The 971 UniMag transducer offers a measurement range from 1x10Torr to 5x10Torr 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.

The MKS The PDR900 power supply and readout unit is a stand alone, single channel controller for use with the Series 900 digital vacuum transducers. The instrument sets new standards for vacuum gauge controllers and can be used as a stand-alone power supply readout unit or as a tool for configuration, calibration and diagnostics of system integrated transducers in OEM applications. The PDR900 controller is the ideal solution for vacuum measurement, configuration of digital transducers and advanced system diagnostics. The controller features an easy to use menu-driven user interface, which guides the user through setup and configuration of remote transducer parameters. The readout unit communicates digitally with the transducer which eliminates analog measurement noise coupling via transducer cables. The unit automatically detects the 900 series transducer types, and can be used with both RS232 and RS485 transducers (Not compatible with 909/909A or 903 analog transducers).
