Field of application

The Pt100 cable probe is easy to install and provide a high operational safety due to reliable and accurate temperature measurement in common processes. Without additional thermowell the probe sheath is directly in contact with the process medium. This enables the cable probe to detect rapid temperature changes fast and accurate.

The TH12 temperature sensors are RTD's designed for use in the process industry or factory automation type of environment. They are made up of a measurement probe with a RTD, insulation and sheath.

Among other applications the sensors can be used on:

Heat exchangers
Power & recovery areas
Carbon regeneration furnaces
Dryers
Flue gas
Compressor stations
Process reactors

Benefits

High flexibility due to customized immersion length
Fast response time with reduced/tapered tip form
Simplified model structure: Competitively priced, offers great value. Easy to order and reorder
Improved galvanic isolation on most devices (2 kV)
