## Description

The Hydraulic Pressure Sensor block represents an ideal hydraulic pressure sensor, that is, a device that converts hydraulic pressure differential measured between two points into a control signal proportional to this pressure. The sensor is ideal because it does not account for inertia, friction, delays, pressure loss, and so on.

Connections A and B are conserving hydraulic ports connecting the sensor to the hydraulic line. Connection P is a physical signal port that outputs the pressure value. The sensor positive direction is from A to B. This means that the pressure differential is determined as $p={p}_{A}-{p}_{B}$.

## Ports

The block has the following ports:

`A`

Hydraulic conserving port associated with the sensor positive probe.

`B`

Hydraulic conserving port associated with the sensor negative (reference) probe.

`P`

Physical signal port that outputs the pressure value.
