Products > Pressure > Sensit Flush Diaphragm Transmitter
The M6420-92 is ideal for applications where the sensing element has to be in direct contact with the media. This enables measurement of media that contain particles or are liable to congeal. The M6420-92 pressure transmitter is based on a four active arm strain gauge bridge fused to a high purity ceramic diaphragm, offering high natural output coupled with superb chemical and corrosion resistance. It has a two wire, 4 - 20mA output proportional to pressure and is fully CE compliant. The sensing element and its associated electronics are housed in a rugged stainless steel case. It has a M24 x 2 threaded pressure fitting and a flush mounted sensor, sealed via an O-ring. |  |
