The MKS HPS® Series 901P Plus Transducer has a combined sensor output that measures from 1x10 to 1,000 Torr for monitoring pump-down cycles. This unique patented transducer is designed specifically for the loadlock environment, the 901 Plus (901P) replaces up to three sensors in one compact package. The 901P provides both pressure measurement and atmospheric switching capabilities, by integrating the MicroPirani™ and piezo sensor technologies. The differential sensor ensures accurate atmospheric pressure sensing under varying barometric pressure conditions, for optimum loadlock performance. Customers requiring both a power supply and display can use the 901P 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).
