Flush type pressure sensor for food industry
2015-05-25

Hi sendo sensor, we need pressure sensors regularly, for food industry. The sensor must have a totally flush (flat) surface, I mean plain surface, without the ridge on the side, and the range we look for is near about 3 to 5 m water column. the sensor should have adjustment potentiometer for zero and span, many times at site this is needed and other companies also provide. The maximum temperature will be 85 deg C.



SS402 Series Flush Diaphragm Pressure Transmitter

***CE conformity
***Silicon oil filled
***Rugged Construction
***Output signals: 4 - 20 mA
***Measuring range: 0-0.3bar
***Field adjustable output range
***Stainless steel 316 diaphragm
***Typical G1/2” pressure connection
***Reverse polarity protection and current limit protection

Description
SS402 series flush pressure sensors utilize piezoresistive technology with a high performance silicon chip inside, the applied pressure acts on stainless steel 316L diaphragm, then pass to the silicon chip through silicon oil, available pressure ranges spanning from 5 psig up to 5800 psig. Typically applications: designed for use in food, process and industrial applications where the media is either viscous, or is otherwise liable to block the port of a conventional pressure transducer with a recessed diaphragm or pressure port.
