(15) Equipment description and technical data

Reed level sensors, models BLR-SAI, BLR-SBI and FLR-SAI, FLR-SBI (NMG125***, MG***,

hereinafter – the level sensors) and float switches FLS-SBI and HLS-SI (60-***, HAG***, hereinafter – the

switches) are used to monitor the level of liquid media in containers and vessels.

The level sensors work on the principle of a float with permanent magnet moving with the level of liquid

medium along a guide tube in which a measuring chain is installed.

The resistance measuring chain is made up of chips soldered onto a printed circuit board, the chips

containing reed contacts and resistors. The magnetic field of the float actuates the reed contacts, and the chain

operates in a 3-wire potentiometer circuit, where the voltage drop is proportional to the fill level of the liquid

medium. Some versions do not contain resistors, and level indication is achieved by direct switching of the reed

contacts.

The switches have a similar design, except that the tube contains one or more reed contacts for

determination of the limit level only (or some limit levels).

In addition, the level sensors and switches may include temperature sensors PT100 or РТ1000, and level

transducers.

The level sensors and switches consist of a housing and a tube made of stainless steel immersed directly

into the measured liquid medium.
