For specific applications in different fields, when selecting the temperature sensor, we need to consider different factors, such as the environment used, what effects we need to achieve, we can also choose the brand according to the characteristics of different brands. Sensor used.
 

First of all, the temperature sensor must choose the sensor structure so that the sensitive element stipulates that the measured fluid or the surface temperature is measured within the measurement time. The temperature sensor output is only the temperature of the sensitive component. In fact, it is often difficult to ensure that the sensor indicates the temperature of the object.

1. Select the measurement range

 

Like the measurement weight and temperature, the measurement range must be determined first. Except for meteorological and scientific research departments, general wet (0-100%RH) measurement is generally required for temperature, humidity measurement.

 

2. Select measurement accuracy

 

Measurement accuracy is the most important indicator of humidity sensors. For each increase -percentage point, for the humidity sensor is the previous step, or even the previous grade.

 

3. Consider drift and warm drift

 

In actual use, due to the effects of dust, oil pollution, and harmful gases, the use time is long, and the electronic humidity transmission will produce aging, the accuracy decreases, and the annual drifting volume of electronic humidity transmission is generally about ± 2%, or even more. high. Under normal circumstances, the manufacturer will indicate that the valid use time of 1 calibration is 1 year or 2 years, and the expiration needs to be re -calibrated.
