P528
Refrigeration Ceramic
Pressure Sensor
Typical Applications
High and Low Side Pressure Measurements
in Refrigeration Systems
Product Refrigeration
Refrigerant Recovery
Transport Refrigeration
Environmental Test Equipment
Description
The P528 incorporates Kavlico’s 4th
generation ceramic capacitive sense
element with the latest state-of-the-art ASIC.
Available with a brass or stainless steel
housing, the P528 has been specifically
designed for high volume OEM refrigeration
applications. It can endure the high vibration,
broad temperature ranges and humidity
conditions found in refrigeration systems
while withstanding high over-pressures and
pressure pulsations without damage or
degradation.
The P528 package has a built-in Metri-
Pack 150, electrical connector and supports
male and female pressure connections.
The P528 is offered with seal materials that
are suitable for many of the latest refrigerants
such as R134a, R22, R123, R12, R410A,
including many of the proprietary blends,
and associated lubricants.
