The 974 QuadMag offers a measurement range from 1x10 to 1500 Torr and combines cold cathode inverted magnetron, MicroPirani™ and Piezo differential sensor technologies. The 974 has been specifically designed for pressure measurement within a vacuum loadlock. It has the capability to replace multiple pressure measurement devices on a loadlock with its absolute pressure measurement from atmosphere to 10Torr and atmospheric switching capabilities. Subsequently, OEM’s can reduce costs with a simplified loadlock design. The 974 can be used on loadlocks or any vacuum chamber requiring both absolute pressure measurement and atmospheric switching capabilities. The Series 974 QuadMag has RS232 or RS485 digital communication interface for setup of transducer parameters and to provide real time pressure measurement.

to 1500 Torr. RS232, Absolute Process Measurement. The MKS 974B QuadMag Cold Cathode Transducer belongs to the MKS 970 Series, a family of compact, low cost, general-purpose transducers that utilize from one to four sensors- cold cathode, MicroPirani™, and Piezo technologies. Combining these sensing technologies enables a wide measurement range from atmosphere to 10- Torr. In addition to its small size, broad range and lower cost, the 970 Series can be operated via digital communication or as an autonomous analog unit. The transducer measurement range is 10- to 1,500 Torr. The Piezo is a direct-reading absolute pressure sensor, allowing the measurement to be gas independent. The sensor includes a unique temperature compensation, allowing for high accuracy over a wide measurement range. The Piezo will measure from 10-1 to 1,500 Torr.The MicroPirani performs an autozero function to the Piezo when pressure is below 10-

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).
