Pressure Measurement Technology

High-speed Trains

High-speed trains operate in harsh environments (vibration and shock, dry and humid, extremely hot and severe cold, strong electromagnetic interference), and have strict requirements on the long-term stability and reliability of on-board equipment.

The pressure switch sensors we provide for high-speed trains featured with high electrostatic discharge, EFT (Electrical Fast Transient), surge (shock) immunity, high vibration resistance and shock resistance meet the service requirements of rail vehicles and thus win the recognition of customers.

Installation Occasion: pantograph system.      

Semiconductor Industry

Semiconductor production process requires high purity, high cleanliness, strong corrosion resistance, severe demands for leakage, high precision, explosion-proof and other operating conditions. Both pressure gauges and pressure sensors need the highest level of product.We have integrated special surface treatment technology, welding technology and super purification technology into special instruments for semiconductor industry, and we can provide customers with BA, GP, EP, UC products at all levels, according to the different stages of semiconductor production, as well as different process requirements.

Installation occasions: Gas transmission system, ultra-high purity water supply, liquid chemical raw material supply, liquefied gas and solvent measurement, etc.

Smart Cities

Internet of Things (IoT) technology promotes the construction of smart cities, and the role of perception layer (sensor) is of great importance. New fields put forward new requirements for sensors, i.e. long-term stability, resistance to environmental changes, high protection level, low power consumption, digital output, a variety of wireless communication modes and so on.

Our pressure sensors, throw-in type liquid level meters and other products are applied in Beijing Daxing International Airport, subways, Hangzhou Meeting Hall of G20 Summit, and received high praises from customers.

Installation occasions: Intelligent fire hydrant, building fire control, automatic fire extinguishing system, pipeline networks of water supply, agricultural irrigation, tunnel flood control, etc.

Hydrogen (New Energy)

We can supply 35MPa pressure gauges and pressure sensors (max. 70MPa) used for high-pressure hydrogen transmission equipment.

Safety is the first element of hydrogen products. Special structural design is adopted specifically for high-pressure hydrogen pressure gauges. Even if there are internal ruptures, no hydrogen leakage to the outside may happen. Pressure sensors have undergone ten-fold voltage withstand test and 10 million durability test. After special process treatment, hydrogen products can effectively prevent from hydrogen brittleness, thus ensuring high precision and durability.

Installation occasions: Hydrogen manufacturing plant, hydrogen transport vehicle, hydrogen storage tank, hydrogen vehicle hydrogen refueling station, domestic hydrogen fuel cell system, etc.

Power, Petrochemical and Other Process Control

The equipment of electric power and petrochemical industry requires high reliability (the equipment can’t be shut down, otherwise tremendous losses may be caused, so instruments for measuring fluid must have high reliability), and there are strict requirements for the accuracy, service life, long-term stability and reliability of pressure instruments.

We have cooperated extensively with five major power groups, PetroChina, Sinopec, and other major group companies, made joint efforts for the realization of safety, efficiency, energy conservation and environmental protection in products of customers, and won high recognition from customers.

Installation occasions: Thermal power plants, nuclear power plants, oil mining, chemical plants, etc.
