2. Air particle detector temperature and humidity monitoring unit

The temperature and humidity monitoring unit is composed of two material conductors with different compositions to form a closed loop. When there is a temperature gradient at both ends, a current will pass through the loop. At this time, an electromotive force - thermal electromotive force - exists between the two ends. Two homogeneous conductors with different compositions are hot electrodes, the end with higher temperature is the working end, and the end with lower temperature is the free end. When the temperature of the measured medium at the working end changes, the thermoelectric potential changes accordingly. The thermoelectric potential is sent to the computer for processing, and the temperature value can be obtained. Humidity monitoring units are generally made of polymer film capacitors. When the ambient humidity changes, the dielectric constant of the humidity-sensitive capacitor changes, and its capacitance also changes, thus obtaining the humidity.

The product uses standard 35mm clamping rails, industrial-grade chips, and high-precision temperature and humidity probes to ensure the product's excellent reliability, high precision, and interchangeability. Using RS485 hardware interface (with lightning protection design), the protocol layer is compatible with the standard industrial Modbus-Rtu protocol. Compatible with various host platforms (PC software, touch screen, PLC, KingView).

3. Air particle detector wind speed and direction monitoring unit

The wind speed and direction sensor (transmitter) uses a high-precision magnetic sensor chip inside, and uses a low-inertia light metal wind vane to respond to the wind direction, with good dynamic characteristics. The meteorological wind speed sensor (transmitter) adopts the traditional three-point cup meteorological wind speed sensor structure. The wind cup is made of carbon fiber material, which has high strength and good start-up. The built-in signal processing unit of the cup can output the corresponding wind speed signal according to user needs, and can be widely used in meteorology. , ocean, environment, airports, ports, laboratories, industrial and agricultural transportation and other fields.

4. Air particle detector noise sensor

The noise sensor incorporates a sound-sensitive condenser electret microphone. Sound waves vibrate the electret film inside the microphone, causing changes in capacitance and producing a corresponding change in tiny voltage. This voltage is then converted into a voltage of 0-5V, which is accepted by the data collector through A/D conversion and transmitted to the monitoring chip.

The sensors used by our company use high-sensitivity pickups. The power supply, induction probe and signal output are completely isolated, the signal is stable and the accuracy is high. It has the characteristics of wide measuring range, good linearity, easy use, easy installation, and long transmission distance.
