The PMM-32-1 gauge transducer is a magnetic electric discharge sensor with a cold cathode of the inverse-magnetron type. Designed to convert a pressure signal into an electrical signal in the range from 1x10-7 to 1.3 Pa (from 7.5x10-10 to 1x10-2 mm Hg).
It is used as a sensor in vacuum gauges VMB-8, VMTsB-12 and VMB-14 in the power supply modes of these vacuum gauges.
