Material certificate per EN 10204-3.1.
Thermowell with reduced tip and electropolishing of wetted parts available.
Base can be filled with heat sink compound.

Technical Data

Temperature sensor details are available in Type series GA2730, data sheet T4-017.
Response time varies based on thermowell design and use of heat sink compound, ranging from t90 = 4 s to t90 = 15 s.

Design and Dimensions

Designs available with field housing and circular connector.
Insertion length calculation varies based on connector type.

Order Details

Thermowells are available in various configurations, including different surface roughness standards, instrument connections, and process connections.
Order codes specify thermowell diameter, insertion length, and material.
Additional features such as material certificates and electropolishing can be specified.

Critical Information

EHEDG certification is contingent on the use of specific gaskets and hygienic design options.
