Abstract

The invention belongs to the field of sensors, particularly relates to a water level sensor, and aims to solve the problems that an existing water level sensor cannot guarantee the levelness of a detection surface, is poor in structure sealing performance, inconvenient in terminal installation, unadjustable in wiring tightness and low in sensor disassembly and assembly flexibility and assembly precision. The invention provides the following scheme that the water level sensor comprises a base plate. A sleeve rod is vertically welded between the middle positions of the upper surface and the lower surface of the base plate, a gasket is fixedly installed in the middle position of the upper surface of the base plate, a fixing block is welded to the upper surface of the gasket, a clamping columnis welded to the lower surface of the sleeve rod, a column sleeve is movably installed on the sleeve rod through the clamping column, and an inner threaded sleeve is welded to the lower surface of the column sleeve. According to the invention, the water level sensor can guarantee the level of the detection surface to improve the accuracy of water level detection, the sealing performance of the structure is good, the terminals are convenient to install in the wiring area and can be adjusted in tightness, and the disassembly and assembly flexibility and assembly accuracy of the sensor are high.

Description

technical field [0001] The invention relates to the field of sensors, in particular to a water level sensor. Background technique [0002] The water level sensor moves vertically along the sleeve rod based on the buoyancy of the floating ball. When the magnet in the floating ball interacts with the reed switch at the corresponding height, the reed switch closes to change the resistance value of the series circuit and adjust the output voltage. It is widely used to detect water level. [0003] When the existing water level sensor is in use, it cannot be placed vertically, resulting in being unable to keep perpendicular to the highest surface of the water level and affecting the accuracy of water level detection. The poor sealing of the structure makes the internal circuit structure easy to be damp and short-circuited, which affects the water level detection. The smooth progress of the terminal installation in the wiring area is inconvenient and cannot be adjusted tightly, re...
