Pfeiffer PCR 280 Compact Pirani Capacitance Combination Gauge Sensor KF16 NW16.
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.
They can be operated in connection with a Pfeiffer Vacuum controller for Compact Gauges or with another evaluation
unit. Compatible with TPG 261, TPG 262 & TPG 256A Pressure Display and Control Units. This is the PCR 280 Compact Pirani Capacitance Combination Gauge Sensor ONLY. Connection cable, control unit and hardware sold separately, see OPTIONAL ACCESSORIES below.
A complete specification brochure and operations manual is available, see AVAILABLE DOWNLOADS in PDF format below.
