Edwards (formerly BOC Edwards) Vacuum Gauges and Vacuum Calibration

Vacuum Measurement and control systems - Edwards (formely known as BOC Edwards) vacuum guages

Edwards (formerly BOC Edwards) ASG Active Strain Gauge

2000 to 1 mbar ASG Active Strain Gauge

note: ASG adapter cables supplied separately. This cable must be used with TIC, ADC & ADD.

The Edwards (formerly known as BOC Edwards) Active Strain gauge is a rugged, corrosion resistant diaphragm gauge which provides accurate, gas independent measurement from 2000 mbar to 1 mbar. It can be used as a stand alone transducer allowing OEMs and system builders to develop low cost, flexible solutions to their vacuum instrumentation needs. Alternatively, it can be connected to the Active Gauge Controller where it can be combined with many other sensor types to provide a complete vacuum instrument solution.

ASG Active Strain Gauge

Features and Benefits

Drive electronics combined in the gauge head
Simplifies system design
Saves valuable rack space
Wide range, regulated, internal power supply
Runs from standard d.c power supplies
+13.5 to +36 V
Tolerant to voltage fluctuations
Standard analogue output 0 to +10 v d.c.
Easy to interface with a computer or PLC
High accuracy and stability
Accuracy ±0.2% full scale
Stability ±0.2% full scale
Corrosion resistant, rugged design
Only material exposed to vacuum is stainless steel 316
Enclosure rating IP65
Gas independent measurement
Pressure measurement is completely independent of gas type making this gauge ideal for applications where gases other than nitrogen are used
Excellent high pressure resolution
Ability to resolve 1 mbar changes in system pressure even at pressures near atmospheric makes the gauge ideal for monitoring large, slow pumping systems
Part of the Active Gauge Range
Standard supply requirements and output voltage allow simple integration into systems using Pirani, thermocouple, inverted magnetron, strain, wide range and ionisation gauges. All of these are compatible with the Active Gauge Controller, a multi channel digital display and controller
