Flexible circuit film engine oil sensor |
摘要 |
A flexible circuit film oil sensor includes a flexible circuit film surrounded by a flexible border. A core support flap and a weld flap are attached to opposite ends of the flexible border. The flexible circuit film includes an oil level sensing electrode surface, an oil condition sensing electrode surface, a resistive temperature device, and a common electrode surface. The flexible circuit film engine oil sensor is wrapped around a core structure so that a spiral oil chamber is formed. Accordingly, the spiral oil chamber is at least partially filled with oil and electrical signals are provided across the electrode surfaces in order to monitor the level and condition of oil within the sensor. Additionally, the resistive temperature device provides a signal representative of the temperature of the oil within the sensor.
