Working principle

This series of sensors is based on different measurement principles to achieve precise perception and signal conversion of physical quantities. The core working mechanism is classified according to measurement types as follows:

4.1 Pressure Sensor (0399143)

Using the principle of diffusion silicon piezoresistive effect, when the measured pressure is applied to the isolation membrane of the sensitive element, the membrane undergoes slight deformation, causing the resistance of the diffusion silicon resistance bridge arm attached to its surface to change, thereby causing the bridge to output a voltage signal proportional to the pressure. The voltage signal is filtered and amplified by an internal signal conditioning circuit, converted into a digital signal by an A/D converter, and then output as a standard 4-20mA DC analog signal through a D/A converter. Intelligent sensors achieve the superposition and transmission of digital and analog signals through HART chips, supporting remote communication and parameter configuration.

4.2 Temperature Sensor (SY-0301060R)

According to the type, there are two principles: thermocouple type utilizes thermoelectric effect, and two different materials of metal conductors form a closed loop. When there is a temperature difference between the measuring end and the reference end, a thermoelectric potential is generated in the loop, and the magnitude of the thermoelectric potential is proportional to the temperature difference. After signal amplification, a standard signal is output; The thermal resistance type utilizes the positive temperature coefficient characteristic of metal resistors, and the resistance value of PT100 increases with temperature. The resistance change is measured by a constant current source circuit, converted into a voltage signal corresponding to temperature, and then regulated to output a standard signal.

4.3 Liquid level sensor (SY-1025115C)

Adopting the principle of ultrasonic/radar measurement: The ultrasonic type emits ultrasonic pulses to the liquid surface through a sensor probe, and the ultrasonic waves are reflected by the liquid surface and received by the probe. Based on the propagation time and speed of the ultrasonic waves, the distance between the probe and the liquid surface is calculated, and then converted into a liquid level height signal; The radar type emits high-frequency electromagnetic waves, utilizes the reflection characteristics of electromagnetic waves at different media interfaces, measures the round-trip time of electromagnetic waves, and calculates the liquid level based on the propagation speed. It is not affected by media temperature, pressure, or viscosity, and has higher measurement stability.

4.4 Multi parameter sensor (SY-1025120E)

Integrated pressure and temperature measurement unit, the pressure unit adopts the principle of diffused silicon, and the temperature unit adopts the principle of PT100 thermistor. The signals collected by the two sensitive components are processed by independent signal conditioning circuits, and then synchronously output through a data fusion chip. It can simultaneously output 4-20mA signals corresponding to pressure and temperature, or superimpose two digital signals on a single analog signal through the HART protocol to achieve efficient transmission of multiple parameters.
