Product Description

Model 433S Vacuum Transmitter is designed for applications of vacuum measuring or monitoring. Its measuring ranges are from 0~225torr through 0~525torr to ~750torr with the absolute pressure reference, or from -988~0 mbar through -700~0 mbar to -300~0 mbar with the gauge pressure reference.

In fact, the 433S Vacuum Transmitter is developed from 131S Pressure Transmitter, so it works on silicone piezoresistive technology.

In additional to G1/4” thread (male or female) as its standard process connection, an unique mechanical interface with 1/4″ VCR adaptor is specially developed for 433S transmitters to meet requirements for vacuum application. On request, BCM SENSOR can develop customized mechanical interface for this 433S Vacuum Transmitter.
