Technical Specs

UHV Pressure Gauge Controller & Gauges etc.

Controller Features:
 1000 mbar to 3×10-11mbar range.
Controls 2 ion gauges sequentially, 2 pirani gauges and 1 capacitance manometer.
Bright green LED display shows bar graph or numeric pressure, trend, diagnostics etc..
Display in mbar, Torr or Pascal. Permanent bar graph of Pirani pressures.
Simple, guided setup is re-entrant and can be password protected.
Reduced emission current. Instrument can advise optimum current or may be set
manually. Variable ion gauge sensitivity. Filament in use selectable from front panel.
Automatic start of ion gauge in pump-down and can be interlocked by Pirani or external signal.
Manual and automatic electron-bombardment degas programs.
Integral, variable sensitivity leak detector with audio output on Pirani 1 or ion gauge.
4 power relays for process control (5A, 240V) flexibly assigned to gauges.
System bakeout program with control of temperature, time and over-pressure limit.
Integral K type thermocouple amplifier.
Automatic control of titanium sublimation pump with optional countdown / cancellation
of imminent firing.
RS-232C inteface for data logging and control.
Recorder output 1.0 V/decade.
1U high full width, steel cased instrument for easy rack mounting.
Operates from 110V to 240V, 50/60Hz supply

Specifications:
Controller
Pressure Display : Scientific notation or bar graph displays in mbar, Torr or Pascal.
Supply Voltage : 100V to 240V nominal at 48 to 65Hz, without adjustment.
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-AIG17G is recommended for optimum performance. Other Bayard-Alpert gauges are suitable without adjustment, other than sensitivity.
Range
From 1×10-3 to below 3×10-11mbar with a UHV gauge head with tungsten filaments. The low limit is dependant on gaugehead, cable construction and length and conditions of use. The upper limit is determined by the acceptable life of the filament and may 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 <1% within any decade from 0.1mA to 10pA, <5% to 1mA and <20% to 2pA at 25°C incoming air temperature. Slope temperature compensation <0.02% per degree Celsius. Differential linearity of the 12-bit A to D converter is less than 0.1 LSB. Emission current initial accuracy <2%, stability <1%.
Gauge Supplies
Grid: +200V in emission, +500V @ 60mA in degas. Filament: +50V bias, ≤12V @ ≤4.2A (tungsten), ≤2.6A (yttria) with filament power limited @ >30 Watts.
Pirani Gauge
Gauge Type
PM-PVU2 and PM-PVB2.
A constant voltage bridge circuit reduces contamination at high pressures.
Capacitance Manometer
Capacitance manometers of any manufacture having a +10 volt full-scale output at 1,10, 100 or 1000mbar or Torr and which are self powered are suitable.
