Measuring Principle
A float guided on a non-magnetic tube follows the level of the liquid surface, thereby actuating the reed switches located inside the tube by means of a built-in magnet system. The reed switches shunt over parts of a resistor string. The magnet system operates the reed switches according to the position of the float and thus causes the resistance of the resistor string to change as a function of the liquid level. The float travel distance can be limited by stops fitted to the guide tube. The signal conditioner produces an output signal from 4 – 20 mA.
