Product Introduction

----------------------------------------------------------------------

Installed on a car gas tank or gas flow pipe for measuring gas pressure
Pressure range up to 1.5MPa, the output linear voltage signal
Special structural design, product IP67 protection class


What is the barometric pressure sensor:
The main sensor components of the barometric pressure sensor are: A pressure sensitive film within the pressure sensor, And a thimble open control, the circuit is connected to a flexible resistor. When the pressure of the measured gas decreases or rises, the deformation of the film leads to the thimble, and the resistance of the resistor will change. The resistance of the resistor changes. From the sensor components to obtain 0-5V signal voltage, after A / D conversion is accepted by the data collector, the data collector then passes the results to the computer in the appropriate form.
Pneumatic sensor characteristics

◆ standard thread pressure measurement method.

◆ All stainless steel construction, protection class IP68.
◆ measurement accuracy of up to 0.1 level.
◆ RS485, 4 ~ 20mA output optional.
◆ Polyurethane professional cable, high temperature, corrosion resistance.

Pressure sensor working principle

Some of the main sensing elements of the barometric pressure sensor are a pressure sensitive film, It connects a flexible resistor. When the measured gas pressure is reduced or increased, the film deformation, the resistance of the resistor will change. The resistance of the resistor changes. From the sensor components to obtain 0-5V signal voltage,
After A / D conversion is accepted by the data collector,The data collector then passes the results to the computer in the appropriate form.


The main components of some barometric sensors are varactor silicon boxes. when the outside atmospheric pressure of the variable silicon container is changed, monocrystalline silicon film box with the occurrence of elastic deformation, thereby causing a change in the capacitance of the silicon plate parallel plate capacitor.

Pneumatic sensors are made of isolated silicon piezoresistive pressure-sensitive components packaged in stainless steel shell made of. It can feel the liquid or gas pressure into a standard electrical signal external output, Air pressure sensor DATA-52 series is widely used in the supply / drainage, heat, petroleum, chemical, metallurgical and other industrial processes on-site measurement and control.
