Since temperature affects the measuring accuracy of a pressure sensor, there always remains a small temperature error in the rated temperature range despite a wide range of compensation measures. Clueless is often expressed in the info sheets of manufacturers of pressure sensors as temperature coefficient (abbr. TC). This coefficient describes a (linear) error, beginning with a reference point, which generally is room temperature.
Accordingly, the temperature error at room temperature is zero and increases with increasing difference of the temperature from room temperature with the specified coefficient in linear fashion (see figure). Basically, not only the zero-point temperature coefficient (abbr. TC0), but also that of the span (TCC) should be taken into account individually. The zero-point error describes the result of temperature on the zero signal. Faux of the span specifies the result of temperature on the entire scale value. The average person temperature coefficients of zero point and of span are often specified as magnitudes, and therefore they could be either positive or negative.
If within an individual instrument the zero-point error has the same sign because the error of the span, these two temperature errors may add up in worst case. A typical value for the average zero-point temperature coefficient of a pressure sensor is: 0.2 % / 10 K. Link to WIKA pressure sensors.
