Similar to a gauge pressure transmitter, but its reference pressure is a fixed, sealed atmospheric pressure (usually at sea level). It is useful in environments where atmospheric pressure changes significantly, such as high altitudes or deep-sea applications.
✅ Example: In mountainous regions (where atmospheric pressure is lower than 1 bar), a standard gauge pressure transmitter may show incorrect readings, while a sealed gauge transmitter provides more accurate measurements.
