Why does my compressor have two gauges?
Industrial air compressors have two pressure gauges that indicate the PSI levels of the two key stages in the pressurization process. On the one hand, each gauge lets you know if the system is healthy. Moreover, each gauge helps you determine how energy gets generated inside the tank for use as air power.
What are the two gauges on the regulator used for?
Most regulators have two gauges. The high-pressure gauge shows the cylinder pressure. The low-pressure gauge shows the working pressure, or the pressure of the gas being delivered to the torch.
When to use high and low side A / C gauges?
It can be used for recharging refrigerant, or to diagnose an a/c system based on pressure readings from your gauges. In conjunction with a set of high and low side gauges, this temperature and pressure relationship charge can be used to diagnose an a/c compressor that is not working.
What should my AC pressure gauge reading be?
This is the second part of a series on AC pressure gauge readings. If you missed part I, start here. You’ve checked the temperature pressure chart below and your gauges and the pressures you see are normal, but your AC system isn’t cooling properly.
What does a low compressor pressure reading mean?
AC Compressor Pressure Readings & their Meaning Low Pressure Gauge High Pressure Gauge Inference/Action Required In range In range AC is working properly Low Low Add refrigerant Low High Need service, possibly blockage of the e High Low Need service, possibly faulty compressor
What does high pressure on AC compressor mean?
The compressor may be faulty. Higher Pressure on both the High and Low side may indicate an overcharge or lack of cooling at the Condenser. Higher than normal pressures on both high and low side with the correct amount of refrigerant, could mean a problem with air flow thru the condenser.
