Pressure gauge with diaphragm seal

The TEMPRESS pressure gauge with dia-phragm seal is an ideal solution in situations where the medium is not to come in contact with the instrument´s measuring system whether for reasons of hygiene or due to the thick, crystallising or polluted nature of the medium.

The TR7604 diaphragm seal is a hygienic 1½” clamp(Tri-Clamp®) which fulfils the standard of ISO 2852.

The ultra-thin diaphragm in stainless and acid resistant steel is welded to the top part, allow-ing it considerable freedom of movement. This gives the instrument a high degree of durabi-lity and a level of precision better than ±1% F.S.

Temperature compensated

The unique temperature compensation sy-stem guarantees a correct reading even du-ring extreme variations in the ambient tem-perature.

The system automatically compensates for changes in the ambient temperature of up to 60°C (140°F).

A wide range of other possibilities

The pressure gauge with diaphragm seal is one of more than 150 types TEMPRESS can supply.
