INGCO S-GENS-OSE-CU, Big Gens Oil Sensor(S-GENS-OSE-CU)

product details:

In large generators, the engine oil pressure sensor plays a vital role in ensuring the smooth operation and longevity of the engine. Here’s a comprehensive description of its function, operation, types, and importance:

Function:

The engine oil pressure sensor continuously monitors the oil pressure within the lubrication system. This ensures that oil is circulating properly throughout the engine at sufficient pressure to effectively lubricate critical components like:

• Bearings
• Crankshaft
• Camshaft
• Pistons and connecting rods
• Valve train components

Without adequate oil pressure, friction between these components can increase significantly, leading to accelerated wear and tear, potential engine damage, and even catastrophic failures.

Operation:

The sensor typically consists of a metal housing containing a diaphragm or piston. This internal element responds to the variations in oil pressure. Here’s a breakdown of the operation:

1. Oil Pressure Changes: As the engine operates, the oil pump generates pressure that flows through the lubrication system.

2. Diaphragm/Piston Movement: The oil pressure pushes against the diaphragm or piston within the sensor.

3. Electrical Signal Conversion: The deflection of the diaphragm or piston is translated into an electrical signal proportional to the oil pressure. This conversion can be achieved through various methods depending on the sensor design:

   • Piezoelectric Effect: In some sensors, a piezoelectric crystal within the diaphragm generates a voltage proportional to the applied pressure.
   • Strain Gauge: The diaphragm’s deflection can cause a strain gauge to change resistance, influencing the electrical signal.
   • Differential Pressure Design: Some sensors might utilize a design with two chambers, one exposed to oil pressure and the other to a reference pressure. The pressure difference creates a deflection that’s converted into an electrical signal.

4. Signal Transmission: The generated electrical signal is sent to the Engine Control Unit (ECU) through wiring.
