## Pressure Sensor Accuracy Formula

The following equation is used to calculate the Pressure Sensor Accuracy.

PSA = | MP-TP | / TP * 100

- Where PSA is the pressure sensor accuracy (%)
- MP is the measured pressure
- TP is the true pressure

## What is Pressure Sensor Accuracy ?

Definition:

Pressure sensory accuracy is a measure of the average variance a pressure sensor reads relative to the true pressure. This accuracy is often expressed as a percentage of the true pressure value.

## How to Calculate Pressure Sensor Accuracy?

Example Problem:

The following example outlines the steps and information needed to calculate Pressure Sensor Accuracy.

First, determine the measured pressure by the sensor. For this example, the measured pressure is found to be 50 pascals.

Next, determine the true pressure. The true pressure in this scenario is given is 52 pascals.

Finally, calculate the pressure sensor accuracy using the formula above:

PSA = | MP-TP | / TP * 100

PSA = |50-52 | / 52 * 100

PSA = 3.846%
