This sensor is used to monitor the oil level by continuously measuring the engine oil level in the static and dynamic ranges. The sensor is designed for vertical installation from below in the bottom of the oil pan. Inside the housing there are the level sensor, temperature sensor, and sensor electronics. Oil sensors in the vehicle ensure that the engine does not run unnoticed with too little oil. The proven technology of ultrasonic sensors utilizes the runtime principle and monitors the level continuously during the travel. When the engine is running (dynamic range), the level is noticeably lower than the level at standstill (static range). A dipstick checks the oil level only in the static range in mobile engines. This oil level sensor is able to measure the oil level continuously, i.e. both in the dynamic and static ranges. It thus provides information about the oil level during the entire engine operation, which, in construction machinery, tractors and forklifts, may often take several hours.
