PM241 Diffused silicon flat Film Pressure sensor

I. Food and Pharmaceutical Industry

1. Main application scenarios

CIP/SIP process monitoring: During the online cleaning and online sterilization processes, it is necessary to precisely monitor the pressure of the cleaning liquid and steam inside the pipelines and tanks to ensure the cleaning and sterilization effects. The sensor must be able to withstand high temperatures, high-pressure steam and corrosive cleaning agents.

Fermentation tanks and bioreactors: Monitor the tank pressure and liquid level during the fermentation process, and precisely control the aeration volume and metabolic process. The sensor is required to have high precision and excellent hygiene design.

Filling and packaging equipment: Control the air pressure or liquid pressure of the filling head to ensure the accuracy and stability of the filling volume.

Pipeline pressure and flow monitoring: Ensure smooth transportation of materials in the pipeline to prevent blockage or leakage caused by excessive pressure.

Ii. Hydraulic and Pneumatic Systems

1. Main application scenarios

Hydraulic system pressure monitoring

Pump outlet pressure: Monitor the working status of the main pump to prevent overload.

Pre-cylinder/post-cylinder pressure: Used to calculate output force and perform precise force control.

Valve block pressure feedback: As the feedback unit of the electro-hydraulic servo/proportional system, it realizes closed-loop control of pressure.

Pressure control of pneumatic system

Stable air source pressure: Ensure the stable operation of pneumatic tools and actuating elements.

Iii Pumps and Compressors

1. Main application scenarios

Application of pumps

Performance testing and monitoring: Measure the inlet pressure and outlet pressure of the pump, calculate key parameters such as head and efficiency.

Dry running protection: By monitoring the inlet pressure, it prevents the pump from running dry and burning out in a liquid-free state.

Closed-loop control and variable frequency drive: Based on the feedback of the outlet pressure, the pump's rotational speed is adjusted in real time to achieve constant pressure water supply/oil, thereby achieving energy-saving purposes.

Filter clogging monitoring: By measuring the pressure difference before and after the filter, determine whether the filter element needs to be replaced.

Applications of compressors

Monitoring of cylinder pressure and exhaust pressure at all levels: Optimize the operating efficiency of the compressor and prevent overpressure.

Air/gas flow calculation: Precise flow calculation based on temperature and pressure parameters.

Loading/unloading control: Automatically control the loading and unloading of the compressor based on the pressure of the pipeline network to save energy.

Iv. Mechanical Manufacturing and Factory Automation

1. Main application scenarios

Injection molding machines: Monitoring injection pressure, holding pressure, and mold clamping force are key parameters for ensuring product quality.

Machine tools: Used for pressure monitoring of hydraulic chucks, tool turrets and lubrication systems.

Press: It is used for precise pressure control of the press to achieve precise press-fitting.

Industrial robots: Pneumatic pressure control for robot grippers is used to achieve adjustable grasping force and prevent damage to precision workpieces.
