• HVAC Systems: It can detect the temperature of the return air and supply air of the air - conditioning unit, and monitor the indoor and outdoor ambient temperature, providing data support for the accurate regulation of the temperature of the HVAC system .

Precautions for Use:

• When welding the lead wires, the soldering iron temperature should not be too high, and the soldering time should be strictly controlled to avoid damage to the internal structure of the sensor due to over - temperature.
• Keep a certain distance between the sensor and heat - generating components such as large - power resistors and power transistors to prevent local high - temperature interference from affecting the measurement accuracy.
• If the sensor is used in an environment with electromagnetic interference, it is necessary to shield the lead wires to prevent electromagnetic signals from coupling into the sensor's output signal and causing distortion.
