EPRB-2 Miniature Pressure Transducer

Brand: American Sensor Technologies Inc
Request Information Favorite
EPRB-2 is an ultra-miniature pressure transducer of 100% stainless steel welded construction. 

It is designed for severe environments where minimum size and light weight are required. Multiple interfaces such as pressure ports and electrical outputs, connection through cables or connectors have been designed to offer a wide range of adaptability to customer’s standards. 

EPRB-2 models have amplified output, either 5 Vdc ratiometric or 8-30 Vdc for use on vehicle, military, test equipment or on a test bench.
Features
  • Liquid and gas media compatible with Stainless Steel
  • Variety of available pressure ports
  • Variety of connector and cable outputs
  • IP66 rating for absolute pressure reference
