Edwards (formerly BOC Edwards) Vacuum Gauges and Vacuum Calibration

Model 600 Barocel ® Absolute Vacuum Pressure Transducer

The model 600 Barocel Transducer is an advanced design capacitance manometer which uses patented technology to improve zero stability after temperature excursions or pressure overloads. An integral vacuum reference of all-welded construction contains material to ensure long term stability.

In vacuum systems, the model 600 is the idea replacement for McLeod, Pirani, or thermocouple gauges. Since pressure is sensed by electrically measuring pressure induced displacement of a thin metal membrane, calibration accuracy is unaffected by the chemical composition of input media.

Model 600 Barocel ® Absolute Vacuum Pressure Transducer

Features and Benefits

Wide range
4 decades.
High accuracy – 0.15% of reading
High resolution – 0.01% full scale
Unaffected by overpressure – repeats within 0.01% full scale after being exposed to 2.4 bar (35 psia)
True total pressure – reading independent of gas composition
High level output – 0.10 volts d.c, full scale, linear with pressure
Superior zero stability – patented design eliminates errors due to temperature and overpressure effects
Stable zero reference
Alternative for McLeod, Thermocouple and Pirani gauges
System versatility – compatible with a variety of readouts and controllers
Corrosion resistant – measuring cell constructed of Inconel/Monel for high corrosion resistance
