Electronic level regulators: tech features, types and applications.

Electronic level switches are designed to control liquid levels by electronic probes and allow the delay time for starting up and shutting down an electric pump to be set according to usage requirements.

There are different types of electronic level switches and the difference lies in the nature and type of sensor that activates or switches off the operation of the hydraulic pump.

Electronic floor level regulators.

The CRAB electronic level switch rests on a flat surface, usually the floor or the bottom of a collection tank or a well, and thanks to the sensors placed on the base it detects the presence of liquids (1) and therefore activates the switching on of the hydraulic pump (2). The start-up of the electric pump, thanks to the magnetic key supplied, can be immediate or delayed as required. Once the liquid level has dropped (3) and the sensors on the base no longer detect it, the CRAB electronic level switch stops the hydraulic pump (4). Normally, both the switch-on and switch-off phases of the hydraulic pump occur with a delay of 5" the former, 30" the latter, in order to allow the liquid to be drained from the system. The CRAB electronic level regulator can be used with pumps capable of sucking water up to 2 mm. from the support surface.

It is also possible to directly connect the hydraulic pump to the electronic floor level regulator through the application of a SCHUKO PIGGYBACK PLUG (see image below) without the need for a dedicated electrical panel. This allows for a quick and easy installation of the electronic level switch without the need for experts to set up and certify the system.
This model of electronic level regulator is used in clear water as well as in turbid water, industrial and chemical water systems.

Electronic float level switches.

It may be the case that the electronic level regulator needs to control different liquid levels to meet customer requirements or because the level switch simply cannot be placed on the floor, at the base of the collection tank or well. In all these cases, the SNAKE electronic level switch can come to the rescue.

In these cases, the level switch controls the liquid level between the minimum and maximum level, i.e. the system switches the hydraulic pump on when the water reaches the defined maximum level and switches it off when the liquid reaches the set minimum level (see image below).

This model of switch or level regulator is also used in systems for handling clear, turbid, industrial or chemical water.

The SPIDER electronic level regulator model finds application in hydraulic systems for the management of clear, black and industrial water or with dissolved chemicals, but is particularly suitable for environments with turbulent water or in very confined or difficult-to-access spaces. In this case it is in fact possible, by means of flanged supports or  stainless steel or polyester fixing brackets, to insert only the rigid rods with the sensors into the working area. As with the other CRAB and SNAKE electronic level regulators, a hydraulic pump can be connected to the SPIDER electronic level switch by means of a SCHUKO PIGGYBACK PLUG.

As the CRAB and SNAKE models, the SPIDER level switch allows you to delay the start-up and shut-down of the water pump according to your requirements.
