The 971B-91024 UniMag Cold Cathode Inverted Magnetron Vacuum Gauge offers a measurement range from 1x10-8 Torr to 5x10-3 Torr and features a size NW40 ISO-KF flange fitting. It has an RS232 digital communication interface for setup of transducer parameters and to provide real time pressure measurement. UniMag transducers are based on cold cathode inverted magnetron sensor technology. The 971B is a cost effective solution for base pressure measurement and control. All Series 970B transducers have an analog pressure output of 0.5VDC/decade that can be interfaced to external analog equipment for pressure readout or control. Other analog outputs and curves can be selected via the digital user interface. The Series 970B have standard 15 pin HD Sub-D connector. It can also emulate analog voltage outputs from a variety of other vacuum transducers. The emulation feature can be used to upgrade and replace other vendors’ gauges in OEM applications without changing system software. The integrated touch-screen display is user configurable; the user can change pressure units, orientation and has access to set point parameters as well as gas type. The display also indicates the status of the available set point relays. Displayed pressure reading from individual sensors or combined reading can be seen from >5 meters away on the high contrast display.
