CMX1T25PN2X

Brooks Instrument XacTorr CMX45 500 Torr Capacitance Manometer

About this part

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.

Specifications

Identification
Device typeHeated digital vacuum capacitance manometer, also called a capacitance diaphragm gauge
Series familyBrooks XacTorr CMX Series
Reliable decoded model codeCMX = capacitance manometer; CMX1 = CMX45 heated model; T25 = 500 Torr full-scale pressure range
Unverified suffix boundaryThe 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 range500 Torr full-scale range is supported by the T25 model-code element and stored auction title evidence
CMX family full-scale ranges0.1, 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 typeTotal 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 time40 milliseconds
Zero temperature coefficient0.002% full scale per degree C for heated 45, 100, and 160 degrees C variants
Span temperature coefficient0.02% of reading per degree C
Warm-up time2 hours for most ranges; 4 hours for full-scale ranges of 1 Torr or lower
Sensor
Sensor designPatented Mark IV sensor design intended to improve stability and protect against process-gas deposition
Temperature controlDual-zone temperature control for fast warm-up, precise temperature control, and rapid response to changes
Zero adjustmentIntelli-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 temperature15 to 35 degrees C
Over-pressure limit17 psia or 125% of full scale, whichever is greater
Materials
Wetted materialsInconel and/or AISI 316L stainless steel
Electrical
Analog output0-10 Vdc analog pressure output, 5 kOhm load
Analog connector options9-pin male D-sub or 15-pin male D-sub depending on configured model
Diagnostic interface2.5 mm RS-485 diagnostic port
Digital interface optionDeviceNet option with 5-pin Eurofast connector and ODVA/SEMI SIG vacuum gauge profile support on DeviceNet models
CMX45 power requirement+24 Vdc +/-10% at 400 mA, or +/-15 Vdc at 300 mA
Connections
CMX family fitting options0.50 in OD tube stub, KF-10 flange, KF-16 flange, KF-25 flange, 8 VCR 1/2 in female, Mini CF, and 4 VCR 1/4 in female options are listed in the CMX model-code table
Controls
Digital functions on DeviceNet modelsRead pressure, set zero, reset factory defaults, report run time, and change device address and baud rate
DeviceNet data-rate options125, 250, and 500 kbps with network lengths of 500 m, 250 m, and 100 m respectively
Compliance
EMC compliance contextBrooks CMX data sheet lists 2014/30/EU EMC Directive EN 61326-1:2013
Environmental compliance contextBrooks CMX data sheet lists RoHS 2011/65/EU and 2015/863/EU plus REACH EC 1907/2006
Applications
Application domainProcess vacuum measurement for semiconductor tools, thin-film processes, vacuum chambers, and other applications requiring stable gas-independent pressure measurement
