Abstract
The utility model relates to a liquid level probe, belonging to technical field of device for detecting change of liquid lever in a container. The utility model detects the change of the liquid level in a container, in particular to a liquid level probe. As the prior water blocking type liquid sensor or the magnetic branch type sensor is affected by deposited scale, thus being poor in reliability and having dead signal. The technical proposal of the probe is that: a metal tube 1 is connected to an electrode lead 4 through a pad 3 and the outer of the metal tube 1 is coated with an insulated medium layer 4. The advantages of the utility model are that: water and a metal conductor do not compact; scale has no damage to the utility model and never requires maintenance; at the same time, the water has no electricity, thereby the utility model is reliable to provide continue signals and precise collection.
Description
(1) technical field: the utility model relates to the Element Technology field that the level change in the container is surveyed, and is a kind of Liquid level probe more specifically.
(2) background technology: the measurement that liquid level position is changed at present, particularly the measurement to the solar water heater water level is to adopt water resistance type level sensor or magnetic float-type transmitter, preceding a kind of shortcoming is: the bare metal position is arranged above the probe, resistance becomes very big when the water fouling, cause signal malfunctioning, reliability greatly reduces; The back is a kind of to make float slip be obstructed when the water fouling influences reliability.
(3) summary of the invention: the purpose of this utility model is a kind of Liquid level probe of design, owing to its metal tube is surrounded by insulating medium layer outward water is not contacted with metallic conductor, thereby has fundamentally overcome above-mentioned shortcoming.Its technical scheme is: metal tube 1 is connected with contact conductor 4 by pad 3, the metal tube 1 outer insulating medium layer 2 that is surrounded by.The advantage of this probe is: novel ingenious, water does not contact with metallic conductor, is not afraid of incrustation scale, never maintenance; The nothing electricity is reliable and secure in the while water, and signal is accurate with collection continuously, and low cost of manufacture is easy to utilize.
(4) description of drawings: this accompanying drawing is the utility model structural representation.In the accompanying drawing: 1, metal tube, 2, insulating medium layer, 3, pad, 4, contact conductor.
(5) embodiment: metal tube 1 is connected with contact conductor 4 by pad 3, the metal tube 1 outer insulating medium layer 2 that is surrounded by.This probe is inserted in the liquid, isolate the variable capacitance that forms with SEA LEVEL VARIATION by insulating medium layer 2 between metal tube 1 and the liquid, electric capacitance change when liquid level change, cause the electromagnetic oscillation frequency change with the supporting outer transmitter of this probe, convert the curtage signal output of variation again to.
Claims (1)
1, a kind of Liquid level probe is characterized in that: metal tube (1) is connected with contact conductor (4) by pad (3), the outer insulating medium layer (2) that is surrounded by of metal tube (1).
