Hella Oil Sensors Monitor Oil Level, Quality

PLYMOUTH, Mich. – Hella has launched the second generation of its ultrasonic oil sensors, which the company claims will help manufacturers achieve new emissions standards while making it easier for vehicle owners to monitor oil levels.


With Hella’s oil sensor, drivers will no longer have to guess when their oil needs to be changed, or rely on the old adage of changing motor oil every 3,000-5,000 miles, according to the company. Extending the life of a full charge of engine oil can potentially reduce carbon dioxide (CO(2)) by more than six grams per mile.


"We developed a robust, ultrasonic sensor that can operate in the harsh conditions of an internal combustion engine, while monitoring overall oil levels," said Dr. Martin Fischer, president of Hella’s U.S. Corporate Center with responsibility for the automotive supplier’s lighting, electronics and aftermarket business units in the United States. "We also have a premium version of the sensor that checks viscosity. This novel oil-quality sensor will determine when the oil has degraded or become contaminated by soot, fuel, water or coolant leaks."


Called the PULS (packaged ultrasonic level sensor), Hella’s second generation oil-level sensor has been standard equipment on a number of European vehicles since 2006. The first generation of oil level sensors was introduced in 1994 and since captured a 60 percent market share in Europe. Hella’s premium version of the oil sensor, called PULS+C (packaged ultrasonic level sensor + condition), also monitors oil quality.


The PULS and PULS+C sensors use multi-chip module technology that has nearly halved the number of parts per sensor when compared to Hella’s previous version. The sensor has a dampening cup that reduces the currents, turbulence and surface movements in the oil pan that are caused by engine operation and vehicle movement. If the oil level is too low, the sensor will notify the driver of the exact filling requirement.


The PULS+C continuously monitors key oil properties including viscosity, density and permittivity (dielectric conductivity). It can match oil-change intervals to the respective engine and consumers’ driving styles.


"Our PULS+C offers several distinctive advantages," Fischer added. "By detecting extreme oil conditions or foreign substances, Hella’s oil-quality sensor provides an early warning to drivers and can help prevent excessive engine wear and damage."


Additionally, Hella is developing a dynamic oil-pressure sensor for 2010. This will allow the electric oil pump to be intelligently controlled so that it will provide the optimum oil film for different engine operating states. This will trim the oil pump’s energy consumption, contributing to better fuel economy.


"Our PULS sensors are compact, reliable and cost-effective, but there’s one other advantage – automakers can eliminate the oil dipstick," Fischer said. "In the old days of the auto industry, motorists measured the amount of gasoline in their tanks using a measuring stick. We don’t do that anymore.


"Hopefully, future motorists will no longer have to contend with going into the engine compartment and hunting for the oil dipstick with a rag in hand. That’s a job where you don’t want to be wearing a nice outfit."
