Series 8423 - Resistance Thermometer
Welded、Sensor element replaceable
 
 
Description
Series 8423 resistance thermometer is suitable for containers and pipes. The process connection is welding.

This series of resistance thermometer is suitable for liquid and gaseous media under medium mechanical load. The thermowell adopts the form of integral drilling and is connected with the junction box through thread.

The replaceable measuring element does not need to take out the thermometer completely during the replacement process. Therefore, inspection and replacement can be carried out during equipment operation or when replacement maintenance is required during operation. Selecting the standard probe rod length can shorten the delivery time and reduce the inventory of spare parts.

The resistance thermometer can be equipped with its own temperature transmitter.
