ACTIVELINE CMR capacitive transmitters Temperature-regulated or temperature-compensated

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...

Measurement independent of gas type Sensor in ceramic technology – Maximum temperature stability – Resistant to corrosive gases – Outstanding service life Simple operation – Pushbutton zeroing – 0-10 V output signal with integral error signal Compatible with the Pfeiffer Vacuum ActiveLine series Sensor

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...

Operating principle Ceramic Sensor Sensor Shield Vacuum Connection In Pfeiffer Vacuum transmitters, the electronics and sensor form a compact unit A sensor shield safeguards against contamination and increases service life Reference Chamber Measurement Chamber The sensor consists of 3 basic components, which are all of ceramic design Together with the diaphragm, the upper section forms the reference chamber The pressure in the reference chamber is much lower than the vacuum to be measured The ceramic is coated on the reference chamber side, and curvature of the diaphragm caused by the...
