Sensor's accuracy is impacted by operating temperature
Like any physical measurement system, pressure sensors are subject to errors caused by temperature variations, and these must be considered in sensor selection.
In applications with wide temperature variations such as down-hole drilling, automobile manifold pressure monitoring or autoclaves, the user must determine the maximum and minimum temperatures within which the sensor has to operate and find a unit that is compensated for these extremes.
If accuracy is an important parameter for the application, then temperature errors assume a larger importance, as accuracy will change significantly due to small changes in temperature.
The temperature range of a pressure sensor is normally specified in two ways: the operating temperature range and the compensated temperature range.
