Abstract: A temperature controller including a housing, a temperature sensor with an expansion element which generates a movement stroke as a function of the temperature. The controller includes a switching system having a switching spring on a switching spring base, upon which there acts the expansion element. An end remote from the spring contact of the switching spring is fastened to the switching spring base, an end remote from the fastening of the switching spring of the switching spring base is held securely and immovably on the temperature controller housing, the switching spring base working together with an adjustment element. To adjust the switching point of the switching system, the switching spring base together with the switching spring can be moved relative to the expansion element and/or to the actuating element.

Abstract: The invention relates to a temperature switch comprising a housing (2), a switching system (3) consisting of a first support (3.1) with a fixed contact (3.2) and a second support (3.3), on which a switch spring (3.4) with a switch contact (3.5) is arranged and a switching arrangement (4), which effects a positional change of the switch contact (3.5) as a function of the temperature.

Abstract: A temperature controller including a housing (5), a temperature sensor (2) with an expansion element (6) which generates a movement stroke as a function of the temperature. The controller includes a switching system (4) having a switching spring (19) on a switching spring base (16), upon which there act the expansion element (6). An end (16.2) remote from the spring contact (21) of the switching spring (19) is fastened to the switching spring base (16), an end (16.1) remote from the fastening of the switching spring (19) of the switching spring base (16) is held securely and immovably on the temperature controller housing (5), the switching spring base (16) working together with an adjustment element (24). To adjust the switching point of the switching system (4), the switching spring base (16) together with the switching spring (19) can be moved relative to the expansion element (6) and/or to the actuating element (8).

Abstract: A gas sensor is described comprising a solid electrolytic cell having at least one solid electrolyte and at least two electrodes, disposed on opposite surfaces of the solid electrolyte, namely a reference electrode and a measurement electrode. The reference electrode is disposed in a reference chamber. At least part of a wall of the reference chamber is formed by a heating element comprising a ceramic substrate. The measurement electrode is disposed in a measurement chamber containing the sample gas. At least part of a wall of the measurement chamber comprises a fine filter for separation of pollutant gases from the sample gas and the measurement chamber is otherwise sealed off in a gastight manner. The fine filter, the solid electrolyte and the ceramic substrate of the heating element are disposed one above the other in the form of a sandwich structure and connected to one another by connecting elements.
