Ideal Vacuum XactGauge XG-120 Digital Thermocouple Vacuum Gauge Controller System with KF-16 TC Gauge Tube

The Ideal Vacuum XactGauge XG-120 Thermocouple (TC) Gauge Controller is a compact, all-in-one solution that provides low-noise, stable and repeatable roughing and foreline vacuum pressure measurements from 10^-3 Torr to 1.999 Torr (1 to 1,999 mTorr).

The XG-120 controller is housed in a 1/8 DIN enclosure, which can be either panel mounted or located on a bench top. It has tactile front control buttons and a large 6 digit red LED display for easy reading from across a room or in dimly lit locations. The gauge displays in mTorr, µbar and Pa and includes LED indicators for the two set points.

The gauge is equipped with two (Type C) set point relays that can be used to activate valves or to control other external devices. The gauge also has RS232 serial and 5V analog linear outputs for quick integration into a wide variety of systems.

The XG-120 uses inexpensive TC sensors which are used as ‘rough’ indicators to monitor mechanical pump vacuum levels and to signal when crossover (to high-vacuum) pressure has been reached. The controller does not require recalibration when thermocouple gauge tubes are replaced.

The XG-120 controller is available separately for use with your existing thermocouple gauge tubes and includes a power supply, a 10 ft. gauge tube sensor cable (RJ12 to female octal connector) and panel mounting hardware.

Complete systems also include a Teledyne-Hastings DV-6 thermocouple gauge tube with choice of vacuum port (KF-16, KF-25, 1/8” NPT, or 4 VCR).
