How to apply a level sensor in an electric forklift?

- Jan 14, 2020-

Forklifts are industrial handling vehicles, which refer to various wheeled handling vehicles for loading, unloading, stacking, and short-distance transportation of palletized goods. The International Organization for Standardization ISO / TC110 is called an industrial vehicle. Commonly used for the transportation of large items in storage, usually using a fuel engine or a battery.

In terms of social benefits, forklifts have now become the main force of warehousing and logistics. When we mention electric forklifts, we have seen its huge environmental protection advantages. In the future, new battery and charging technologies will make forklifts charge faster and more powerful, and due to the rapid development of various technologies such as electronic control, the design of electric forklifts will be more compact in the future, and safety performance will be faster than that of internal combustion forklifts.

As a key component of electric forklifts, the condition of forklift batteries is particularly interesting. Because the forklift battery is the sole source of power for the forklift, it directly determines whether the forklift can operate normally.

Forklift batteries are used as DC power sources for forklifts, tractors, trucks, underground mine locomotives and other equipment. They are widely used in airports, stations, ports, vegetable and fruit markets, and industrial and mining enterprise warehouses. The forklift battery is a battery exclusively for forklifts that operates with batteries. This is the battery built into the battery of the electric forklift. The accumulator is a kind of battery, and its function is to store limited electric energy and use it in a proper place. Its working principle is to convert chemical energy into electrical energy.


When the forklift battery is charged: Especially near the gasification stage, the electrical reaction is that the battery fluid is electrolyzed and the battery fluid is discharged from the pores of the battery plate, so the battery fluid level will rise. When the forklift battery is discharged: the battery liquid penetrates into the pores of the battery plate, so the battery liquid level will drop. For the maintenance of forklift batteries, check the electrolyte level frequently. Below the rated level, the battery life will be shortened. Too little electrolyte will cause the battery to generate heat and damage. Therefore, you must always pay attention to the use of the electrolyte.


Forklift battery level check is so troublesome, is there any good solution?


The following editors recommend several liquid level sensor switches, which are suitable for forklift battery electrolyte liquid level detection.

Features 

The level switch can detect almost all liquids, oils or water. Suitable for harsh environments, optional stainless steel mounting thread.

Forklift battery electrolyte is generally strong acid and alkaline. The FS-IR1903D PSU series photoelectric level sensor can detect almost all liquids. The sturdy stainless steel housing package allows it to work in harsh and harsh environments, which is very suitable for working under strong corrosion such as strong acids and alkalis. At the same time, it has high power output, can directly drive the load, and can be used for electrolyte level alarm.
