Side mounted float level controller

Productoverview:

ZW-UQK series Side mounted float level controller Through the magnetic induction induction to achieve level, level role.The floating ball is equipped with a magnet, and the plastic float level switch body which equipped with imported dry reed or reed switch, dry reed pipe connected with the two lines, usually removed in the plastic body or body is 350MM stainless steel. The dry reed pipe of high temperature or low temperature white black adhesive glue injected in the body.

Two, work principle:

ZW-UQK series side mounted float level controller is composed of isolated float group and contact group is composed of two parts. When the liquid level is increased or decreased, the floating ball 1 come down the end of the magnet 2 swing up and down, through magnetic force, repulsion mounted in the housing 3 in the same pole magnet 4 swing up and down, the other end of the movable contact 5 is 1-1 and 2-2 in the static contact or connectivity disconnect. The liquid has buoyancy, and the float system (generally have the corresponding auxiliary equipment) is based on the liquid buoyancy and supporting the production, when the liquid level rises, float system is rising, so when the liquid level drops also decreased, when the rise or fall to the set position, floating the ball is in the system will meet the travel switch set position (or other microelectronic devices), so that the switch sends electrical signals, and the electronic control device will immediately after receiving the action signal, cut off or connected to the power supply, automatic control system formation.

Three, application:

ZW-UQK series side mounted float level controller is suitable for all kinds of industrial equipment, household appliances and other oil and water machine. Stainless steel floating ball liquid level switch for liquid level detection, all kinds of small and medium pressure and pressure of liquid storage tank remote signal, alarm switch, can be applied to a variety of health, environmental protection, poisonous and corrosive medium with strong acid liquid.Home appliance or mechanical and PP plastic floating ball is mainly used in hot water, such as water heaters, water machine, dishwasher, electric water heater, hydraulic machine, air compressor, and other ancillary equipment.

Four, main features:

1. can be installed on the level of the tank wall, also can be installed on the vertical tank top;

2. has the advantages of simple structure, reliable performance, convenient installation;

The 3. control part and the measured liquid medium is completely isolated, with the use of high temperature and high pressure environment;

4. material, connection mode can meet the needs of different environment;

5. a wide range of applications: food, medicine, chemical, electronics, shipbuilding, water treatment and other industries,

Five, technical parameters:

1, rated current: 16A-120VAC; 10A-300VAC; 0.6A-150VDC;

2, an independent contact output: SPDT contact;

3, contact material: silver (Ag);

4, body material: precision alumina ceramics;

5: die casting magnesium alloy shell, switch surface polishing of polyurethane coating;

6, the rated temperature: Standard Type: -40~250 ~ C;

7, high temperature type: 370 ~ C;

8, pressure rating: ANSI Class150 and 300, 600, 900LB, PN1.0;

9, process connection: flange connection, 80 DN50, 100 2'~4 ANSI; ";

10, medium density: 0.40g/cm3;

11, electrical interface: M20 * 1.5, 1/2'NPT female;

12, flameproof explosion-proof grade: Exd II BT4 II CT6 Exia intrinsically safe;

13, protection grade: IP65.

Six, installation method:

1, the installation should be far away from the inlet (outlet) nozzle, so as to avoid water fluctuations caused by misoperation;

2, installed in the mixing area, can be installed at the tube or baffle;

3, junction box line inlet to down;

4, the control circuit load does not overload use (less than the capacity of contact use);

5, the floating ball and the connecting rod to move up and down the angle (horizontal line) to + 14 degrees, when the floating ball in the horizontal position switch;

6, the installation should pay attention to and the connecting pipe length and aperture size matching, to ensure that the floating range of the floating ball.

Note: the total length of the floating ball and a connecting rod part to allow a certain degree of error.

Seven, the nature of the liquid medium and float relationship:

1, the liquid proportion does not change at the same time, action position will float, generally higher than water hours, the floating ball dipped in the liquid part will be relatively increased.

2, the proportion of float switch product reference with water (SG=1) so when used in the selection of the floating ball must be considered when the liquid level is greater than the proportion of floating ball size indicated, otherwise, the float switch can not float.

3, high viscosity liquid will not dry, should generally be used for large diameter floating ball.

4, the float switch is used to sense the magnetic reed switch, the liquid level should therefore be free of iron, otherwise it will affect the correct action team floating switch.

Eight, selection description:

Please use the measured object in accordance with the characteristics of temperature, pressure, density, acid and alkali, the list of various specifications of the floating ball.

1, PVDF high temperature: the temperature of 120 DEG PPzui, 80 C, 200 c SUS304/316.

2, pressure: plastic floating ball pressure Zui 5kg/cm2 SUS float voltage 30kg/cm2.

3, adhesion: floating ball, the ball should be used to overcome the small proportion of liquid surface tension.

4, of plastic material is suitable for the places such as temperature pH, consideration should be used in PVDF.

5, oil: the use of metal materials.

6, the proportion of floating ball: the proportion of SG must be less than the measured liquid, or float float.

7, voltage: 220VAC current: 0.7A.

Nine, matters needing attention:

1, the length can be set by the user.

2, the control points can do one or two.

3, the control points can be N.O. or N.C.

Note:

In 1, does not affect the original function of the product principle, the company has the right to modify the product appearance, color, size and internal structure, products such as change without notice.

2, mini float level switch in - 5mm within the total length of all belong to normal tolerances.

Ten, specification data sheet:

Eleven, The selection of encoding:

Note: Please specify the specific process of connection, the size and position of action point.

Twelve, design selection and ordering information:

1, liquid level switch device specifications;

2, measuring range;

3, working pressure and temperature;

4, material control device;

5, the special requirements of negotiation;
