Differential pressure sensor characteristics

Micro differential pressure sensors are characterized by ultra-sensitive and stable offsets. The chip is based on thermal gas flow measurement and incorporates a microfluidic channel. This very narrow microfluidic pathway reduces the flow rate of gas into the gas. The extremely low gas flow rate ensures that the sensor does not have to be recalibrated after connecting the tubing and the filter.

The use of imported differential pressure integrated poor chip, the key components of the circuit part selected internationally renowned brand components, fully enclosed circuit, with moisture, anti-condensation, anti-leakage, lightning protection function. The shell is made of aluminum alloy or rusted steel. The two pressure ports are M10 threads or plugs. They can be mounted directly on the measuring pipe or connected through the pressure pipe. With characteristics of zero, full-scale, high precision, small temperature drift, strong anti-interference ability, stable and reliable, and low price, it has been widely used in various industries.

Widely used in boiler air supply, underground ventilation, central air conditioning, air duct wind, building automation and other power, coal industry pressure process, labor pressure requirements of the laboratory, fire engineering for indoor air pressure control areas. It is also called: differential pressure sensor, pressure difference sensor, duct pressure differential pressure sensor, indoor differential pressure sensor and so on.

The core component of the differential pressure sensor is a capacitive pressure sensor. A capacitor is formed by a stainless steel diaphragm and a fixed electrode, and its value changes with pressure.
