Abstract
The utility model relates to a magnetic float flap liquid level transducer which comprises a buoy (1) containing liquid and a dry reed tube sensor (3) and a transducer (4) mounted on the buoy (1), wherein the dry reed tube sensor (3) is electrically connected with the transducer (4), a magnetic float (2) is arranged on the surface of the liquid in the buoy (1), the magnetic float (2) floats on the surface of the liquid, and one side of the magnetic float (2) is near to a dry reed tube switch (3-1) of the dry reed tube sensor (3). The magnetic float flap liquid level transducer has no measurement blind zones, leads the detection to be very convenient, improves the degree of automation, reduces the manpower and saves the cost.
Description
Technical field
The utility model relates to a kind of magnetic float turnover panel fluid level transmitter, belong to a kind of liquid level instrument, be used for oil, chemical industry, electric power, food and pharmaceuticals industry, container medium liquid levels such as various towers, jar, groove, case and underground tank are carried out the teletransmission of signal, be used for remote monitoring.
Background technology
In the prior art various towers, jar, groove, case liquid level are carried out the signal measurement teletransmission, usually adopt ultrasonic level gage, but mostly now good jar, groove, case are sealing, highly less than is one meter, ultrasonic level gage is installed needs certain space, and also there is the blind area of 0.3m in ultrasonic level gage, is not easy to measure.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of the existence to measure blind area, the magnetic float turnover panel fluid level transmitter that automaticity is high.
The technical scheme that realizes above-mentioned purpose is: a kind of magnetic float turnover panel fluid level transmitter, comprise the floating drum that fills liquid, be installed in tongue tube sensor and transmitter on the floating drum, tongue tube sensor and transmitter are electrically connected, liquid surface in the floating drum is provided with magnetic float, magnetic float floats on the liquid surface, and a side of magnetic float is near the dry-reed tube switch of tongue tube sensor.
After adopting technique scheme, magnetic float is housed in the floating drum, magnetic float goes up with liquid level together when liquid level rises, and the adhesive tongue tube changes resistance because float is magnetic, and calculates current signal with the transmitter that the tongue tube sensor electrical is connected according to ohmer, supplying with distant place control gathers, do not exist and measure the blind area, detect very conveniently, and improved automaticity, reduce manpower, saved cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of dried spring sensor among Fig. 1;
Fig. 3 is circuit theory diagrams of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
Shown in Fig. 1～3, a kind of magnetic float turnover panel fluid level transmitter, comprise the floating drum 1 that fills liquid, be installed in tongue tube sensor 3 and transmitter 4 on the floating drum 1, tongue tube sensor 3 and transmitter 4 are electrically connected, liquid surface in the floating drum 1 is provided with magnetic float 2, and magnetic float 2 floats on the liquid surface, and a side of magnetic float 2 is near the dry-reed tube switch 3-1 of tongue tube sensor 3.
The tongue tube that the utility model adopts is a kind of passive electronic on-off element that the contact is arranged, have simple in structurely, volume is urinated in advantages such as controls, and its shell generally is a sealed glass pipe, the elastic spring electroplax of two ironys is housed in the pipe, and also irritating has a kind of inert gas that is metal rhodium.At ordinary times, two reeds of being made by special material in the glass tube separate.When the glass tube, under the effect of magnetic field magnetic line, two reeds in the pipe are magnetized and the contact of attracting each other as magnetisable material, and reed will be pulled together, the circuit communication that node is connect.After outer magnetic force disappeared, two reeds were owing to the elasticity of itself is separated, and circuit has also just disconnected.According to its characteristics attraction circuit, change resistance value.
As shown in Figure 3, transmitter circuit is typical serial regulating circuit making alive series connection negative-feedback circuit, circuit totally is divided into 2 parts, a part is a prime 4mA circuit, two stabilivolt Z3, Z7 are arranged, resistance R 3, R2,4mA circuit utilization LM317 stabilized voltage supply, also given simultaneously a reference source of late-class circuit amplifier, imitated 4mA signal at accurate zero point by R21.Another part is a back level 16mA circuit; late-class circuit is by detecting liquid Z3, Z7, R3, R1, C1; the resistance value that the liquid level rise and fall change is converted to voltage signal; with amplifier small voltage change signal being amplified the back comes Control current for the base stage of triode; negative feedback has more increased the stability of circuit; circuit is imitated accurate full scale 20mA signal with R22, has polarity to connect anti-protection.
Principle of work of the present utility model is as follows:
Floating drum is equipped with magnetic float 2 for 1 li, magnetic float 2 goes up with liquid level together when liquid level rises, the adhesive tongue tube changes resistance because float 2 is magnetic, and the transmitter that is electrically connected with tongue tube sensor 34 is calculated current signal according to ohmer, supplies with distant place control collection.
Claims (1)
1. magnetic float turnover panel fluid level transmitter, comprise the floating drum (1) that fills liquid, be installed in tongue tube sensor (3) and transmitter (4) on the floating drum (1), tongue tube sensor (3) and transmitter (4) are electrically connected, it is characterized in that: the liquid surface in the floating drum (1) is provided with magnetic float (2), magnetic float (2) floats on the liquid surface, and a side of magnetic float (2) is near the dry-reed tube switch (3-1) of tongue tube sensor (3).
