Product Description


Active Gauge Vacuum Transmitter | No-Tools Required To Replace Sensor


  • Active Gauge—vacuum transmitter measures full range of rough vacuum pinpointing either gross or fine process errors or leaks |Measures from 1 micron to 760,000 microns (760 Torr) or atmosphere| Includes RS232 and  5 Volt analog output
  •  Efficient—designed with no moving parts for durability and reliability/ No  mounting is required
  •  Replaceable sensor—field-replaceable allowing for longer transmitter life
  •  Calibrated—Every Model 22W is calibrated and pretested under actual vacuum against a NIST standard
  •  Applications—freeze dryers, refrigeration systems assembly lines, vacuum ovens, laboratory, and foreline gauge solution


Model 22W has a compact electronic package that fits right on top of the vacuum tube


There is no need to take up valuable benchtop or panel space!


Simple Set-Up of Vacuum Process Telemetry:

  • Plumb the vacuum gauge tube into your vessel
  • Plug in the Model 22W active gauge on top of the gauge tube
  • Run the low voltage power wire (provided) to the gauge
  • Connect the digital signals


Options:     536/CE rated tube     |     Measurement Units


RS232 output: can be used to graph and plot historical data with the DigiVac plotting software, and as a vacuum transmitter to a PLC or other device.
