Explosion-proof Type

IGY3 Series.
Intrinsic safety structure
IGY3 Series.

It's the displacement sensor of intrinsic safety type based upon
international standards which can be used at zone 0.
(Class 0 hazardous area).
Class A grounding (first class grounding) isn't necessary adopting
a power transformer and photo coupler isolation system.
Possible to 100°C rod by option.

Probe & Magnet Controller P/A converter Construction
Zoom ZoomZoomZoom

・IGY3 series consist of a probe, a controller, a P/A converter, a magnet (or a float),
cable between probe and controller, and 1m cable between controller and P/A converter.
(Plastic magnet or float can't be used by law. )

・Probe has 1.5m cable with it. In case of extending cable,
It is possible to extend max. 400m by using the dedicated cable (2 core with shield).
(Please connect extend cable with 1.5m cable of probe in terminal box.)

・Probe and magnet (or float) should be installed in dangerous zone, and controller
and P/A converter should be installed in non dangerous zone.
