(15) Equipment description and technical data

Magnetic switches, model BGU****, are intended for installation on bypass level indicators, models

BNA*******Ех and UTN*******Ех, they are used for switching of electric circuit at a specified level. For this

purposes, one or several magnetic switches may be mounted on a bypass level indicator.

The magnetic switches, model BGU*** consist of an aluminium or stainless steel case with a reed switch

or a proximity switch mounted in it (depending on version). An external magnet (mounted inside float of bypass

level indicator) closes or opens the reed switch or the proximity switch.

Designations of the switches depending on version, and their technical specifications are described

below:

Switches BGU***I, BGU***RI and BGU***NI with marking II 1 G Ex ia IIC T3…T6 Ga are intended

for connection to certified intrinsically safe circuits with marking Ex [ia IIC Ga], they have intrinsic safety

specifications as follows:

Switches with a reed contact:

Ui = 30 V, Ii = 100 mA, Рі = 1 W, Ci and Li = 0

Intrinsic safety specifications of switches with a proximity switch:

Ui = 16 V, Ci = 30 nF, Li = 100 µH

Other specifications – see the Table for temperature ratings.
