Abstract
The utility model relates to an inductive float liquid level switch which belongs to industrial automation devices, particularly liquid level switches. The liquid level switch is characterized in that the upper position and the lower position of a barrel body are respectively provided with an upper limit position sensor and a lower limit position sensor, and the barrel body is provided with a guiding hole. A connecting rod connected with a floating ball passes through the guiding hole, and the position on the connecting rod between the upper limit position sensor and the lower limit position sensor is provided with a triggering sheet. The utility model has the advantages of simple structure, high precision, realization of the upper and lower limit detection of liquid level and simple installation.
Description
Technical field
The utility model belongs to industrial automation arrangement, particularly liquid-level switch.
Technical background
Traditional liquid-level switch has machinery lever-type, dry-reed, and both certainties of measurement are all lower.After mechanical contact service time was long slightly, action is malfunctioning and poor contact of contacts easily, and error is bigger; Though the detection error of dry-reed is slightly little, its upper and lower limit position is not easy accurate measurement, uses inconvenience.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of induction type float liquid level switch, and it is simple in structure, and the precision height can realize that the liquid level upper and lower limit detects, and installs simple.
Solving the scheme that technical problem of the present utility model adopts is: the upper and lower limit position transducer is equipped with at the upper and lower position at a cylindrical shell respectively, have pilot hole on the cylindrical shell, the connecting rod that is connected with ball float passes pilot hole, in the position between the upper and lower limit position transducer on the connecting rod shake-up sheet is housed.
This liquid-level switch is mainly used in the detection of open type liquid level, its measuring principle is: when liquid level rises or descend, ball float is under the synergy of buoyancy or gravity, directly drivening rod is done vertical moving up and down, when touching sheet near upper limit sensor or lower limited sensor, the transducer action and the output signal of telecommunication, when the shake-up sheet left, transducer stopped to export the signal of telecommunication.The distance of upper and lower limit can be by adjusting the set positions of upper and lower limit transducer.Whole device can be dismantled, and packing and installation are all very convenient.Because of having adopted inductosyn, the distance of upper and lower limit is adjustable again, so precision is higher, is very suitable for as the control system detecting instrument.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Each label is represented successively among the figure: tighten and cover 1, main cylinder 2, middle connecting rod 3, down fastening cover 4, regulate bolt 5, connector 6, lower link 7, ball float 8, lower position transducer 9, mounting blocks 10, touch sheet 11, upper limit position transducer 12, go up connecting rod 13.
Embodiment
Referring to Fig. 1, the structure of this device is, upper and lower end at main cylinder 2 is installed extreme position transducer 12 and lower position transducer 9 by regulating bolt 5, directly adjusting adjusting bolt 5 just can make the position of transducer change, the adjustment space of upper limit position transducer 12 and lower position transducer 9 is left at the two ends that will tighten and cover 1, fastening cover 4 are loaded on main cylinder 2 respectively down at fastening cover and 2 of main cylinders.Main cylinder 2 and tightening covers 1, the center of having becomes collinear pilot hole on the fastening cover 4 down, and the connecting rod that is connected with ball float 8 passes pilot hole, makes the motion of connecting rod keep vertical.Connecting rod is divided into 7 three sections on connecting rod 13, middle connecting rod 3, lower link, adopts threaded connector 6 to be connected into whole one section, touches on the connector 6 that sheet 11 is loaded on 3 on connecting rod 13 and middle connecting rod.
Claims (3)
1, a kind of induction type float liquid level switch, it is characterized in that the upper and lower limit position transducer being housed respectively at the upper and lower position of a cylindrical shell, have pilot hole on the cylindrical shell, the connecting rod that is connected with ball float passes pilot hole, in the position between the upper and lower limit position transducer on the connecting rod shake-up sheet is housed.
2,, it is characterized in that the upper and lower limit position transducer all is contained on the cylindrical shell by regulating bolt by the described induction type float liquid level of claim 1 switch.
3, by the described induction type float liquid level of claim 2 switch, the upper and lower end that it is characterized in that cylindrical shell is connected with upper and lower fastening cover respectively, connecting rod is divided into three sections of upper, middle and lower, is connected into whole one section with connector, touches sheet and is loaded on the connector between connecting rod and middle connecting rod.
