Diaphragm pressure gauges

Diaphragm pressure gauges are having a measuring principle based on a diaphragm. Both BDT12 and BDT13 are based on this principle. BDT13 is specifically for measuring differential pressure gauges where the BDT12 is only measuring gauge pressures.

Where pressures are too low for the bourdon tube principle (<600 mbar) the diaphragm principles are very reliable and stable.

Pressure gauge assemblies

Most pressure gauges are mounted in combination with an accessory. Each accessory has its own function such as blocking the main process line towards the pressure instrument, an syphon for condensation of steam application, or overpressure protecting devices such as the BDT49. Badotherm has a lot of experience with all instruments and accessories and knows when and how the accessories should be used. Badotherm factories and test facilities are equipped with all assembly and test devices to mount and test the assemblies to the required standards. Leak testing and pressure testing are just two of the common test that are standard on assemblies made by Badotherm.
