Smart Limiter

intelligent temperature limiter

The electronic temperature limiter "Smart Limiter" is used in potentially explosive areas when using an electrical heat tracing system with DIN rail mounting. It is characterised by its "smart" switching behaviour, i.e. it only switches off at the set maximum temperature if an excess temperature is measured and the system's temperature controller has not switched off.

In practice, this means, for example, that the system can be steam flushed without having to reset the limiter afterwards.
