| Description |
Series 8424 resistance thermometer is suitable for containers and pipes. DIN EN 1092-1 standard flange is available.
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. Thermowells made of stainless steel shall be used under normal chemical conditions.
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 insertion depth, flange size, design of thermowell, junction box and sensor can be selected to meet different application needs.
The resistance thermometer can be equipped with its own temperature transmitter. |
