MODEL 600 BAROCEL® CAPACITANCE MANOMETER 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 gettering material to ensure long-term In vacuum systems, the Model 600 is the ideal 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. • Wide range • High accuracy • High resolution - Repeats within 0.01% full scale after being • True total pressure - Reading independent of gas composition • High level output - 0-10 volts dc full scale, linear with pressure • Superior zero stability - Patented design eliminates errors due to temperature and overpressure effects • Stable zero reference Pirani Gauges • System versatility - Compatible with a variety of readouts and • Corrosion Resistant - Measuring cell constructed of Inconel/Monel for high corrosion resistance
