MKS HPS 971 UniMag Transducer NW25 RS232, KF 25, 10-3 to 10-8 Torr
MKS HPS 971 UniMag Transducer NW25, RS232, KF 25, 10-3 to 10-8 Torr SubD male no relay, PN 971B-21030

The 971 UniMag transducer offers a measurement range from 1x10-8Torr to 5x10-3Torr and is based on cold cathode inverted magnetron sensor technology. The 971 is a cost effective solution for base pressure measurement and control. The Series 971 UniMag has RS232 or RS485 digital communication interface for setup of transducer parameters and to provide real time pressure measurement. The 971 UniMag transducers also has 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 971 UniMag has up to three mechanical relays which can be used for process control, examples are interlocking valves or pumps. The 971 UniMag Transducer has a user changeable cold cathode anode module that offers easy serviceability without disassembling of transducer electronics. Customers requiring both a power supply and display can use the 971 UniMag with the PDR900 Series Controller sold on this website.
