Best Pressure Sensor Choices for Hydraulic Equipment

Industry Overview

Hydraulic systems work under high pressure, vibration, and frequent load changes. The pressure sensor must be stable, responsive, and built for tough environments so the equipment can stay protected and accurate under real operating conditions.

Common Pain Points

• High vibration near pumps and actuators
• Sudden pressure spikes during load changes
• Limited installation space on machine frames
• Need for reliable feedback to protect equipment

Typical Applications

• Hydraulic power units
• Presses and forming machines
• Cylinders and actuator feedback
• Test benches and machine control systems

Recommended Models

• DFP4800 Pressure Sensor
• DFP20 Miniature Pressure Transmitter
• DFP4200 Ultra-miniature Pressure Transmitter

Signal and Output Options

• 4-20mA
• Voltage output
• OEM custom signal options

Key Selection Points

• Select a sensor with enough pressure margin for peak hydraulic events
• Check response time and long-term stability for machine control
• Use the right diaphragm and seal material for hydraulic oil compatibility
• Choose compact dimensions when mounting space is limited
