Abstract
L'apparecchiatura comprende un isolatore-sonda (3) cavo internamente, un primo sistema (8/1) per fare circolare fluido freddo entro la cavità (4) dell'isolatore-sonda per raffreddare quest'ultimo a una temperatura tale che l'umidità esterna si condensi sulla superficie esterna, un secondo sistema (8/2) per misurare la conduttanza superficiale dell'isolatore-sonda, un terzo sistema per attivare un impianto di lavaggio di tutti gli isolatori installati nella stessa area quando detta conduttanza superficiale misurata abbia raggiunto un prestabilito valore critico; il dispositivo frigorifero per produrre detto fluido freddo comprende preferibilmente un gruppo di moduli Peltier (Fig. 1).
