Gauge pressure usually refers to the pressure difference between ambient, atmospheric pressure and the pressure in a vessel or line. A gauge pressure of zero would mean that the vessel or line was at atmospheric pressure. Normally the pressures of interest are ABOVE atmospheric so the gauge pressure is positive. Vacuum gauge pressure measures how far BELOW atmospheric pressure a vessel or line is. As such vacuum gauge pressure may be measured as a negative number - or for convenience it may be reported as a positive number with the caveat that it is "vacuum gauge pressure", meaning that the reported pressure is how far atmospheric pressure is above the pressure in the vessel or line.
A compound pressure gauge measures both positive and negative pressures relative to atmospheric pressure. It typically consists of two pressure sensors, one for measuring positive pressure (above atmospheric pressure) and one for measuring negative pressure (below atmospheric pressure). This type of gauge is commonly used in applications where both types of pressure need to be monitored, such as in HVAC systems or industrial processes.
Usually no difference at all. They can both move a pointer around a circular scale. The scale can be calibrated in both Inches of Mercury (InHg) or Millbars (Mb). An aneroid system can lend itself more easily to a digital display.

The pressure is balanced but not blank. There is still pressure on both side doing on to the wall.
A pressure gauge measures the pressure of a fluid or gas relative to atmospheric pressure, while a vacuum gauge measures pressures below atmospheric pressure. Pressure gauges typically have a positive scale, while vacuum gauges have a negative scale. Both gauges provide crucial information for monitoring and controlling pressure systems.
Both units are based on the imperial Pounds per Square Inch (PSI). The suffix A refers to Absolute pressure, while G refers to Gauge pressure. Gauge pressure is defined as the difference between the measured pressure and atmospheric pressure. Most pressure measuring devices (gauges) measure the gauge pressure, as one side of the gauge is exposed to atmospheric pressure.
A compound pressure gauge measures both positive and negative pressure in a system. Positive pressure is the pressure above atmospheric pressure, while negative pressure is the pressure below atmospheric pressure. This type of gauge is commonly used in applications where both types of pressure need to be monitored, such as in HVAC systems or industrial processes.

If it is vacuum a gauge oil filter. You have to buy a 3/8 pipe t fitting to fit the block and install both the sensor and the gauge tube on. Key on power wire to light it up.
A compound gauge is a pressure gauge that displays both negative and positive gauge pressure measurements. Gauge pressure is a measurement of pressure relative to ambient pressure. For example, if ambient pressure was 14.7 PSI and you were to measure absolute vaccum using a compound gauge, the gauge would indicate -14.7 PSI.
Pounds per square inch absolute (psia) is a unit of pressure that measures the pressure relative to a perfect vacuum. It takes into account the atmospheric pressure at sea level, which is approximately 14.7 psia. This means that a pressure measurement in psia includes both the pressure above atmospheric pressure (gauge pressure) and atmospheric pressure itself.
Transducer (i.e. a device for converting energy from one form to another) for both vacuum and positive pressure.
Transducer (i.e. a device for converting energy from one form to another) for both vacuum and positive pressure.
I'm Not exactly sure which one it is exactly but the best way to find out is to take a vacuum gauge and test both of them the one that is sucking in is the one you would use to recharge your ac system.
It should do just the opposite. I would check that gauge.
