The Relevant Characteristics of NTC Sensor


The Relevant Characteristics of NTC Sensor

In the current temperature and humidity sensors in the industry, for temperature and humidity sensor is because of the different relevant characteristics of temperature and humidity sensor temperature and humidity sensor types are different, so the choice of temperature and humidity sensors, the need for comprehensive temperature-related characteristics of the humidity sensor, the sensor can be selected so that it fit our needs. Then the common sensor, the sensor which features, what does?

Characteristics of a sensor, static characteristics

Generally refers to static characteristics between the static input signal, the output of the sensor and the input of a certain relationship. Since this time, input and output and time are not related, so their relationship is a static characteristic of the sensor, he can use a free time variable algebraic equations or as abscissa with inputs, to correspond with him the output as ordinate and draw the characteristic curve to describe. Parameters indicating static characteristics of the sensor are: linearity, sensitivity, resolution and hysteresis and the like.

Two characteristics of the dynamic characteristics

It refers to the dynamic characteristics of the sensor input changes when its output characteristics. In practice, the dynamic characteristics of the sensor to respond to some common standard input signal to represent. Mainly because the sensor's response to the standard input signal more easily experimentally determined, but there is a certain relationship between its standard response to an input signal and a response to any input signal, the general case of the former can certainly know presumption of the latter. The most commonly used standard input signal and sine signal two kinds of step signal, so the dynamic characteristics of the sensor is also used step response and frequency response to be represented.

Three sensors features, hysteresis characteristics

Hysteresis characteristics generally means the sensor between the forward (input increases) and reverse (input decreases) trip to the input output characteristic curve is not the same degree, in general, with the greatest difference between the two curves △ MAX and full scale output F? S percentage representation. Hysteresis is generally present in the energy absorption caused by the internal components of the sensor.
