P250/P251
Description
Technical Specifications
The P250/P251sealed industrial pressure
sensors are based upon Kavlico’s oil-filled
piezo-resistive (PRT) sensing technology
with the latest state-of-the-art ASIC.
Rugged by design, these highly reliable
sensors have a 304L welded stainless steel
housing and isolation diaphragm and are
well suited for a broad range of media
including air, fluids, and gases that are
stainless steel compatible. The sensors
provide a linear amplified output
proportional to pressure of 0.5 to 4.5 Vdc.
The P250/P251 package design has a wide
variety of both electrical and process
connector options to suit application-specific
requirements. The sensors have an
extremely high overpressure capability.
The P250/P251 sensors deliver a cost-
effective solution without compromising on
performance or reliability.
