HMP45D温湿度传感器的维护及校准

Maintenance and Calibration of HMP45D Temperature and Humidity Sensor

温湿传感器是用来同时测量空气温度和相对湿度的。由于传感器的测量部分经常与空气中的灰尘和化学物质接触,使传感器在某些环境下产生漂移。而仪器的电气参数会随时间的推移、温度变化以及机械冲击而产生变化,因此传感器需进行定期维护和校准。

The temperature and humidity sensor is used to measure the air temperature and the relative humidity in the same time .The some environment make the sensor produce shift by the sensor touch the air dust and chemistry, material .The electric parameter of the instrurnent also is change by time, temperature and machine shock, so the sensor needs maintain and calibrate regularly.
