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.
