The stainless steel float switches are more resistant to certain media (e.g. weak acids or alkalis) than the plastic mini float switches.The V4A stainless steel mini float is more resistant to corrosion in salt water and chlorine-containing media such as pool and swimming pool water. It is popularly used in chemical industry due to its resistant properties.
There is a ring magnet in the float, and a reed contact cast in Wepuran® in the shaft. If the float moves upwards, the reed contact is switched over. The shaft is milled and turned from solid V4A material and is correspondingly costly to manufacture. The stainless steel float switch is reliable, maintenance- and wear-free and easy to install.
The lower the voltages and currents, the more switching cycles are possible. According to Meder, 1 trillion switching cycles can be achieved if the switching power is kept below 5 volts and 1 mA, which applies to all water detectors from Elektrotechnik Schabus. Only Meder reed contacts are potted in the shaft to be waterproof. The contact switches on at a certain level and activates the input of the water detector.
As with all sensors and float switches from SCHABUS, it is also possible with this float switch to get the cable in desired length or other types. Talk to our technical support.
Useful accessories are the mounting bracket or the dirt trap incl. mounting bracket, which ensure that the mini float switch is mounted as vertically as possible with a deviation of max. 30°, so that the float can move freely on the shaft without jamming.
