Problems solved by technology

In the prior art, there is no special detection equipment for its detection. It is just a simple test that the water level sensor outputs a signal to drive the buzzer when it is powered on for self-test, and the self-test time is detected by hearing and the buzzer rings. Judging the output voltage of the sensor, the measurement data is not intuitive and extremely inaccurate, resulting in a low pass rate of products sold, which is easy to be returned or fined, causing certain economic losses for the manufacturer

Abstract

The invention discloses a detector for a fuel oil filter water level sensor. The detector comprises an indicator light, a wiring terminal, a display, a switch and an internal circuit module, wherein the indicator light, the wiring terminal, the display and the switch are arranged on an instrument panel. When the water level sensor is connected, the corresponding internal circuit module triggers a timer to display self-inspection time, an output voltage display displays the real-time output voltage of the water level sensor, and meanwhile the self-inspection time is kept all the time till the water level sensor is pulled up. After self-inspection is completed, the electrode of the water level sensor meets water, a counter used for displaying water-meeting delayed alarm time displays the water-meeting delayed alarm time, and the output voltage display displays the real-time output voltage of the water level sensor. In this way, various performance parameters of the water level sensor can be detected accurately and visually, and the performance parameters include the self-inspection time, the water-meeting delayed alarm time, the output voltage and current and the like; the problem that a self-inspection time judging mode by means of auditory sense before is not visual and accurate is changed thoroughly.

Description

technical field [0001] The invention relates to the field of automotive electronics, in particular to a diesel oil filter water level sensor detector. Background technique [0002] Diesel filter water level sensor is a new type of automotive electronic product. Its main performance parameters include the self-test time of the sensor when it is powered on, and the output voltage when it alarms. In the prior art, there is no special detection equipment for its detection. It is just a simple test that the water level sensor outputs a signal to drive the buzzer when it is powered on for self-test, and the self-test time is detected by hearing and the buzzer rings. Judging the output voltage of the sensor, the measurement data is not intuitive and extremely inaccurate, resulting in a low pass rate of products sold, easy to be returned or fined, causing certain economic losses for the manufacturer. [0003] Therefore, there is an urgent need to provide a device for detecting the ...
