EPRB-2
Miniature Pressure Transducer
SPECIFICATIONS
Ranges from 0.6 to 700 bar (10 to 10,000 PSI)
Gage and absolute pressure references
Variety of pressure ports
Operating temperature up to 150 °C (300 °F)
0.5 to 4.5V or 4-20mA amplified output
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 thru cables or connectors have been
designed to offer a wide range of adaptability to customer’s
standards.
EPRB-2
models have amplified output, either 5V
DC
ratiometric or 8-30V
DC
for use on vehicle, military, test equipment
or on a test bench.
On request, Instruction documents can be provided to
ease the selection and use of our sensors and provide helpful
tips.
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
