Embodiment Construction

[0035] exist figure 1 In the shown first embodiment, the cross-section of the beam 1 is T-shaped, and five holes are arranged on its vertical plate. figure 1 In the four holes on the left side of the center, four short shafts 2 are installed with interference connection, and four rotatable electrodes 3 are installed on the four short shafts. In the other hole, a bolt connection is installed. The fixed electrode 4, the electrode lead 5 passes through the electrode lead constraining structure 6, and then the pressure plate 7 is pressed on the beam at the end of the beam close to the circular metal mounting piece 8, between the beam 1 and the circular metal mounting piece 8 Directly welded together, there is a hole on the circular metal mounting piece 8, and an outlet pipe 9 is welded at the hole position, and the electrode lead 5 passes through the pressure plate, and then passes through the hole on the circular metal mounting piece and the outlet pipe to lead out .

Abstract

The invention relates to a resistance-type liquid level sensing device for measuring the liquid level height of conducting liquid in a liquid storage container, comprising a cross beam. The cross beamis provided with more than one horizontally placed short shaft (at a working position), the short shaft is provided with an electrode with one end provided with a circular installing hole, and the electrode is electrically insulated from the cross beam and can rotate around the short shaft to the length direction of the cross beam so that the liquid level sensor can be installed through an installing hole of an overflow vent pipe of the liquid storage container. The liquid level sensor does not need to change the liquid storage container in installation, is convenient to install and use, hasno sealing and insulation problem in liquid by only immersing the metal electrode into the liquid, long service life and high reliability and solves the problems of the inconvenient installation and the short service life of the prior liquid level sensor.

Description

technical field [0001] The invention relates to a resistance type liquid level sensing device, which is used for measuring the liquid level height of conductive liquid in a liquid storage container. Background technique [0002] In various fields such as daily life and industrial and agricultural production, a large number of various liquid storage containers are used, such as water towers and various water tanks, etc. There is also a water tank in the widely used solar water heater, in order to be able to control the liquid level of the liquid storage container , it is necessary to measure the liquid level of the liquid storage container. At present, there are many kinds of liquid level sensors on the market, such as resistive, capacitive, inductive and ultrasonic, etc. These sensors need to be installed on the shell of the liquid storage container or in the liquid storage container, which is inconvenient to install and the working environment of the sensor Also worse.
