Installation Guide
P528 OEM Refrigeration
Pressure Sensor
1. General Information:
A failure resulting in injury or damage may be caused by excessive overpressure, excessive vibration or
pressure pulsation, excessive instrument temperature, corrosion of the pressure containing parts, or other
misuse. Should you have any questions prior to installation, contact Kavlico.
2. Overpressure:
Caution – DO NOT exceed the pressure overload rating of the P528. Failure to comply may result in
irreversible electrical and/or mechanical failure to the pressure measuring and containing elements of the
P528.
Both static and dynamic overloads must be considered, especially if the P528 is going to be installed in a
hydraulic system application.
Hydraulic pressure fluctuations can result in very high and very fast peak pressures (i.e. water hammer
effect).
To avoid damaging liquid surges, fluid lines should remain full (if possible), pumps should be brought up to
power slowly, and valves should be opened slowly. To avoid damage from both fluid hammer and surges a
surge chamber should be installed.
If system pressure pulses are anticipated, select a P528 sensor with a pressure rating high enough to allow
continuous operation at the highest expected pressure spikes.
3. Freezing:
DO NOT allow freezing of process media in the pressure port of the P528. The P528 should be drained
(mount in a vertical position with electrical termination facing upward) to prevent possible overpressure
damage from frozen media.
4. Use in Life Support Devices:
The P528 is not recommended for use as a critical component in a life support device or system without the
express written approval of Kavlico.
WARNING
Read before installation of P528 Pressure Sensor
DO NOT use the P528 without reading the installation
guide in its entirety. Failure to do so may result in death or
serious injury.
