CMX1T25PN2X is a Brooks Instrument XacTorr CMX Series heated digital capacitance manometer identifier observed in stored auction records. The reliable model-code elements identify it as a CMX capacitance manometer, CMX45 heated-temperature variant, and T25 500 Torr full-scale pressure range. The remaining suffix characters should be verified against the physical label or order record before assigning connector, fitting, relay, calibration-orientation, or compliance details
Configurations vary. Verify the exact unit before choosing a replacement.
The PN2X suffix is retained as part of the exact identifier, but connector, fitting, relay, calibration, and compliance details should be confirmed from the nameplate or order record
Pressure
Observed full-scale range
500 Torr full-scale range is supported by the T25 model-code element and stored auction title evidence
CMX family full-scale ranges
0.1, 0.2, 0.5, 1, 2, 5, 7.5, 10, 20, 50, 100, 200, 300, 500, and 1000 Torr; pascal-equivalent ranges are also available
Measurement type
Total pressure measurement by capacitance diaphragm sensing, independent of gas composition
Performance
CMX45 accuracy
+/-0.15% of reading from 10% of full scale to full scale, including hysteresis, linearity, and repeatability within the calibrated range at 21 degrees C; reference uncertainty excluded
Pressure response time
40 milliseconds
Zero temperature coefficient
0.002% full scale per degree C for heated 45, 100, and 160 degrees C variants
Span temperature coefficient
0.02% of reading per degree C
Warm-up time
2 hours for most ranges; 4 hours for full-scale ranges of 1 Torr or lower
Sensor
Sensor design
Patented Mark IV sensor design intended to improve stability and protect against process-gas deposition
Temperature control
Dual-zone temperature control for fast warm-up, precise temperature control, and rapid response to changes
Zero adjustment
Intelli-Touch zero adjustment with local push-button and remote zeroing; zeroing is inhibited if pressure is too high or the device is not warmed up
Ratings
CMX45 ambient operating temperature
15 to 35 degrees C
Over-pressure limit
17 psia or 125% of full scale, whichever is greater
Materials
Wetted materials

Electrical
Analog output
0-10 Vdc analog pressure output, 5 kOhm load
Analog connector options
9-pin male D-sub or 15-pin male D-sub depending on configured model
Diagnostic interface
2.5 mm RS-485 diagnostic port
Digital interface option
DeviceNet option with 5-pin Eurofast connector and ODVA/SEMI SIG vacuum gauge profile support on DeviceNet models
CMX45 power requirement
