The Simple Structure Directly Reflects The "Useful" Pressure Gauge Pressure Transmitter
Gauge pressure transmitter: The measurement reference point of a gauge pressure transmitter is "local atmospheric pressure". One side of its sensor diaphragm senses the process pressure, while the other side is directly exposed to the atmosphere. Therefore, its reading directly reflects the extent to which the process pressure is higher or lower than the atmospheric pressure.
Gauge pressure transmitters are used to measure pressure in non-hermetic systems or relative to atmospheric pressure.
| Characteristics | Relative Pressure Transmitter | Absolute Pressure Transmitter |
|---|---|---|
| Reference Pressure | Local atmospheric pressure (variable) | Absolute vacuum (fixed) |
| Zero Output | Outputs "0" (or 4mA) when exposed to atmosphere | Outputs "0" (or 4mA) at absolute vacuum |
| Measured Value | Pressure relative to atmospheric pressure | Pressure relative to vacuum |
| Affected by Weather/Altitude | Yes. Changes in atmospheric pressure can cause zero drift. | No. Its reference is a fixed vacuum. |
| Typical Applications | Pipeline pressure, tank pressure, pump pressure, and the vast majority of industrial processes | Vacuum systems, distillation towers, evaporators, meteorological research, and processes requiring absolute pressure for calculation (such as chemical reaction equilibrium) |
| Cost | Generally lower | Generally higher (due to the manufacturing of vacuum reference cavities) |
Gauge pressure transmitters are the "main force" and "default choice" in industrial pressure measurement. They are designed intuitively, in line with the common human understanding of pressure ("How many kilograms does the pressure gauge show?" refers to gauge pressure), and can meet the pressure measurement needs of over 80% of industrial sites.
