XacTorr® Heated Capacitance Manometers

By Brooks Instrument

MODELS: CMX0 / CMX1 / CMX2 / CMX3 Minimize drift and thermal effects. Maximize vacuum process results. Maximize the efficiency and performance of your vacuum-dependent processes: Choose XacTorr® Series digital vacuum capacitance manometers from Brooks Instrument. XacTorr® Series devices incorporate industry-leading features that improve measurement reliability, minimize drift, resist diaphragm contamination and minimize thermal effects. The advanced Mark-IV sensor contains surface areas not used in pressure measurement – providing locations for particles and condensable vapors to accumulate. This reduces the need to re-zero the gauge and increases sensor life without risking sensor drift. Additionally, an optional fast response sensor is available for superior closed loop control performance. The result: ultra-accurate, repeatable and efficient vacuum measurement that ensures each time you evacuate a chamber, it reaches the precise Torr your process requires for clean, contaminant-free production. Features - Available for process ranges from 0.10 Torr to 1000 Torr - Multiple accuracy levels available - Patented Mark IV sensor - Digital architecture enables operation over a wide dynamic range with extremely good accuracy - Dual-zone temperature control improves measurement stability and repeatability - Multi-decade digital calibration provides superior window of known accuracy - Intelli-touch zero adjustment - Independent & easily accessible diagnostic service port - DeviceNet® and analog communication options Benefits - Lower drift, superior protection from deposition of process gases - Elimination of manual potentiometers and drift associated with electronics - Fast warm-up, close temperature control, rapid response to changes - Multi-decade calibration provides superior window of known accuracy, real-time compensation of ambient temperature effects - Cannot be zeroed if pressure is too high or desired temperature not reached - Diagnostic port allows monitoring and data acquisition simultaneously with device operation for chamber and tool matching along with “real time” advanced troubleshooting Pressure Range: 0.1, 1, 2, 10, 20, 100, 1000 Torr (mBar & Pascal References Available) Accuracy: CMX0: 0.25% of Reading, CMX1, CMX2: 1 to 1000 Torr Ranges = 0.15% of Reading, CM1, CMX2: < 1 Torr Ranges = 0.25% of Reading Connectivity: DeviceNet, RS485 Device Temperature: CMX0 Ambient, CMX1 45°C, CMX2 100°C, CMX3 160°C Measuring Principle: Capacitance Diaphragm Gauge
