PM220 pressure transmitter
Product Application
Applications in mechanical equipment
Pressure monitoring of industrial machinery
Hydraulic or pneumatic systems for injection molding machines, compressors, CNC machine tools and other equipment, which monitor oil pressure/air pressure in real time to ensure the normal operation of the equipment.
Lubrication system monitoring
Monitor the lubricating oil pressure in parts such as gearboxes and bearings to prevent mechanical wear caused by insufficient oil pressure.
Technical advantage
High sensitivity: The diffusion silicon chip responds rapidly to minute pressure changes (in milliseconds), making it suitable for dynamic pressure monitoring.
Overload resistance: Some models can withstand overvoltage of over 200%, making them suitable for mechanical shock environments.
Applications in hydraulic and pneumatic devices
Hydraulic system
Pressure monitoring of hydraulic cylinders in construction machinery (excavators, cranes) to achieve load-sensitive control.
Pressure protection for the hydraulic pump station to prevent overpressure from damaging the pipelines.
Pneumatic system
Pressure regulation of factory pneumatic circuits (such as cylinders and valves) to ensure consistent operation.
For example: Insufficient air pressure alarm in an automated production line.
Applications in locomotives (rail transit and automobiles)
Fuel/lubricating oil pressure monitoring
Real-time monitoring of engine fuel injection pressure and oil pressure ensures the safety of the power system.
Braking system
Pressure detection of brake air lines for high-speed railways/subways to ensure the speed and reliability of braking response.
Cooling system for new energy vehicle battery packs
Monitor the coolant pressure to prevent the battery from overheating.
