Vacuum process controller by DigiVac the Model 801-W2C

The vacuum process controller Model 801-W2C provides vacuum process control by combining fail-safe relays and rugged electronics for system integration and process control. Serves as an upgrade from the Varian 801 pointer meter

  • Very simple and reliable vacuum instrument and process control
  • Most popular for customers building vacuum process control systems
  • Easily panel mountable with a drill bit and hole saw

Model 801-W2C Features:

  • Range: 0.001 – 760 Torr
  • Accuracy Specifications:
  • 0 to 0.009 Torr +/-0.002 Torr0.010 – 2.00 Torr +/-10% of reading2.00 Torr to 5 Torr  +/- 1 Torr

    Above 5 Torr – continuous and monotonic (increasing reading indicates increasing pressure)

  • Robust fail-safe relay controls-gives the ability to control an external device via
    2 SPDT external connections at user specified set-points
  • Pre-calibrated and tested against a NIST standard with Agilent 531 Thermocouple Sensor
  • Note: NIST certification included with the gauge is an available option to add to your order
  • CE Certified
  • Panel Mount

The vacuum gauge is highly resistant to shock because it has no moving parts, thus requiring infrequent calibration. The gauge controller has a large bright LED display which can be easily read from across the room, or in dimly lit locations.

The Model 801W series of panel mount vacuum gauges are a drop in replacement for the Varian 801 and other Hastings and Fredericks gauge controllers which mount in the industry standard 3 bolt pattern.

Each vacuum gauge includes:
• A vacuum gauge controller
• A thermocouple vacuum gauge tube (vacuum sensor)
• A cable to connect the vacuum gauge controller to the thermocouple vacuum gauge tube
• An AC adapter that runs on 100-230VAC, 50/60 Hz with line cord adapter

Applications: medium vacuum applications, industrial furnaces, gas reclamation, and vacuum process control applications
