PrintP158 Refrigeration Pressure Sensors
The P158 refrigerant pressure sensor is compatible with all fluorocarbon refrigerants and refrigerant oils now in use and in development for refrigeration and HVAC/R applications. Kavlico utilizes our field-proven ceramic capacitive sensing technology designed for automotive and other industrial application in the design of the P158.
The P158’s package design can endure high vibration and broad temperature range conditions found in refrigeration systems. The sensors can withstand high overpressures and pressure pulsations without damage or degradation in performance.
Operating on 5 Vdc, the P158 has an amplified, high-level linear output and is temperature compensated over a range of -34°C to +120°C.
Available in absolute, sealed gage and gage pressure versions, the P158 can be supplied in ranges from 0 – 100 to 0 – 750 PSI. The sensor has a machined brass housing and can be configured with a 1/4" Male Pipe Thread or 1/4" SAE Female Thread with Schrader Deflator process connection.
Specifically intended for high volume, OEM applications, the P158 delivers a cost-effective solution without compromising on performance or reliability. Kavlico offers the P158 in specific OEM pressure ranges in addition to the standard pressure configurations noted on the Data Sheet.
In addition to the P158 Refrigeration pressure Sensor, Kavlico designs and manufactures custom sensors for a wide variety of OEM, application specific requirements utilizing our ceramic capacitive, silicon micro-machined integrated capacitance and piezoresistive technologies.
