Process resistance thermometer
Description
Resistance thermometers in this series can be combined with a large number of thermowell designs. The replaceable, centrically spring-loaded measuring insert and its extended spring travel enable combination with the widest range of connection head designs.
A wide variety of possible combinations of sensor, connection head, insertion length, neck length, connection to thermowell etc. are available for the thermometers; suitable for any thermowell dimension and any application.
Operation without thermowell is only recommended in certain applications.
