Omnigrad T TST310 RTD thermometer, cable probe

Omnigrad T TST310 RTD thermometer, cable probe

 

Cost efficient RTD sensor for use in many process and laboratory applications

 

Product Overview

 


The RTD cable probe is easy to install and provide a high operational safety due to reliable and accurate temperature measurement in common processes. The probe is specially suited to temperature measurement in machinery, laboratory equipment and plants in gaseous or liquid medium like air, water, oil, etc. 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.

Benefits

  • High flexibility through user-specific insertion lengths and variable process connections

  • Fast response time

  • Single or double Pt100 sensor of accuracy class A, B, or AA as per IEC 60751

  • Types of protection for use in hazardous locations: Intrinsic safety (Ex ia) and non-sparking (Ex nA)

Field of application

The resistance thermometer is specially suited to temperature measurement in machinery, laboratory equipment and plants in gaseous or liquid media like air, water, oil and others.
