Level switches

//Level switches

By float

It detects the level with a float. There are infinity of models, shapes and specific applications. Suspended floats. It is the easiest and most economical system for level control in tanks and wells. It is a float suspended in a cable that when reaches the water level it tilts its position by activating an internal microswitch. Currently all models are free of mercury. We have different cable lengths and materials. Magnetic switches for vertical installation. A magnetic float moves by an inmersor activating a contact (or several) situated in the indicated point(s). The fixing part of the top of the [...]

Multi-point

Level switches that are activated by the movement or magnetic floats that activate reed contacts with the magnetic field. There are many combinations from a single buoy that temporarily activates the contacts when passing them to several buoys where each one activates one or two contacts that are switched until the buoy returns to its initial state.  The devices with several floats facilitate the application because the level will be always reflected in the signal of the l microrruptor, avoiding problems arising from temporary activations of instability. We have several models, shapes and materials. The parts in contact with the [...]

Conductive

As its name indicates, it is applicable only to conductive fluids. It detects the increase of the conductivity of the absence of liquid (without conductivity) to the presence of it (an adjustable conductivity in the level control). It needs a minimum of two conductive points; The one corresponding to the electrode where the level point is and the other that will always be in contact with the fluid. A priori, we can install as many electrodes as wanted. This can be done by means of multi-electrode probes (up to 5 electrodes) or by independent electrodes situated in the top or [...]

Non-intrusive

Different operating principles (microwave, capacitance, etc.) allow us to detect liquid or solid (depending on model) through a wall of nonconductive material (plastics, fibres, glass). It is ideal for applications where it is not possible to install an element in contact with the product due to a compatibility problem of materials, tank construction, etc. In liquids application, in some cases the detector can be applied en un tubo lateral de nivel visual instead of in the same tank. This greatly facilitates the application because the tube walls are thin and fixing the detector can be accomplished with simple plastic or [...]

Rotatory blades

Available for vertical installation on the roof or lateral walls allows the detection in solids and liquids. The sensor detects the increase in torque upon contact with the product to be detected, switching TO an electrical contact. Different versions are available with one, two or four blades, different shaft lengths, high temperature versions, versions Atex, etc.

Capacitive

Capacitive detectors perform continuous measurement according to the alteration of the capacitance along a bulb (depending on the ratio of bulb in contact with the product). They are very common in the DLM-35 and CLM-36. Application in liquids and granulated solids. For its constructive shape and its application, we can distinguish several types: Typically the amplifying electronics is installed on the same probe head and incorporates supply, output and adjustment. Like models DLS35 and from our represented DINEL. Programming of 0 and scale is done easily by magnetic contacts. The analogic output can be 4 to 20mA or 0 to [...]

Vibratory

Applicable solids or liquids activate a contact when the product comes into contact with a vibrating fork. The alteration of the medium alters the vibration of the fork. Constructed in different metals, it is easily installable and maintenance free. It can be installed horizontally or in vertical position with different lengths.

Membrane

Usually applied to granulates. Based on the behavior of a frontal membrane that when deformed by the presence of the product, it triggers an internal microswitch. The installation is always done in vertical position, fixed to the wall by flange.
