Bentrup
controllers can sense important faults that may occur with
the kiln during firing, such as broken thermocouples, broken
elements or a faulty door switch. The most vital feature
is that the controller is able to sense if the temperature
fails to rise, shutting the kiln down before any expensive
damage is incurred. Also, if the actual kiln temperature
exceeds the set point temperature by 20°C a shut down
will occur.
All
kilns are fitted with an additional "safety" contactor,
ensuring that if one contactor fails the safety contactor
will still be able to switch the kiln off. Front loading
kilns are also fitted with a traditional heat fuse, which
will turn off the kiln if all other back-up systems fail.
These
kilns can therefore be fired without constant monitoring
after starting. This ensures peace of mind for the potter
once the firing has commenced.
These
safety features are particularly important in schools where
the safety of the kiln is of the utmost importance.
