Abstract
The utility model provides a liquid level sensor with stable signals. Relates to the technical field of liquid level meters. Including changer, mounting flange, installation pole and probe, the probe is cylindric, and the pressure sensing piece of probe is located the excircle surface of cylindric, and processing has one section screw thread post on the installation pole, screw thread post threaded connection flotation pontoon, an arc of flotation pontoon lower part fixed connection, and the arc inboard bonds has clean cotton, clean cotton inboard and the laminating of probe excircle. The utility model has the following beneficial effects: the float bowl floats up and down along with the change of the liquid level, and simultaneously rotates around the threaded column, so that the pressure sensing piece of the probe is cleaned, impurities and fungus adsorbed on the pressure sensing piece are cleaned, the sensitivity of the pressure sensing piece is recovered, the stability of the liquid level signal is maintained, and manual cleaning is not needed.
Description
Technical field:
the utility model relates to the technical field of liquid level meters, in particular to a liquid level sensor with stable signals.
The background technology is as follows:
the liquid level sensor is based on the principle that the measured hydrostatic pressure is proportional to the height of the liquid, corresponding liquid level data are calculated by detecting the water pressure with a specific depth, and when the traditional liquid level sensor is installed in a water tank or a water pool for use, particularly when the traditional liquid level sensor is installed in a sewage pool, impurities and bacteria growing in water can be adsorbed on a probe, so that the sensitivity of a pressure sensing sheet of the probe is reduced, and a liquid level signal is unstable.
The utility model comprises the following steps:
in order to solve the problem that a traditional liquid level sensor is unstable in signals in a sewage environment, the utility model provides a liquid level sensor with stable signals.
The technical scheme of the utility model is as follows: the utility model provides a signal stabilization's level sensor, includes changer, mounting flange, installation pole and probe, and the probe is cylindric, and the pressure sensing piece of probe is located the excircle surface of cylindric, and processing has one section screw thread post on the installation pole, screw thread post threaded connection flotation pontoon, an arc of flotation pontoon lower part fixed connection, and the arc inboard bonds there is clean cotton, clean cotton inboard and the laminating of probe excircle.
The cleaning cotton is made of chemical fiber materials, and the cleaning cotton is made of hydrophobic materials.
The pontoon and the arcuate sheet are made of plastic.
The utility model has the following beneficial effects: the float bowl floats up and down along with the change of the liquid level, and simultaneously rotates around the threaded column, so that the pressure sensing piece of the probe is cleaned, impurities and fungus adsorbed on the pressure sensing piece are cleaned, the sensitivity of the pressure sensing piece is recovered, the stability of the liquid level signal is maintained, and manual cleaning is not needed.
Description of the drawings:
FIG. 1 is a schematic diagram of the structure of the present utility model;
FIG. 2 is a section A-A of FIG. 1.
In the figure, the device comprises a 1-transmitter, a 2-probe, a 3-mounting rod, a 4-mounting flange, a 5-threaded column, a 6-pontoon, a 7-arc plate, an 8-pressure sensing sheet and 9-cleaning cotton.
The specific embodiment is as follows:
the utility model is further described below with reference to the accompanying drawings:
the utility model provides a liquid level sensor that signal is stable, including changer 1, mounting flange 4, installation pole 3 and probe 2, probe 2 is cylindricly, and the pressure sense piece 8 of probe 2 is located cylindric outer round surface, and processing has one section screw thread post 5 on the installation pole 3, screw thread post 5 threaded connection flotation pontoon 6, an arc 7 of flotation pontoon 6 lower part fixed connection, arc 7 inboard bonds has clean cotton 9, clean cotton 9 inboard and the laminating of probe 2 excircle.
The cleaning cotton 9 is made of chemical fiber materials, the cleaning cotton 9 is made of hydrophobic materials, the stability is high, and bacteria are not easy to breed.
The pontoon 6 and the arcuate sheets 7 are made of plastic.
The pontoon 6 floats up and down along with the change of the liquid level, and meanwhile, the pontoon 6 rotates around the threaded column 5, the cleaning cotton 9 wipes the pressure sensing piece 8 of the probe 2, impurities and fungus adsorbed on the pressure sensing piece 8 are cleaned, the sensitivity of the pressure sensing piece 8 is recovered, the stability of a liquid level signal is maintained, and manual cleaning is not needed.
