The oil level sensor is located in the vehicle's oil pan and is mainly responsible for measuring the oil level and sending that information to the vehicle's main control unit. The E90 oil level sensor keeps the motor oils at the desired level for better functioning.
There are two main types of this oil sensor, which include:
Resistive Sensors
A resistive oil sensor uses resistance to measure the oil level in the tank. The tank has two plates where one plate is submerged in oil and the other one is not. When the oil level rises, it means that temp and resistance decrease and this leads to the generation of an electrical current between the two plates. This current generates voltage proportional to the oil level in the tank. When the oil level decreases, voltage increase and this rise changes the resistance in the tank.
Capacitive Sensors
The capacitive oil sensors work based on capacitance measurement to indicate the level of oil in the tank. These sensors have two conductive plates that form a capacitor. When oil is present in the tank, it acts as an insulator and reduces the capacitor. When the oil level increases, one plate of the capacitor is submerged in oil and the other one is above the floor where it billows, causing the capacitance to increase. Decrease in oil level causes decrease of capacitance that results in change of the oil level.
The E90 320i partsare designed with superior quality materials and constructions to provide enhanced durability. Here are some of them:
Internal Monitors
Oil sensors are important in monitoring the health of the internal vehicle. This means they play a role in preventi,e damage by notifying the driver when oil is below or at dangerous levels. It also helps in knowing the possible leaks that can be encountered and where to do maintenance work.
Stainless Steel Housing
The housing of the E90 oil sensor is made from stainless steel materials. Stainless steel is a weather-resistant material that is not easily corroded by moisture, chemicals, or extreme temperatures, therefore assuring the long-lasting performance of the sensor. Other than that, stainless steel also provides rigidity required to protect even the most delicate internal components from external mechanical damage.
High-strength Plastic
The E90 oil sensor also comes with high-strength plastic material that provides better durability and is lightweight at the same time. Plastic can resist impact, therefore making the sensor more durable in extreme weather or environmental conditions. The plastic insulation surrounding the E90 oil sensor keeps the internal components protected from electrical interference that can potentially affect the sensor's performance.
Sensors
The E90 oil sensor is designed with the capacitive sensor technology that enables it to measure the variation in capacitance due to oil level changes. The sensor uses dielectric constant that pertains to oil substance. Capacitive sensors are contactless, making them ideal for automotive applications since they measure levels without coming into contact with possibly hazardous materials.
Resistance Temperature Detectors (RTD)
The E90 oil level sensor also comes with resistance temperature detectors, which are temperature sensors used to measure accuracy. It works by measuring oil temperature difference as a function of resistance, which leads to very accurate measurement results. RTDs are durable and provide excellent performance in numerous temperature levels.
Oil Level Measurement
The E90 oil sensor comes with precise oil level measurement. The sensor helps in monitoring current oil levels in various automotive applications such as vehicles with internal combustion engines, electric cars, heavy-duty trucks, and buses. Therefore, just like in other vehicles, the E90 oil sensor measures the oil level in BMW 3 seriesso that the driver does not encounter dry sumping or overfill.
Engine Protection
This is the most important aspect of any fluid monitoring system. The oil level sensors sense the amount of floating substance in the oil. If it goes lower than allowed, it can cause the engine to work harder in order to get the oil. This might lead to overheating and even serious internal damages. The E90 oil sensor is important in helping people avoid this situation by sending alerts whenever the oil dips below the ideal level.
Cost-Effective
The E90 oil sensor makes it easy for the car owner to do oil maintenance by providing accurate readings. This saves costs since it helps avoid extra expenses with repairs from engine wear and tear, which happens when the oil level runs low.
Having the right sensory oil level is important for a range of applications. Here are some factors one needs to consider when purchasing this product online:
Compatibility
The E90 oil sensor should be able to fit the existing model of the oil pan and the vehicle's internal control system. Various brands and models might have distinctive oil level sensors, so ensure you get one that is compatible with your equipment. You can do this by looking up the brand on various online platforms or contacting the manufacturer directly.
Technical specifications
The E90 oil sensor uses a capacitive or resistive method to determine the oil level. Each of these techniques has its own advantages. For instance, capacitive sensors are high-accuracy sensors, while resistive sensors are more cost-effective. Find more about it and get the one that meets your needs.
OEM vs Aftermarket
OEM sensors are manufactured by the manufacturer of the vehicle, and these provide the best performance since they are designed for a specific vehicle. Aftermarket oil sensors are manufactured by third parties and they might provide a more affordable solution. While they might not provide the same quality as OEM, some high-quality aftermarket oil sensors can work just as fine. weigh cost against quality and decide.
Reviews and Recommendations
Before spending any amount, refer to customer reviews and expert opinions on different brands and models to gather information about their performance and reliability. Generally, there are forums where oil sensors owners discuss their experiences with the products. This provides detailed insight that can help make the final decision.
Budget
There are many kinds of E90 oil sensors, and each is priced differently. Having a budget will help you look for a decent oil sensor that will work for you. Make sure to get the actual cost of maintenance and installation along with the purchase price.
The replacement rate of the oil sensor depends on factors such as the kind of oil used, the amount of driving done, and the environmental conditions. Generally, the oil sensor should be replaced after every routine maintenance check or after change in vehicle performance.
A malfunctioning E90 oil level sensor could give either high or low oil level readings. This could lead to over-filling or under-filling the oil level. This not only affects engine performance but also creates some serious issues like engine overheating, strange noises, or even engine breakdown.
One should not even think about this. Yes, problems with an oil level sensor can affect the overall engine performance. For instance, if a sensor gives false low readings, it can cause the driver to add more oil than is needed, resulting in over-oiling. On the other hand, if the sensor gives false high readings, the driver may not add enough oil, leading to low oil levels and eventual engine damage.
