Series-TDFS2

Flow Switch, LED Indicators, Adjustable Flow Rate, NO/NC Outputs

Interrupteur de débit, indicateurs LED, débit réglable, sorties NO/NC

Better reliability and life expectancy than mechanical flow switches with no paddles or vanes to wear or break, no jams in the paddle movement, and no seals on movement assembly to wear or leak
Long operation life, as it is not affected by empty pipe by avoiding overheating with heating above the process temperature and then cooling down to process temperature
Lower system run cost due to low pressure drop with 10% insertion into the flow (e.g. 1/8" for 3/4" schedule 40 pipe)

Le commutateur de débit à dispersion thermique série TDFS2 est une vanne d'arrêt du débit thermique qui indique si le débit est supérieur ou inférieur à un débit défini par l'utilisateur. L'appareil comprend deux voyants d'état à DEL qui fournissent une indication visuelle du commutateur. Le débit de consigne (valeur de consigne) est facilement réglable sur site à l'aide de l'aimant fourni et l'appareil dispose à la fois de sorties NO et NC NPN.
