IFM E30403 is a welding thermowell designed for compatible TA-series temperature sensors in hygienic and demanding process applications. It protects the temperature sensor from direct exposure to process media while providing a robust process connection. The unit is designed for TA343x, TAA431 and TAD191 temperature sensors and features a 126.5 mm probe length. Its stainless-steel 316L/1.4404 construction provides durability and resistance to demanding process conditions. The thermowell has a 35 mm welding/process connection arrangement and a G 1/2 sealing-cone sensor connection. It is designed for applications where reliable temperature sensing and hygienic process integration are required.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The E30403 is designed for hygienic process applications where sensor installation must support cleanable and reliable equipment. Its stainless-steel construction and smooth wetted surface support hygienic installation requirements. The thermowell separates the temperature sensor from direct contact with the process medium. This can help protect the sensor while allowing accurate temperature measurement. It is suitable for food, beverage and other process industries where hygiene and material compatibility are important.
A thermowell protects the temperature sensor against pressure, flow, mechanical impact and aggressive process media. E30403 provides a long 126.5 mm probe length for applications requiring deeper temperature insertion. The robust stainless-steel design helps extend the useful service life of the installed temperature sensor. The sensor can also be removed or serviced without directly exposing the sensing element to the process when the installation is correctly designed.
The welding design allows the thermowell to become an integrated part of compatible process equipment. The unit uses a G 1/2 sealing-cone connection for the temperature sensor and a Ø35 mm process-side design. Its surface finish is specified at less than 0.6 µm Ra for the wetted surface. This makes it suitable for applications requiring a hygienic, robust and cleanable process connection.
