TECHNICAL FIELD

[0001] The utility model relates to the field of sensor, especially a kind of oil circuit fault detection sensor. BACKGROUND

[0002] Oil circuit fault detection sensor is a kind of sensor equipment specially used for monitoring and detecting potential faults in oil circuit system. In the oil circuit system of vehicle or machine, these sensors can monitor the pressure, temperature, flow, oil level and quality of oil product and other key parameters of oil circuit in real time. When these parameters exceed the preset normal range, the sensor will issue an alarm to remind the driver or maintenance personnel to pay attention and take appropriate measures to prevent or solve potential faults. The working principle of oil circuit fault detection sensor usually involves converting physical or chemical parameters in oil circuit into measurable electrical signals. These electrical signals are then transmitted to the control system or monitoring equipment of vehicle for further analysis and processing.

The patent records the technical scheme of "connecting the device with the oil pipe, the oil enters through the oil inlet and is discharged through the oil outlet. During use, the pressure oil in the pipe enters the movable groove through the oil inlet. Under the action of oil pressure, the movable groove and the push rod move to the right, simultaneously extruding the spring, until the oil outlet is opened and connected with the sealing groove. Under the continuous supply of pressure oil, the oil inlet and the oil outlet remain connected.
