Differential Pressure Transmitter Validyne
Model P55 Description
 The
Validyne Model P55 Miniature Differential Pressure Transmitter
is a compact Differential Pressure Transmitter designed for industrial
measurement applications. The variable reluctance sensing technology
allows the P55 to be used in a wide variety of low pressure measurements
where fast dynamic response, high resistance to vibration and
superior signal stability through ambient temperature change is
required. The Model P55 Miniature Differential Pressure Transmitter
will accept liquids and gases directly at the sensing diaphragm;
there are no internal fill fluids to slow the sensor response
or cause excessive temperature shift.
The Model P55 Miniature Differential
Pressure Transmitter is available in three output configurations:
4-20 mA current sink, +/-5 Vdc and isolated +/-5 Vdc outputs.
The 4-20 mA output is a true two-wire system and will operate
over any power supply from 9-55 Vdc.
The Model P55 Miniature Differential
Pressure Transmitter is also available in an absolute pressure
version with a welded variable reluctance sensor. Zero and span
controls are available for external adjustment, and the wiring
may be via connector or pigtail leads options. The P55 housing
is rated NEMA 4.
