Abstract

Ein Temperaturschalter, der insbesondere als Temperaturbe­ grenzer für einen Strahlungs-Heizkörper (11) zur Beheizung einer Glaskeramikplatte (12) dient, weist Strahlungsheizun­ gen (13, 14) auf. Sein stabförmiger Temperaturfühler (20) hat einen in einem als Vergleichsnormal dienenden Rohr (25) liegenden Ausdehnungsstab (24), der aus einer Chrom-Eisen-­ Aluminium-Legierung bestehen kann und oberhalb 1100 °C wär­ mebehandelt ist. Das Rohr (25) kann aus einem strahlungsab­ sorbierenden Material bestehen oder ist mit einem solchen beschichtet, beispielsweise Cordierit, nicht-transmissiver Glaskeramik oder Quarzgut. Beide Maßnahmen bewirken, daß der Temperaturschalter eine erhöhte Schaltamplitude und somit eine verringerte Schalthäufigkeit hat.
