Based on the model 781 gas filled temperature switch this bespoke solution incorporates a special sensing probe that responds very quickly to ambient temperature changes.
These models are used extensively in the nuclear power industry for rapidly detecting ambient temperature rises inside the plant that may indicate a steam pipe leak. With correct installation and good air circulation, these switches can react to a change in ambient temperature in <1 second.
