A pressure interface converts the selected pressure sensor's response into usable measurement information.

## In plain English

### What does Pressure measurement interface mean?

A pressure interface converts the selected pressure sensor's response into usable measurement information.

### A simple example

A control system can read a pressure transducer through its matching measurement electronics.

### What the drawings help you do

Identify the pressure sensor and its reference convention, such as gauge, absolute or differential pressure where applicable. Then show the conditioning and output interface. A voltage or current signal only represents pressure after the selected range and scaling are known.

### Before using this reference

- Identify the pressure reference and measurement range.
- Show the sensor and conditioning/interface boundaries.
- Reference output scaling, supply and connection requirements.

### Can the electrical output alone tell me the pressure?

Only when its relationship to pressure is known. The selected sensor’s range, reference and scaling determine how a received electrical value should be interpreted.

### Terms

- Gauge pressure: Pressure expressed relative to the selected atmospheric reference.
- Scaling: The defined mapping from sensor output to reported pressure.

## What it represents

A pressure interface converts the selected pressure sensor's response into usable measurement information.
A control system can read a pressure transducer through its matching measurement electronics.
Identify the pressure sensor and its reference convention, such as gauge, absolute or differential pressure where applicable. Then show the conditioning and output interface. A voltage or current signal only represents pressure after the selected range and scaling are known. This is original functional artwork, not a certified standard graphic or device pinout.

## How to read it

- Identify the pressure reference and measurement range.
- Show the sensor and conditioning/interface boundaries.
- Reference output scaling, supply and connection requirements.
- The sensor's pressure reference and range must be known; an electrical signal alone does not define them.

## Information to show or reference

- Identify the pressure reference and measurement range.
- Show the sensor and conditioning/interface boundaries.
- Reference output scaling, supply and connection requirements.

## Important distinction

The sensor's pressure reference and range must be known; an electrical signal alone does not define them.

## Facts
