Refrigerant Pressure Sensor / Switch: Testing and Inspection

Inspection

1. Measure the pressure of high pressure line by voltage output between NO.1 and NO.2 terminals




2. Determine if the voltage is within spec.

Voltage =0.00878835 * Pressure + 0.37081095 [PSIA]


3. If the measured voltage value is not within specification, replace the A/C pressure transducer.
