LEVEL SWITCHES

LEVEL SWITCHES (SOLID) MEMBRANE

The level switch consists of a microswitch inside a plastic box, covered by a flexible membrane.

The device must be mounted so that the flexible membrane is exposed to the product whose level should be controlled, in such a way that the product, if present, can press the membrane. When this membrane becomes covered up by the product, it moves under the product pressure, thereby working the microswitch. The device must be connected to control signals or to mechanisms driving the product transportation systems, like feeding, unloading, etc.

The level switch is used for indicating, controlling, and regulating the level of granulated or powdered dry materials with a grain diameter up to 30 mm and a density of 0,3 to 2,5 g/cm3, flowing through a silo, hopper or conduit.

LEVEL SWITCHES (SOLID) ROTARY PADDLE SWITCH

The level switch is used for indicating, controlling, and regulating the level of granulated or powdered dry materials with a grain diameter up to 15 mm flowing through a silo, hopper or conduit.The device specially detects the presence or absence of product at its level.
It consists of a synchronous low speed motor reducer, which is closed inside a fibreglass reinforced plastic box, and whose shaft drives a stainless steel blade rotating outside the box.

The synchronous motor reducer with low speed and small torque, drives the stainless steel blade which should have been mounted so that it can rotate free inside the container when no product therein. In this situation, the microswitch inside the box supplies a given signal to the output circuit. When the product to be controlled reaches the level of the rotating blade inside the container, this blade is permanently stopped, making the microswitch position to change over and reversing the signal from the output circuit.
When the rotating blade it is free of product, it beguin to rotate, reversing again the signal in the output circuit.
