If you’re wondering about the accuracy of the [TE](https://www.digikey.com/en/supplier-centers/te-connectivity-measurement-specialties) pressure sensor [M5231-000005-300PG](https://www.digikey.com/en/products/detail/te-connectivity-measurement-specialties/M5231-000005-300PG/6004238?s=N4IgTCBcDaILIFYwGYCMBaADN7D3OwAUBxEAXQF8g), we have some clarity to offer you.

> The TE Connectivity sensor **M5231-000005-300PG** has an accuracy of ±0.25% full scale.  
> TE has confirmed that this accuracy applies to the **pressure range of 0 to 300 psi** , not the output voltage range of 0.5 to 4.5 V.

Sensors often create confusion when it comes to understanding accuracy and resolution, as these terms are sometimes used interchangeably.

For a clearer understanding of sensor accuracy:

- **Accuracy** is the sensor’s or instrument’s degree of veracity – **how close a measurement gets to the actual or known value.** To check the accuracy means to check how close a reported measurement is to the actual value.  
Accuracy is essential in safety-critical applications like medical equipment, automotive systems, and industrial processes. For example, a sensor with ±2% accuracy on a 100 V reading could range from 98 V to 102 V, impacting precision-critical environments.

- **Sensor Resolution meaning** on the other hand is **the smallest distinguishable change the sensor can detect and display.** The higher the resolution (thus, the smaller the distinguishable and displayable change) – the more **specific** are the values.  
For instance, a digital multimeter with 1 mV resolution on a 3 V range can show changes as small as 0.001 V.

In conclusion, while accuracy and resolution are closely related, they represent different aspects of a sensor’s performance. Accuracy measures closeness to the true value, and resolution determines the smallest detectable change. Understanding both is vital for selecting the right sensor for specific applications.
