Applications

The pressure gauge type series BH42.. has been especially constructed for the operation with diaphragm seals. A custom bourdon tube that is reduced in volume produces a very slight temperature error only. Diaphragm seals with reduced diaphragm surface areas may also be used. A large selection of diaphragm seals − D5 product category − is available for a large variety of applications.
