Pressure Sensor for Engineering Machinery

Rugged and Reliable Pressure Monitoring for Construction and Heavy Equipment

Engineering machinery operates under extreme conditions — high pressure, shock, vibration, dust, and temperature fluctuations. Our pressure sensors are specifically designed to provide accurate, stable, and long-lasting pressure measurement in hydraulic systems, braking systems, fuel lines, and cooling circuits of heavy-duty equipment.

Rugged and Shock-Resistant Design

✅ Vibration-resistant structure for mobile equipment
✅ Withstands strong mechanical shock and pressure spikes
✅ Compact body with IP67 or IP69K waterproof sealing

High Pressure and Overpressure Capability

✅ Pressure ranges up to 1000 bar
✅ Overpressure resistance up to 2× rated pressure, burst protection up to

Long Service Life and Zero Maintenance

✅ Over 10 million pressure cycles
✅ Sealed stainless steel diaphragm for oil, water, fuel, and hydraulic fluid compatibility
✅ Reverse polarity, surge, and EMI protection

Wide Operating Temperature Range

✅ Works in -40°C to +125°C, ideal for outdoor and engine compartments
✅ Temperature-compensated for stable output under variable conditions
