TPH3051DP/HP DIFFERENTIAL PRESSURE TRANSMITTER

The TPH3051DP/HP is a configurable industrial transmitter designed to measure the pressure difference between two process points.

Pressure applied to the transmitter’s isolation diaphragms produces a small movement in the metal capacitive sensing element. The internal measuring circuit converts this movement into a stable output signal, using linearization and temperature compensation to support consistent performance across changing process conditions.

Two configurations are available:

• TPH3051DP: Standard differential-pressure transmitter
• TPH3051HP: High-static differential-pressure transmitter

The transmitter can be configured with multiple measurement ranges, output signals, process connections, housing materials, and wetted-material combinations. Available communication options include standard 4–20 mA, HART, and RS485.
