Embodiment
As shown in Figure 1, photoelectric chemical slurry interface-measuring device of the present invention can detect the air in the tested container-supernatant interface, supernatant-precipitum interface simultaneously.Photoelectric chemical slurry interface-measuring device of the present invention comprises photoelectric sensor, gear train, control circuit and display unit.
The photoelectric sensor of described measurement mechanism is connected with spiral reel and gear train by signal wire, and the transmission of photoelectric sensor working power and transmission mechanism control signal is connected with probe power, control circuit and display unit by signal wire and an aviation plug.Power supply, control circuit and display unit are installed in the control box, and power supply is 12V.
Described photoelectric sensor is made of LED photoelectric tube and photosensitive triode, float, and photoelectric tube and photosensitive triode are installed in the sensor holder of sealing, and guide rail is installed on the sensor holder, and float can move up and down on guide rail.The light that photoelectric tube sends is emitted to the photoelectric detector receive window that is made of photosensitive triode that is installed in its opposite by windowpane.
Described ball cock device is a square organic glass box, in its bottom 4 inlet openings is arranged.
Described gear train is made of spiral reel, micromachine, code-wheel and frame, can drive the sensor oscilaltion.Code-wheel can export displacement signal to display unit.
Described interface-measuring device also is provided with control box, and start and stop button, liquid level display unit are installed on its panel of described control box, and inside is equipped with power supply and control circuit board.
Display unit comprises DC power supply circuit, control circuit, electric cabinet and operation display panel, and sensor is connected with control circuit circuit and 12V power supply by an aviation plug.
As Fig. 2, shown in Figure 3, photoelectric sensor circuit is made up of circuit such as the amplification of power supply opto-electronic conversion and control, sound and light alarms.
Wherein power supply is by transformer, and rectification silicon bridge, voltage regulation filtering partly constitute.The transformer output voltage is AC15V.Through the silicon bridge rectification, alternating current becomes pulse direct current, again through capacitor filtering, stablizes DC12V voltage by integrated regulator (7812) output and uses for The whole control system.
The Lights section is made up of high brightness LED and dropping resistor R1 branch road.The big I that changes resistance R 1 makes light emitting diode obtain burning voltage, guarantees that luminous intensity is constant.
Optoelectronic multiplex switch is by phototriode D2, and resistance potentiometer RP forms, and when light or unglazed the photograph are arranged on the D2, high and low variation will take place the voltage signal that takes out from the RP tap.
Amplification and on-off circuit are made up of phototriode and integrated switch.The signal voltage that takes out from the RP tap amplifies through phototriode.When this voltage during greater than setting value, integrated switch conducting, relay J gets electric adhesive and drives executive component work.When voltage during less than setting value, integrated switch disconnects, the J dead electricity, and control circuit disconnects.
Because supernatant is very approaching to the change in electric and the air of refraction (absorption) generation of light, as not taking certain measure, will influence the reliability of instrument measurement.For this reason, increased by a cover ball cock device for sensor design.
When measuring, start gearing, sensor is descended, when sensor arrives the supernatant liquid level, receive buoyancy, float rises and blocks light source, make sensor signal voltage less than setting value, integrated switch disconnects, and gearing quits work, and scrambler changes the displacement dress into height that altitude signal demonstrates supernatant simultaneously.Start gearing once more, sensor continue to descend, and at this moment liquid enters float by the hole on the float and makes its whereabouts no longer can block light source.Sensor descends when arriving slurry interface, and this medium changes less than setting value the signal voltage of the absorption generation of light, and integrated switch disconnects, and gearing quits work, and scrambler changes the displacement dress into height that altitude signal demonstrates slurry interface simultaneously.
