Capacitance Gauges CMR 375 (1 · 10-5 - 0.11 hPa), temperature controlled The capacitance diaphragm gauges CMR afford highly accurate vacuum measurements. The sensor is designed in ceramic technology, thus assuring only marginal zero drift and outstanding long-term and temperature stability. Measurement & Analysis / Measurement / ActiveLine CMR 375, 0.1 hPa F.S., pipe OD 1/2" Measurement range from 1 · 10-5 to 0.11 hPa Capacitive diaphragm gauge for ActiveLine Sensor in ceramic technology No memory effects Materials employed have identical temperature coefficients Excellent temperature compensation Resistant to corrosive gases Excellent zero stability Similar Image Additional protection against pollution by sensor shield Dimensions www.pfeiffer-vacuum.com Page 2 Measurement & Analysis / Measurement / ActiveLine Technical Data CMR 375, 0.1 hPa F.S., pipe OD 1/2" Accuracy: % of measurement Bakeout temperature max. at the flange Flange (in) Full scale Measurement range max.
