SIRAX BM200 Analog Meters with Moving-Coil Movement and 90° Scale

Date:2023-08-04      Category:Articles

The analog display measuring devices with moving coil measuring mecha nism SIRAX BM200 in a polycarbonate housing and 90° scale are intended for measuring DC currents or DC voltages.
The moving-coil measuring mechanism consists of a core magnet system with point bearings spring-loaded on both sides.
The measuring devices are designed for installation in control panels, machine consoles or mosaic grids up to a panel thickness of no more than 25mm.
The bezel, the glass window and the dial can be easily exchanged on site.

Features

●Robust polycarbonate housing with high flammability class UL94-V0
●Simple assembly using swivel screw
●Quick and easy connection using screws and clamps
●Full-surface rear wall cover as protection against accidental contact
●90° scale
●Linear scale
●Easy replacement of the glass window, the front bezel and the scale
