Hella 013680161 Packaged Ultrasonic Oil Level Sensor

The Hella 013680161 is a Packaged Ultrasonic Level Sensor (PULS) designed for continuous monitoring of engine oil levels in both static and dynamic conditions. This advanced sensor uses ultrasonic technology to accurately measure oil levels while simultaneously monitoring oil temperature, providing critical engine management data to your vehicle's ECU.

Key Features:

• Multi-chip module architecture integrating ultrasonic sensor, temperature sensor, and ASIC for enhanced shock and vibration resistance
• Damping cup design reduces turbulence and surface movement in the oil pan for accurate dynamic measurements
• Vertical flush-mount installation from below into the oil pan bottom
• Continuous oil level and temperature monitoring with real-time data transmission
• PWM output signal encoding both oil level and temperature information
• Compatible with OEM part number LR012640 for Land Rover applications

The sensor operates by emitting an ultrasonic signal that reflects off the oil-to-air boundary surface, measuring the transit time to calculate the precise oil level. If oil levels become too low, the sensor notifies the driver of the exact filling requirement through the vehicle's warning system. The compact multi-chip design offers superior durability compared to traditional sensors with multiple electronic components, making it ideal for the harsh operating conditions inside an engine oil pan.
