温湿度传感器的选型注意事项
第一注意选择温度区间、湿程需结合使用目的
First, pay attention to the choice of temperature range and wet range
由于专业的温湿度传感器的种类范围较多,其应用类型也千差万别,在选购该种仪器设备时要将它的温度区间以及湿度量程,与具体的使用目的和使用环境相结合,避免因选择量程过大或过小而影响探测的精度,降低性价比。
Because of the higher temperature and humidity sensor professional range, the application types vary widely, to its temperature range and the humidity range in the purchase of the equipment, combined with the specific purpose of use and the use of the environment, avoid the selection range is too large or too small and affect the accuracy of detection and reduce the cost.
第二注意常温中的探测精度勿过低
Second, pay attention to the detection accuracy at room temperature, not too low
一般来说在选购温湿度传感器时,需要以常温下的探测精度为准,特殊用途的设备可酌情购买。普通的温湿度探测器在超过40℃温度时,其探测精度有所下降,所以选购时也要注意二者的协调性。
Generally speaking, in the purchase of temperature and humidity sensors, the need to detect accuracy at room temperature shall prevail, special equipment can be purchased as appropriate. Ordinary temperature and humidity detectors at more than 40 degrees Celsius temperature, the detection accuracy has declined, so when we buy, we should also pay attention to the coordination of the two.
第三注意时漂和温漂不可过大
Third, pay attention to drift and temperature drift can not be too large
目前绝大多数行业领域使用的最好的温湿度探测器为电子式智能探测装置,该种电子智能装置的年时漂量较大,所以在选购时要注意其时漂和温漂参数,选购漂移量较小的产品,避免随着使用时间而降低探测精度。
At present, the vast majority of industries using the best temperature and humidity detector for intelligent electronic detection devices, the intelligent electronic device in a large amount of drift, so should pay attention to when choosing the time drift and temperature drift parameter drift, to buy smaller products, with the use of time to avoid and reduce the detection accuracy.
