DATA SHEET Vaccuum Capacitance Manometers XacTorr ® Digital Capacitance Manometer Rugged, Stable Digital Capacitance Manometers for Process Vacuum Measurement Brooks XacTorr® CMX Series digital vacuum capacitance manometers (also referred to as capacitance diaphragm gauges) incorporate industry-leading features that improve measurement reliability, minimize drift, resist diaphragm contamination, and minimize thermal effects. The result is an exceptionally reliable capacitance manometer family for all vacuum measurement applications. An important benefit of the XacTorr® vacuum capacitance manometer is its advanced Mark-IV sensor. The sensor chamber contains surface areas that are not used in the pressure measurement; these surfaces provide locations for particles and condensable vapors to accumulate without affecting the sensor, dramatically reducing the need for re-zeroing and greatly extending sensor life. The sensor diaphragm is made from corrosion resistant Inconel®. Because they are fully digital devices, XacTorr® vacuum capacitance manometers operate over a wide dynamic range with extremely good accuracy. Flexible digital signal processor based electronics eliminates manual potentiometers and drift associated with the aging of old-style analog electronics. Digital precision: • Multi-decade digital calibration provides superior window of “known accuracy” • Real-time compensation for ambient temperature variations which improves measurement repeatability • lntelligent zero adjustment, local push-button, and remote zeroing for ease of maintenance capability that also improves long-term repeatability lntelli-Touch zeroing ensures that the XacTorr® Series cannot be zeroed if the pressure is too high or if the capacitance manometer has not reached a stabilized operating temperature - a common operator error with analog capacitance manometers. Highly efficient dual-zone temperature control: • Real-time temperature control of the sensor for improved measurement stability & repeatability • Fast warm-up with intuitive temperature status LED • Rapid response to changing system conditions View XacTorr® CMX Series Product Page
