The 2" or 40 mm SMS diaphragm seal is a screwed type suitable for the food and beverage industries. Diaphragms need to be attached to instrument and filled by Teltherm
The 40 mm SMS male diaphragm composition is available in 316 stainless steel.
Chemical diaphragm seals separate your process fluid from the mechanism of an attached sensing instrument.
The most common applications for using a SMS diaphragm seal are in the food and beverage industries as its rounded threads are easy to clean. Diaphragm chemical seals are also helpful to protect an instrument from high temperature process fluids.
Teltherm offers diaphragm filling on a wide range of gauges and transducers. Please note in order to get the best out of your instrument this process cannot be hurried & larger instruments may need to be evacuated overnight. Any entrapped air in the filling fluid will compromise the behaviour of your system.
