Product Overview

OVERVIEW

 Principle:

■ The LDD series connecting rod float level switch is a liquid level controller that is safe, reliable, easy to use and has a simple structure. One product can achieve multi-point control. It is characterized by long life, fast speed and strong resistance to load impact.





Features

FEATURES




Features:

■ The LDD series connecting rod float level switch can be used for multi-point control, and the control switch position can be customized according to the user's needs.

■ No power supply is required to use a reed switch.

■ All switch outlets are in the same junction box, and the cost of external construction wiring is low.

■ Multiple switch control points compared to other types of liquid level switches.

■ The protection level of the junction box is IP-65

■ There are PVDF, PP, PVC plastic materials and SUS304, SUS316 metal materials, so regardless of acid and alkali liquids, solvents or various fuels, there are suitable products that can be used together.

■ The reed switch and the wire are completely isolated from the liquid, so it can be used safely on high-temperature and high-voltage equipment.


 Application Areas:

■ LDD series products are used for all kinds of clean liquids with density ≥ 0.55g/cm³. Such as wastewater/water purification treatment, shipbuilding, generator equipment, petrochemistry, food, electronics, dyeing and finishing, chemistry, rubber and plastics, hydraulic machinery, chemical pharmaceuticals and other industries.
