TPH3051GP/GA GAUGE/ABSOLUTE PRESSURE TRANSMITTER

The TPH3051GP/GA Gauge & Absolute Pressure Transmitter is designed for accurate pressure monitoring in demanding industrial systems.

The GP configuration measures gauge pressure relative to atmospheric pressure, while the GA configuration measures absolute pressure relative to a sealed vacuum reference. This allows the same transmitter family to support applications ranging from routine pipeline monitoring to processes requiring a true absolute-pressure reading.

A metal capacitive sensing element detects small changes in the isolation diaphragm and converts them into a stable electrical signal. Integrated linearization and temperature compensation help maintain dependable performance as operating conditions change.

The transmitter supports standard industrial outputs, including 4–20 mA, HART, and RS485. Pressure range, process materials, housing, thread connection, and optional accessories can be selected for the application.
