1 Brief description
The device is tested according to ATEX directive 94/9/EG as associated equipment with intrinsically safe output.
It meets the requirements of the following identification markings:
1-sensor variant
2-sensor variant
The device is also certified for use according to DIN EN 50495 and DIN EN 13463-6 as an ignition source monitor as specified
in the ATEX directive.
The compact and freely configurable STB/STW can now also enable early and reliable detection of risks in Ex-areas which
could potentially result in personal injuries, environmental damage, or destruction of the production plants and production ma-
terials.
The primary task of safety temperature limiters is to reliably monitor thermal processes and to switch plants to a safe operating
status in the event of malfunctions.
Along with the existing approvals according to DIN 14597, SIL3, PL e (Performance Level), GL, the device also has approval
according to ATEX and can therefore also be used in Ex-areas.
The inputs are intrinsically safe [Ex ia] so that relevant probes can be connected directly.
Barriers are no longer required. The device is also certified according to DIN EN 50495 and DIN EN 13463-6 as a monitoring
device for potential ignition sources (iPL 2) as specified in the ATEX directive and can be used to monitor potentially explosive
atmospheres containing gas or dust.
