Omnigrad T TST310 - RTD Thermometer, Cable Probe
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.
