Product Applications
I. Application in Process Control
Application scenarios
Chemical and petrochemical processes: Pressure monitoring of reaction vessels, liquid level measurement of towers, and flow measurement of pipelines. The medium is often corrosive raw materials or intermediates.
Pharmaceuticals and biological fermentation: Pressure control of fermentation tanks to ensure a sterile environment. It is applicable due to its characteristics of no dead corners and high-temperature sterilization (CIP/SIP).
Food and beverages: Pressure measurement for viscous or granular materials such as syrups, concentrated fruit juices, and dairy products.
Water treatment and sewage treatment: Pressure monitoring of dosing systems, backwashing control of filtration systems, and pressure monitoring of sludge conveying pipelines.
Ii. Application in Environmental Control
Application scenarios
HVAC (Heating, Ventilation and Air Conditioning) system: Pressure monitoring of chilled water and cooling water pipelines; Boiler steam pressure control Static pressure measurement of VAV (Variable Air Volume System) ducts.
Compressed air system: Monitor the outlet pressure of the air compressor, the pressure of the air storage tank, and the pressure difference before and after the dryer, which is used for energy-saving control and equipment protection.
Energy management: Pressure and liquid level monitoring of ground source heat pumps and solar thermal utilization systems.
Iii. Applications in Water and Pneumatic Equipment
Application scenarios
Pumps and compressors: Inlet and outlet pressure monitoring, used for performance debugging, dry run protection and frequency conversion control. It is especially suitable for heavy-duty pumps such as mud pumps and slurry pumps.
Pneumatic tools and equipment: Provide stable air source pressure feedback to ensure consistent output force of the tools.
High-pressure cleaner: Directly monitor the high-pressure water pressure at the pump outlet and control the motor speed.
Hydraulic system: Although oil is the main fluid, ceramic sensors also perform well in water-based hydraulic oil or open systems that are prone to contamination.
Iv. Applications in Valves and Transmissions
Application scenarios
Intelligent pneumatic/hydraulic actuator: Integrated on the cylinder or hydraulic cylinder, it provides real-time feedback on the driving pressure and is used to achieve precise force control and position control.
Pressure regulating valve: As the "sense" of the valve, it provides signals before the valve, after the valve or pressure difference, achieving precise pressure closed-loop regulation.
Safety and braking system: In industrial brakes or safety clamping devices, monitor the clamping force to ensure safety.
V. Applications in Chemical Products and the Chemical Industry
Application scenarios
Storage, transportation and measurement of strong acids, strong alkalis and organic solvents: Pressure monitoring in all links from storage tanks to reactors.
The polymerization reaction process: Monitoring the pressure inside the high-pressure polymerization reactor is the key to controlling the reaction rate and product quality.
Chlor-alkali industry: Reliable measurement in highly corrosive medium environments such as chlorine gas and caustic soda.
Pesticide and dye production: Measuring the pressure of various intermediates and finished products.
