PULS Oil Level Sensor

Second Generation PULS (Packed Ultrasonic Level Sensor) Oil Level Sensor; Recording the liquid level (static and dynamic)

PULS Oil Level Sensor

 

  • Continuous measurement of the engine oil level in the static (engine stopped) and dynamic range (engine running)
  • Compact sensor architecture with a multi-chip module
  • Integrated temperature sensor
  • Immediate measurement after switch-on
  • Principally, also suitable for hydraulic and transmission oils

Customer Benefits

 
  • Continuous monitoring of the oil level, which prevents engine damage due to breaking the oil film
  • Highly resistant to impact and vibrations thanks to compact multi-chip module
