MKS 974B QuadMag Cold Cathode Transducer KF-40, 1 x 10-8 to 1500 Torr. PN: 974B-92020


MKS 974B QuadMag Cold Cathode Transducer KF-40, 1 x 10-8 to 1500 Torr.
MKS Part Number: 974B-92020


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 10-8 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 10-5 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 10-2 Torr. Unlike traditional Pirani gauges, the element in the MicroPirani™ is made of a one millimeter square silicon chip, allowing the measurements to be made in a very small volume. A traditional Pirani sensor has a measuring range from 10-3 to about 100 Torr, rapidly losing sensitivity above 10 Torr. Because the size of the sensing portion of the MicroPirani™ is so small, it has a range down to 10-5 Torr. The design minimizes the effects of convection, so operation is possible in any position without compromising accuracy, for simplified installation. The transducer includes a push button zero control than can be used when pressure is below 10-5 Torr.

The MKS 974B QuadMag Cold Cathode Transducer with digital communication allows for all adjustments and monitoring to be delivered real-time, via a host computer. The MKS 974B Transducer supports RS485 or RS232 communication as a standard feature. This 974B QuadMag Cold Cathode Transducer provides a 1 to 9 volt DC analog output signal at the male 15 pin high density D-sub connector. The transducer output is smoothed between the two sensors and reads from both sensors in the 5 to 15 Torr range.

For process control, the 974B has three independent relay setpoints. Features of the setpoints can be set, adjusted and monitored through the digital port. Like all thermal conductivity sensors, the MicroPiraniTM is gas-type sensitive. The Piezo measures independent of gas type. The 974B provides a digital leak detection output that measures differential reading between the Piezo and MicroPirani™. This makes it a simple solution for locating medium to fine leaks in vacuum systems. Customers requiring both a power supply and display can use the 974B DualTrans with the PDR900 Series Controller sold on this website.
