Intended use

These devices are used to control, with a continous measurement with a 4-20 mA or resisitve Ω output, the level in tanks, containers, bypass pipes, ... of liquids like waters, oils, chemical products, ... with non-ferric particles in suspension are used.

The magnetic transducers are indicators that are made under request depending on each application. The material of the indicator body, float, length of the device, process connection (thread, flange, clamp flange), electrical output (cable output, DIN connector, connection box) and the required resolution.

Models in Stainless Steel 1.4401: models with Ø 12 mm body, with Ø 52x52 mm float and maximum lenght up to 2.500 mm. There are other float models depending on the application (Ø 44 mm, Ø 95 mm with roominess).

Also, there are models with PVC or Polypropylene housing with a Polypropylene Ø 38x60 mm float or PVDF housing with PVDF Ø38x60 mm float.

To use these devices in ambients with vapour, the contacts can be protected with condensation protection gel (removal contacts in the future) or with Epoxy resin (non-removable contacts in the future) that can extend the lifetime of the device.

Function

The magnetic transducers have a guide-way body where a float moves. Inside the body there are REED contacts associated with resistances that change a proportional output due to the magnetic field of the magnet placed inside the float depending on the position of the float. There are models with resisitve Ω output and models with a 4-20 mA output that allows the electrial connection of 2, 3 or 4 wires.

Mechanical connection

The standard form is mounting the device with the thread or flange proccess connection. Drill a hole in the top of the tank or container, polish it to prevent damage and place the group to the wall verifying the position of the device.

Depending on the application, the indicator can be mounted from the bottom of the tank or container (facing down).

For a correct use of the level switch, the float must not touch the walls of the tank and it is necessary to ensure the free movement of the float.
