The principle of operation of the level switch is based on measuring the density of the gamma radiation flux and activating the output signal while decreasing the density of the gamma radiation flux when it is blocked by a controlled environment. It is used for automatic control and process control in various industries.

The signaling device is a stationary device consisting of the following main components:

• The detection unit BDPS-03M • Measurement unit UAK-11.

The average service life of the device is at least 10 years. The criterion of the limiting state is the economic expediency of restoring the instrument's reliability by repair.

Features:

• Microprocessor control; • Detection unit based on a plastic scintillator; • Ability to integrate into process control systems; • Two-wire line connecting the detection unit; • Diagnostics of the detection unit and the communication cable with the detection unit; • Galvanic isolation of the detection unit and the output signal from the common wire of the measurement unit; • Archiving of all events: turning the device on and off, switching the count rate through the set thresholds, failure of the detection unit, cable break; • Protection of the detection unit from erroneous connection;
