CMR capacitive transmitters Temperature-regulated or temperature-compensated Total pressure measurement CMR capacitive transmitters are the perfect solution for total pressure measurement when the need is for highly accurate measurements that are independent of the type of gas in question. They are suitable for all applications in the pressure range from 1,100 to 1 · 10-5 mbar, and are characterized by their long service life. At the same time, they afford minimum zero drift and outstanding temperature stability. They are non-wearing, resistant to corrosive gases, insensitive to atmospheric...

CMR capacitive transmitters Temperature-regulated or temperature-compensated Operating principle Our transmitters measure the deflection of the diaphragm in form of a change in electrical capacitance detected by the conductors that are vapor-deposited on the ceramic diaphragms. By varying the thicknesses (d) of the diaphragms it is possible to provide measurement ranges from 1,100 to 10-5 mbar. The thinnest diaphragms are barely as thick as a human hair (0.01 mm), and the measured deflections (⌬S) are a mere 0.001 mm. In order to be able to reproducibly measure these small effects, the...
