Pfeiffer Part Number PTR26855 (Replaces The Discontinued PCR 260 PN PTR26850) The Compact Pirani Capacitance Combination Gauge PCR 280 has been designed for vacuum measurement of gases in the pressure range of 1000 to 10-4 Torr. The gauges must not be used for measuring flammable or combustible gases which react in air. The PCR gauge is a Combination Gauge consisting of a Pirani sensor and a Capacitive Diaphragm Sensor. Both sensors are constantly active. At low pressures, only the signal of the Pirani sensor is used for pressure measurement; at high pressures, only the signal of the capacitive diaphragm sensor is used. To determine the output signal in the intermediate range, both signals are used proportional to the pressure.
