One and two input Counters simplify applications in hazardous and safe areas
BEKA associates new one and two input pulse Counters can economically perform industrial counting functions in hazardous and safe areas. All models have large easy to read displays with optional backlighting, isolated synchronous pulse and 4/20mA outputs, plus dual alarms.
The two input Counters can display the sum or difference of the inputs in engineering units and when configured for use with a quadrature encoder, the position and speed of a shaft or cable can be shown.
Intrinsically safe models with ATEX, IECEx, US and Canadian certification may be installed in gas and dust hazardous areas. For applications in Zone 2 or 22, Ex nA and Ex tc approval of the stainless steel model permits installation without the need for Zener barriers or galvanic isolators, significantly reducing cost.
Although well documented and easy to configure on-site, Counters can be supplied configured with requested scale card marking for no additional charge.
