Wind Pressure Transmitter, Gas Micro Differential Pressure Negative Pressure Sensor

The differential pressure sensor is made of refined silicon piezoresistive differential pressure core, and the housing is made of aluminum alloy or stainless steel structure. The two pressure interfaces are M10 thread and plug structure, which can be directly installed on the measuring pipeline or connected through a pressure pipe. Widely used in the fields of dust removal equipment, boiler air supply, underground ventilation, power and coal industries, as well as in the process control of leakage pressure for beverage bottles and cans packaging materials such as paint and beverages.

The device deforms the sensor strain film by applying wind pressure, and outputs a 4-20mA or 0-10V standard signal after amplification processing. The range is ± 50Pa~100KPa, with a comprehensive accuracy of 0.5% FS~1.0% FS, a pressure resistance value of three times the range, and a mechanical interface standard of M10 × 1 thread. The shell is mostly made of aluminum alloy or stainless steel material, and some products have an IP65 protection level.

1.High precision and stability

By using imported pressure chips and diffusion silicon sensor technology, the pressure signal is linearized and output through a Wheatstone bridge. The long-term stability of the full zero position can reach 0.2 years;

2.Strong protection and reliability

Equipped with reverse protection and current limiting protection circuits, adopting a solid-state structure with no mechanical wear parts, suitable for harsh environments such as high temperature and humidity. Some products enhance their corrosion resistance through die-casting alloy aluminum shells and sealing processes;

3.Flexible installation and adaptability

Supports multiple interface forms and lead methods, with a sophisticated structure that is easy to integrate; Some models come with a digital display screen and button operation, supporting on-site parameter adjustment;
