Introduction to General Performance Terms for Sensors

General Performance Terms for Sensors

A device which can feel the prescribed measurement and conver into a usable output signal according to a certain law is called a sensor.

It is usually composed of a sensitive element and a conversion element:

① Sensitive element refers to the sensor can directly sense (or response) the part to be measured. 

② Conversion element refers to the part of sensor which can convert sensitive elements sense (or response) of the measurement into an electrical signal suitable for transmission or measurement.

③ When the output is a prescribed standard signal, it is called a transmitter.

Specifications of sensor have a lot of professional terms, the data displayed by these terms, on behalf of the performance indicators of the sensors, is an important reference for us to understand whether the sensor to meet the needs of standard use.

Measuring range

The interval determined by the two values of the measurement within the permissible error limit.

Note: The high and low Z values of the measurement are referred to as the“upper limit”and“lower limit”of the measurement range respectively.

Measurement range

The algebraic difference between the upper and lower limits of the measurement range.
