The 2450 Pressure Sensor has a one-piece injection molded PVDF body and ceramic diaphragm for superior compatibility in corrosive
liquids. These sensors are available with Digital (S
3
L) digital output or
fi
eld-scaleable 4 to 20 mA output. Select from three (3) pressure
ranges for optimal measurement resolution. Built-in temperature compensation provides outstanding accuracy over a wide operating
range. Versions with
1
/
2
in. union process connection are best suited for in-line installations.
Integral adapters (sold separately) may be used to create a compact assembly with
fi
eld mount versions of the 8250 Level Transmitter
and the 8450 Pressure Transmitter.
