Humidity sensor is widely applied in many fields, particularly in the fields that record the temperature and humidity changes in real time. The temperature and humidity sensor can scientifically and effectively manage, analyze and summarize the recorded contents.
Application in the management of museum cultural relics and archives
It's another area for the application of temperature and humidity sensors. The archive papers can be kept for a longer time at a suitable temperature and humidity condition, once the temperature and humidity condition is changed, the paper will be crisp, important materials will also be lost. So it’s necessary to record the temperature and humidity of the archives, prevent the occurrence of malignant accidents. Application of temperature and humidity sensors simplifies the temperature and humidity record, saves the cost of cultural relics preservation and makes the work more scientific, prevents it from being disturbed by too much human factors.
When a new system is used for the first time or the meter, sensor is replaced, calibration must be made before use.
There are two kinds of calibration in general, one is the physical calibration (in this mode, two points needs to be calibrated, namely the zero position and the range), and another is the digital calibration.
Physical calibration is applicable for most weighing systems, and digital calibration is used in the fields when the physical demarcation can't be used. However, digital calibration can't eliminate the errors, its accuracy is related with the sensor’s sensitivity, range and wiring system (four-wire or six-wire), the division value or maximum range setting, as well as the signal loss on the junction box and cable.
The scale division and maximum range shall be set before calibration.
Before calibration, the instrument shall be powered on for at least 15 minutes until the sensors and meters reach the thermal equilibrium state.
