Applications of Pressure Sensors in Hydraulic and Pneumatic Systems

In hydraulic systems, pressure sensors play a critical role in ensuring the system operates within safe and optimal pressure ranges. They convert the pressure from hydraulic fluid into electrical signals that can be monitored to regulate pressures, prevent leaks, detect malfunctions, and optimize performance.

Typical applications include:

• Hydraulic Lifts and Cranes: Sensors monitor cylinder pressure to maintain safe lifting loads and prevent overloading.
• Heavy Equipment: Used in excavators, forklifts, and aerial platforms to manage high hydraulic pressures safely.
• Automotive Systems: Critical for regulating power steering and braking pressures.
• Industrial Manufacturing: Ensures stable pressure in hydraulic presses and injection molding machines.
• Load Monitoring: Pressure measurements help infer force being applied by hydraulic cylinders using the formula \(Force = Pressure \times Area\).

These sensors help avoid failures due to pressure spikes or drops, enhancing safety and reducing downtime.

Pressure sensors in pneumatic systems measure air or gas pressure to maintain effective operation of pneumatic components by providing real-time feedback for control systems.

Main applications:

• Air Brake Systems: Monitoring pressure ensures brakes on trucks, buses, and trains function correctly.
• Air Compressors & Vacuum Pumps: Sensors maintain consistent pressure levels to maximize efficiency.
• Pneumatic Actuators: Control pressure to regulate movement and force in automation and robotics.
• Compressed Air Engines: Monitor operational pressure for performance optimization.
• Air Filter Monitoring: Differential pressure sensors detect filter clogging by measuring pressure difference across filters, preventing system inefficiencies.

By integrating pressure sensors with regulators and valves, pneumatic systems sustain balanced airflow and prevent hazardous overpressure conditions.
