Liquid Water Multipoint Float Level Sensor Transmitter Gauge

Description 

The multipoint float level sensor transmitter gauge for liquid water – level switch is a liquid – level controller with safety, reliability, convenience for use and simple structure. One product can achieve multi – point control. It is characterized by long service life, fast speed and strong anti – load impact ability. The multipoint float level sensor transmitter gauge for liquid water – level switch is applicable to controlling the operation of pumps to maintain liquid levels, controlling the automatic loading and unloading of tanks, and controlling liquid levels or providing signals, such as in oil tanks, automatic cleaning systems, hydraulic tanks, low – pressure boilers and sewage treatment systems.

Features

• Multi – point control can be achieved. The position of the control switch can be customized according to the user’s requirements.

• Using a magnetic switch does not require a power supply, and the contact life can reach 2 million times.

• All switch output wires are in the same junction box, and the cost of external construction wiring is low.

• Compared with other forms of liquid – level switches with multiple switch control points, the unit price of the RF type is low.

• The protection level of the junction box is above IP65.

• There are PP and SUS316 metal materials, so suitable products can be used for any acid – base solution, solvent, or various fuel oils.

• The magnetic switch and the wire are completely isolated from the liquid, so it can also be used on high – temperature and high – pressure equipment.

• The linkage – type floating – ball liquid – level switch assembly is suitable for high – temperature and high – pressure situations.

• The 60VA dry – contact reed switch can select normally – open or normally – closed through the installation position of the floating ball.

• The 316 SS floating ball, conduit, and installation interface are suitable for harsh environments.

• With a rotatable base seat convenient for electrical alignment adjustment (NEMA 4X) and a polypropylene outer casing.

• The length of the conduit and the size of the switch setting point can be customized.

Working Principle

Inside a closed metal or plastic pipe, one or more magnetic switches are installed. Then, the pipe is threaded through one or more hollow floating balls with built – in ring – shaped magnets. Using fixing rings, the floating balls are fixed within the relevant range of the magnetic switches. When the floating balls move, the magnets inside them attract the contacts of the magnetic switches to act, thereby controlling or indicating the liquid level.

Application

The multipoint float level sensor transmitter gauge for liquid water – level switch is widely used in industries such as wastewater/water treatment, shipbuilding,generator equipment, petrochemicals, food, electronics, dyeing and finishing, chemistry, rubber and plastics, hydraulic machinery, and chemical pharmaceuticals.
