High Temperature Bimetal Thermostats
Thermostats à Hautes Températures
Ce type de thermostat bimétallique peut opérer à des températures élevées jusqu’à 400°C. Normalement le seuil de 250°C est considéré comme la limite supérieure pour un thermostat à disque bimétallique, parce que le disque ne peut pas résister aux hautes températures. Nous employons un élément bimétallique plat en forme de lame pour la série H afin de réaliser la limite de la température de 400°C. L’utilisation de la lame bimétallique et d’un ressort en acier inoxydable occasionnant un mouvement de clic instantané sans étincelle, assurant la longue vie et une exactitude élevée.
SERIES K
Applications
Commande de procédés, soudure par vague, de l’équipement réfractaire de laboratoire, fours commerciaux, équipement de service de traiteur
