Thermostate – Präzisionsgeräte
Bimetall-Thermostate mit Schnappverschluss und SPST-Ausgang. Geräte mit und ohne hermetischer Verriegelung erhältlich. Versionen mit optimierter Zuverlässigkeit entsprechen den hohen Anforderungen an die im Militärwesen und in der Luft- und Raumfahrt üblichen Anforderungen an die dielektrische Stärke, die Feuchtigkeit, den Widerstand sowie die Schwingungs- und Stoßfestigkeit. Verfügbar in Flachausführung, mit Logik-Pegel und automatischer Rückstellung.
