Kavlico product story

Jun 5, 2009
Kavlico has added the P528 OEM refrigeration pressure sensor with a 1/4 SAE female flare and Schrader deflator with 7/16-20 UNF internal threads to its P528 family of sensors.
This sensor, which incorporates Kavlico's fourth-generation ceramic capacitive sensing technology, has been engineered for high-volume original-equipment-manufacturer (OEM) refrigeration applications.
Packaged in a brass or plated steel housing, the sensor can endure the high vibration, broad temperature ranges and high-humidity conditions found in refrigeration systems while withstanding high overpressures and pressure pulsations without damage or degradation.
Pressure ranges are available from 0-100 through a 0-750 PSI absolute and sealed gauge.
Typical refrigeration applications include: high and low side pressure measurements in refrigeration systems; product refrigeration; transport refrigeration; refrigerant recovery; and environmental test equipment.
The P528 is offered with seal materials that are compatible with many of the latest refrigerants, such as R134a, R22, R123, R12 and R410A, as well as a host of the proprietary blends and associated lubricants.
The compact and lightweight sensor, which is less than 1.75in (4.45cm) long and weighs a maximum of 50g, features an external hex for quick and easy installation, according to the company.
It operates on 5VDC and provides a linear-amplified analogue output of 0.5VDC to 4.5VDC proportional to pressure.
The low-power-consumption device is said to have long-term stability and is temperature compensated over the entire operating range.
The operating temperature range is -30C to +135C.
The sensor is RoHS compliant and carries CE mark certification.
Kavlico is a business unit of Custom Sensors and Technologies (CST).
