KROMA liquid level switch working principle introduction

Germany KROMA liquid level switch, also known as water level switch, Germany KROMA liquid level sensor, as the name suggests, is the switch used to control the liquid level. Formally divided into contact and non-contact. Commonly used non-contact switches have capacitive liquid level switches, and contact float type liquid level switches are the most widely used. Electrode type liquid level switch, electronic liquid level switch, capacitive liquid level switch can also be realized by contact method.
The magnetic float of the float ball level switch rises or falls with the liquid level, so that the sensor detects the position of the reed switch chip in the tube, and sends a contact opening (off) switching signal.
One or more reed switches are installed in the closed non-magnetic tube, and then the tube is passed through one or more floating balls with hollow magnets inside, and the rise or fall of the liquid will move the floats up and down together. Thereby, the reed switch in the non-magnetic tube generates an action of sucking or breaking, thereby outputting a switching signal.
KROMA float switch is a liquid level control device with simple structure, convenient use, safe and reliable. It has smaller volume, faster speed and longer service life than general mechanical switch. Compared with electronic switch, it has anti-load impact capability. Strong characteristics, it has been widely used in shipbuilding, papermaking, printing, generator equipment, petrochemical, food industry, water treatment, electrician, dye industry, hydraulic machinery and so on.

Germany KROMA float switch
The German KROMA float ball level switch uses a micro switch to make the contact output. When the angle above the horizontal plane exceeds 28°, the steel ball inside the German KROMA float level switch will roll to the micro switch or leave the micro switch to make the contact signal of the liquid level switch ON or OFF output.

There is also another type of float ball level switch, which uses the mercury switch as the contact output. When the liquid level rises to contact the float ball, the float ball changes with the height of the water level as the center of the weight. When the angle above the water surface exceeds 10°, the liquid level switch will have an ON or OFF contact signal output.

The main features of the German KROMA float switch:
1. Use the micro switch to make the contact output. The contact capacity of 10A/250VAC can directly start the motor equipment.
2, European standard (HAR) rubber cable, good weather resistance, low price and long service life.
3, the structure is simple, no maintenance, sewage water can be used.
4, the length of the cable ≦ 20 meters can be customized.
