The control unit of the resistance type BCS-2

The description and use of the control unit the resistance of BKS-2:

The control unit of the resistance type BCS-2 is designed to control one (BKS-2.1) or two (BCS-2.2) levels of conductive liquid and dry environments (water, ore, rock, coal, etc.) with one or two electrode sensor level.

Unit BKS-2 is installed out of explosion hazard premises and external installations.

Level sensor BCS-2 meets the requirements of GOST 22782.5-78 and bears the marking "OExiaIICT6" complete with BKS-2I. The sensor is designed for installations in explosive zones of premises and external installations according to sec. 3 pack "regulations for electrical installation (RB-76 )" and other legislative documents regulating the installation of electrical equipment in hazardous areas.

Control unit BKS-2 can also operate on other commercially available contact sensors that meet the requirements above.

The block resistance of BKS-2 produced in UHL location category 3 according to GOST 15150-69, the conditions of operation of the following:

• height above sea level up to 2000 m;
• ambient temperature from minus 40 to plus 40 °C;
• the vibration of fixing up to a frequency of 35 Hz and an acceleration of 0.5 g;
• relative humidity up to 98% at 25 °C without moisture condensation;
• the environment does not contain aggressive gases and vapors in
• the concentration destroying metals and insulation;
• working position and the vertical space.
