MKS HPS Series 979B Atmosphere to Vacuum MicroPirani, KF-16. MKS Part Number: 979B-31 The MKS HPS® Series 979B Atmosphere to Vacuum (ATV) transducer is a general purpose vacuum transducer that provides a wide measurement range, from 10-10 torr (UHV) to atmospheric pressure. The 979B combines both the MEMS-based MicroPirani™ and a miniaturized hot cathode sensor in a single housing for simplified gauge integration. The 979B can be operated via digital communication (RS232 or RS485) or as an autonomous analog unit. Degas and filament select can be controlled via digital communication, push button control from the top panel or analog connections. Customers requiring both a power supply and display can use the 979B with the PDR900 Series Controller PN P102879 sold on this website. For Complete Specifications and Operation Information See the DOWNLOADS section. Features & Benefits.Combined vacuum sensors and wide measurement range eliminates complex manifold, wiring and control requirements. MicroPirani™ is automatically zeroed during pump down cycle for improved accuracy. Patented degas function for ease of control and 3 user-configurable relays for process control.

MKS PDR900 Vacuum Gauge Controller for Series 900 Transducers 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).
