UHV NGC3 Pressure Gauge Controller & Gauges etc.

Active Gauge Inpout – Industry standard RJ45 jack for connection of most low power (24 V, 1 W max.) active gauge heads. Selectable linear or log formats.Ideally suited for use with our APG Active Pirani gauge head.
Ion Gauge Operation – Four modes of operation; Auto and Interlock use Active or Pirani gauge pressure to automatically start/stop the Ion gauge, or prevent it from starting based on Active or Pirani gauge pressure.External inhibit allows start/stop of Ion gauge from an externally supplied logic signal.Use manual mode to force Ion gauge on and off as required.
Serial Interface – Read back pressure measurements or control the NGC3 via the easy to use serial interface. Full documentation of the protocol is provided, making it easy to integrate into your application.Software is available for download on our website which demonstrates the interface features offered by the NGC3

Controller Features:
1200 mbar to 3×10-11mbar continuous measurement range.
Controls 2 ion gauges sequentially, 1 active gauge and 2 AML legacy pirani gauges.
Bright green LED display; measurements are easy to read. Assignable custom gauge labels.
Multiple Ion gauge modes, including start/stop and interlock based on Active or Pirani gauge pressure.
1U high full-width for easy rack-mounting.
Display pressure in mBar, Torr or Pascal, or Ion current in Amps.
Password protection feature; prevent inadvertent changes to important setup.
Automatic or manual emission current setting; sensitivity adjustable 1 mBar-1to 140 mBar-1.
Manual and automatic electron-bombardment degas programs.
4 power relays for process control.
System bake-out program with control of temperature, time and over-pressure limit. Integral K-thermocouple amplifier.
RS-232C interface for data-logging and control, 1.0 volt/decade Recorder output.
Operates from 100 V to 240 V, 48 to 65 Hz supply without adjustment

 

Specifications:
Controller
Pressure Display : Scientific notation (1 or 2 decimal place resolution) or bar graph displays in mbar, Torr or Pascal.
Supply Voltage : 100V to 240V nominal at 48 to 65Hz, without adjustment.

Current Display : Whole values in pA, nA, µA and mA.
Operating Temperature : 5°C to 35°C for specified performance. Incoming air temperature is measured and displayed and operation is inhibited at >40°C.
Power Consumption : <20 Watts idling, <75 Watts in emission.


Ionization Gauge
Gauge Type
PM-AIG1xG is recommended. Bayard-Alpert gauges with coiled filaments from many other manufacturers are suitable without adjustment other than sensitivity.
Range
From 1 x 10-3to below 3 x 10-11mBar with a UHV gaugehead with tungsten filaments. The lower limit is dependent on gaugehead, cable construction, cable length and conditions of use. The upper limit is determined by the acceptable life of the filament and my be extended by the use of thoria or yttria-coated iridium filaments.
Accuracy & Repeatability
Determined principally by the gaugehead: controller errors are much smaller. Emission at 0.5mA is recommended.
Electrometer Logarithmic Conformance
Range                   21°C      5°C to 35°C
1 mA to 350 pA      <1%          <1%
<350 pA to 10 pA   <1%          <4%
<10 pA to 2 pA       <10%        <20%

Gauge Supplies
Grid: +200 V in emission, +500 V at ≤60 mA in degas. Filament: +50 V bias, ≤12 V at ≤4.2 A (Tungsten), ≤2.6 A (Iridium) with power limited to 30 W maximum.
Pirani Gauge
Gauge Type
PM-PVU2 and PM-PVB2.
A constant-voltage bridge circuit reduces contamination at high pressures. AML Pirani gaugeheads may be exchanged or extension leads may be connected without adjustments being necessa.
Active Gauge
Self-powered or Active Gauge with +10 V full-scale output. Format selectable between linear (1, 10, 100, 1000 mBar or Torr full scale) or log (1 V/decade, 0.5 V at 1 x 10-6mBar). The instrument provides a regulated +24 Vdc supply, 1 W maximum, protected by a 50 mA self-resetting fuse to power a connected Active gauge.
