Diaphragm Manometer PC 100/160 Hengesbach

Hengesbach is a company from Deutschland. For more than 50 years Hengesbach develops, manufactures and distributes innovative measuring technology for applications in production processes where functionality, reliability and accuracy of the instruments are of highest priority even under extreme process conditions.

Diaphragm Manometer PC 100/160

Diaphragm manometers PC 100/160  with horizontal measuring flanges for chemical applications are suitable for measuring thin liquids (threaded connection G ½ B) and especially contaminated and highly viscous media (e.g. open connection flange) in over- and under pressure ranges from -1 to 0 bar and 0/0.6 – 25 bar.

The devices are made from solid stainless steel and are suitable for challenging environments and media. They are highly shock-resistant and have a high level of over pressure protection. When the device is used in a shock-prone environment, the glycerine filling acts as a shock absorber for all components. Electrical contacts have been provided for the alarm and switch functions.
