There are many technical parameters of temperature and humidity transmitters, and if users are not sure about these in the purchase process, it is very likely to buy the wrong one. We will analyze the measurement range, measurement accuracy, and output signal of the temperature and humidity transmitter. Measuring range of temperature and humidity transmitters: The temperature and humidity transmitter is the same as the measurement pressure and liquid level, and the range must be determined first. In general, the temperature range of the temperature and humidity transmitter is: -40°C~100°C, and the humidity range is: 0-100%RH. Accuracy class of temperature and humidity transmitters: Accuracy is an important indicator of temperature and humidity transmitters. In most cases, if precise temperature control is not available, or if the measured space is unsealed, a humidity and temperature transmitter with an accuracy of 5% RH ± is sufficient. For local spaces that require accurate control of constant temperature and humidity, or where it is necessary to track and record humidity changes at any time, a temperature and humidity transmitter with an accuracy of ± 3% RH or more is selected. The higher the accuracy of the temperature and humidity transmitter, the corresponding price will increase a lot. Output signal of temperature and humidity transmitter: The output signal of the temperature and humidity transmitter is in three forms, current type, voltage type and digital type. The current type of temperature and humidity transmitter is output signal of 4~20mA, and the output signal of temperature and humidity transmitter voltage type is 0-5VDC or 0-10VDC. The digital output signal of the temperature and humidity transmitter is RS485. Of course, when choosing the right temperature and humidity transmitter, I don’t know the selection of the above technical parameters, such as the protection level, power supply voltage, installation method of the temperature and humidity transmitter, etc., all need to be selected according to the specific site working conditions.
