  depends on process connection

This device is a metallic protection tube with threaded or flanged welded process connection. Thermometer connection is a NPT female thread. A wide range of flange sizes according to common standards and materials for this device is available. Ideally, this leads to a wide range of flexible installations in heavy duty applications.

TA540 is designed for use with resistance and thermocouple thermometers in heavy duty applications.

• The stem shape can be straight or stepped for fast response time

• A wide choice of pipe sizes, materials and process connections is available

• TA540 is an industry standard protection tube manufactured from pipe

• Extension, immersion length and total length can be chosen according to process requirements

• The process connection can either be threaded or flanged weld

• Special versions can be manufactured according to specifications

• The connection to the thermometer is a female thread
