Temperature limitors WT-12… WT-30
The purpose of temperature limiters WT-12..., WT-30... is temperature control of elements of structures in selected places, e.g. on machine housings, conveyor structures or on elements of compressor units. The temperature limiters may be installed in rooms of grade "a", "b"and "c" of methane explosion hazard and of class "A" or "B" of coal dust explosion hazard. They may be applied for co-operation with spark-safe circuits.
They are manufactured in varieties:
- WT-12N, WT-30N - contact,
- WT-12D, WT-30D - with a diode incorporated in series.
Differences of structures:
- limiters WT-12... have a M12x1,25 thread
- limiters WT-30... have a M30x1,5 thread
