PSI-4/20 – Two-Wire Pressure Transmitter
Operational Description
Ideal Transmitter for Most
Fluid and Gas Measurement
PSI-4/20 offers infinite
resolution. Pressure ranges are
vacuum to 10,000 psi, gage or
absolute, high burst pressure is
10x full scale, and overall
accuracy is ±0.25% F.S.
(B.F.S.L.). An optional feature is
adjustment capability without
disassembly.
PSI-4/20 consists of
piezoresistive semiconductor
strain gages used in a full bridge
circuit. The output from the
bridge circuit is conditioned by
an integral electronics package
that generates a 4-20 mA two
wire output which is proportional
to input pressure.
Applications
Especially useful when there
are great distances between the
transmitter and the data
acquisition system, the PSI-4/20
offers a highly accurate
measurement with exceptional
durability and long life. Stainless
steel wetted surfaces make this
unit compatible with most fluids
and gases. The small size (3 oz.)
makes the PSI-4/20 ideal for use
where space is a concern without
sacrificing high accuracy.
