Abstract
The utility model relates to a probe rod of the insulated liquid level, which is provided with a conducting rod core 4. An insulation layer 5 is arranged outside the conducting rod core 4, and a metal sleeve 3 is arranged outside the insulation layer, which is fixed by a fixed bolt 2. The upper end of the metal sleeve is provided with a socket 1. The utility model has the advantages of simple structure, stable performance, long service life, not easy runaway and not easy generation of accidents. One probe rod can replace a plurality of electrode bars to probe the liquid level and is easy to be used by being matched with a digitizing circuit.
Description
The utility model relates to a kind of insulation liquid level detector bar that may detect liquid level high and low position in water tank, the boiler.
Prior art is the conductive liquid level detector bar, and it is to utilize with the electric conductivity of liquid level to control liquid level by electronic circuit, so exists electric current to flow in the detector bar (electrode bar), so there is electric Jie's phenomenon to exist, long-term use can make the detector bar corrosion and scaling, causes liquid level out of control, and is accidents caused.
The purpose of this utility model is the problem at above-mentioned existence, proposes a kind of new insulation liquid level detector bar.
Technical solution of the present utility model:
The center of rod is a contact rod core 4, and its periphery is one deck conduction insulation course 5, and the periphery of insulation course is a metal sleeve 3, and metal sleeve 3 is fixing by bolt 2, and the upper end of set bolt 2 is twin-core electrical sockets 1.
Advantage of the present utility model:
Because of dielectric protection layer being arranged so no current exists, continuous working need not be changed, and just with many electrode bars of a detector bar replacement, designs simplification, life-span are long, are convenient to and the supporting use of digital circuit.
Accompanying drawing 1 is a structural representation of the present utility model.
Further describe technical solution of the present utility model in conjunction with the accompanying drawings:
Contact rod core 4 in the metal sleeve 3 is to adopt insulating sheath or enameled wire to make, at its outer one deck insulation course that is with, detector bar can be unified into the variation that light beam is made the simulation liquid level with light emitting diode, metal sleeve 3 is fixing by bolt 2, there is socket upper end at metal bar, adopts the two-wire cable socket.This detector bar is owing to adopting dielectric protection layer, so its no current flows has overcome the existence of electric Jie's phenomenon.Detector bar is corroded, fouling with regard to effectively avoiding like this, and stifled having cut off by the accident that causes out of control taken place.Improved the stability of performance, prolonged serviceable life, realized replacing the purpose of many electrode bar control liquid levels, thereby made simple in structure, easy and the supporting use of digital circuit with a detector bar.
