ready for immediate use—easy installation straight out of the box!
  • Improved galvanic isolation on most models (up to 2 kV).
  • Simplified model structure, providing a competitively priced option that offers excellent value. Ordering and reordering is straightforward, with a single model number encompassing the sensor, thermowell, and transmitter assembly for a complete solution.
  • All iTEMP® transmitters ensure long-term stability, with a drift rate of less than 0.05% per year.
