BA-30

Control of liquids
Magnetic floats switch

Intended use

Standard model for lateral mounting with Stainless Steel 1.4401 body, total length 45 mm and 30 mm of elbow, S.S. Ø 30x30 mm float, 1 NO contact reversible to NC, with thread process connection to mount the device from the inside of the tank and with cable output.

These devices are used to control the level in tanks, containers, bypass pipes, ... of liquids like waters, oils, chemical products, ... with non-ferric particles in suspension are used. This model is specially indicated to be control the maximum, minimum or an alarm level in small tanks.

Function

The magnetic float switch BA-30 has a guide-way body where a float moves. Inside the body there is a REED contact that change its position due to the magnetic field of the magnet placed inside the float when arrives at the contact point. When the liquid level falls, the float moves back and the signal turns into the initial position.

To reverse the NO contact to NC contact, take the float out and change the position 180º.

Mechanical connection

The standard form is mounting the device with the thread proccess connection. Drill a hole in the side of the tank or container, polish it to prevent damage and introduce the cable from inside and place the group to the wall verifying the position of the device. Keep the position of the group and tigthen the nut, verify the position of the indicator and connect the cable to the system of control.

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.
