Spherical level switch use and scope of use
The spherical liquid level switch (hereinafter referred to as the switch) is mainly for the liquid level fixed-point communication, to achieve the alarm, control, regulation and other functions in the production process, in the production process of acid, alkali solution or water supply, drainage, chemical sewage treatment, etc. Indispensable tool, the main parts of the switch are made of 1Cr18Ni9Ti stainless steel, which has good corrosion resistance. Its characteristics are: economical and practical, reliable and versatile.
2, specifications and technical parameters
2.1 Off cable length: 4, 5, 6m (or a length proposed by the user)
2.2 Medium density:
2.3 Medium temperature: ≤100°C
2.4 Working pressure: 0.2MPa A normally open
2.5 Contact capacity: 220V AC 5A
2.6 Send two signals (one normally open, one normally closed)
3, liquid level switch structure principle and installation and use
3.1 The switch structure is simple and the structure is as follows
The switch housing is made of stainless steel sphere with smooth surface and not easy to adhere to dirt. It can be used in mixed sewage, mud, acid and alkali solution. The ball body is equipped with a large-capacity mercury switch. The mercury switch is connected to the soft cable and lengthened. Or shorten the cable length to get the desired water level.
3.2 The switch is suspended from the fixed rod. As shown in Fig. 2 (a), when the liquid level rises and the liquid level contacts the switch, the switch sphere is tilted under the action of buoyancy, as shown in Figure (b)b. The mercury switch in the switch ball is opened or closed to signal.
