Description

Application

The highly modular TH11 thermometer is versatile and suitable for a wide range of industrial applications. It is commonly used in heat exchangers, dryers, process reactors, reactor stations, and more. When paired with various head transmitters, it forms a fully functional unit that enhances measurement accuracy and reliability. The design allows for rapid response times by enabling direct contact measurement without the need for a thermowell. Additionally, the availability of multiple process connections and dimension options ensures flexible application possibilities.

The TH11 temperature sensors are RTDs specifically designed for use in the process industry and factory automation environments. Each sensor consists of a measurement probe with an RTD, insulation, and a protective sheath.

These sensors are applicable in various scenarios, including:

  • Heat exchangers
  • Power and recovery areas
  • Carbon regeneration furnaces
  • Dryers
  • Flue gas systems
  • Compressor stations
  • Process reactors

 


Benefits

The modular design offers high flexibility, with standard terminal heads and customizable immersion lengths to suit diverse needs.

Our temperature measurement solutions provide a comprehensive, one-stop-shop experience. The world-class transmitter, integrated with the sensor, is ideal for demanding process industry applications, and it’s ready for immediate use right out of the box.

Most devices feature enhanced galvanic isolation up to 2 kV.

The simplified model structure ensures competitive pricing and excellent value, making it easy to order and reorder. A single model number includes both the sensor and transmitter assembly, providing a complete point solution.

All iTEMP® transmitters guarantee long-term stability with an accuracy of ≤ 0.05% per year.

The design includes a fast response time due to the reduced or tapered tip form.

Selecting a head or field transmitter is straightforward, with options including Analog output (4 to 20 mA), HART®, PROFIBUS® PA, or FOUNDATION Fieldbus™.
