Abstract
The utility model relates to the control switch of a level transducer. The light emitting diode of an infrared transmitter is connected with an optical signal modulator through an optical cable. The optical signal modulator is connected with an infrared sensor through an optical cable. The optical signal modulator is positioned on the outer shell of a level transducer. The infrared sensor amplifies an optical signal which is received and control the equipment. The infrared sensor emits an alarm signal by a vocal mode and an optical mode. The utility model has the advantages of simple principle of structure, safe performance, long service life, etc. The utility model can not be disturbed by environment.
Description
The utility model relates to a kind of level transducer gauge tap.
Signal with liquid level sensor passes to controlled circuit at present, be that the electronic circuit that utilizes electronic devices and components to form carries out the signal transmission, having the low baking temperature flower produces, when in requiring explosion-proof environment, using, have potential danger, cause fire easily, also exist simultaneously and be subject to outside electromagnetic interference, poor reliability, problems such as the easy aged deterioration of electronic devices and components.
The utility model purpose provides a kind of optical cable non-contact type level switch that utilizes luminotron and optical cable that the liquid level sensor signal is transferred to optical receiver by photomodulator and carry out switch control.
The utility model is made up of level transducer, infrared transmitter, optical signal modulator, infrared remote receiver, optical cable, the light emitting diode of infrared transmitter links to each other with optical signal modulator by optical cable, catoptron is installed in the modulator shell, the optical cable that links to each other with signal modulator inserts the receiving tube of infrared remote receiver, optical signal modulator is positioned on the shell body of level transducer, and aligns mutually with the float of level transducer or connect by magnetic or connecting link.
The utlity model has that structural principle is simple, performance is safe and reliable, be not subjected to characteristics such as environmental interference, long service life.
Accompanying drawing 1 is the utility model structural representation.
Below in conjunction with accompanying drawing the utility model is further described, structure of the present utility model and principle are to realize like this, the light emitting diode 1 of infrared transmitter links to each other by optical cable 2 light signal with optical signal modulator, catoptron 3 is installed in the optical signal modulator, catoptron can be prism or level crossing, optical signal modulator also inserts the receiving tube 4 of infrared remote receiver by optical cable, optical signal modulator is installed on the shell body of level transducer 5, the float of level transducer links to each other with the catoptron of optical signal modulator by connecting link, assigned address and optical signal modulator that float is responded to are fixed, like this when float floats to warning or display position, drive optical signal modulator, the light signal that infrared transmitter sends is transferred to infrared remote receiver by catoptron in the optical signal modulator and optical cable just, the receiving tube of infrared remote receiver passes to the electronic signal process circuit with this signal, and directly carry out sound, signals such as light show or other equipment and instruments are controlled, if the float-type liquid level sensor adopts induction structure, when floating along with the rising of liquid level to reach, float reports to the police or during assigned address that signal shows, magnetic on the float just with the reflector mount that is positioned at sensor optical signal modulator outward on magnetic align mutually, make the light signal of infrared transmitter give infrared remote receiver, and control automatically or sound after with this signal Processing by electronic circuit by the mirror reflects in the optical signal modulator, the light alarm indication.
The utility model is to thing position signal reaction and precise control, and sensitivity is specially adapted to the liquid level monitoring of chemical industry liquid level meter than electronic type signal transfer mode height and dependable performance, also can replace electrode-type liquid-level meter senior middle school's low-pressure boiler is controlled automatically.
