Abstract: A temperature control device for arrangement on a surface to be tempered, having an upper part, a lower part, an electrical connection and at least one first tempering element in connection with the electrical connection. The lower part is designed for engagement with the upper part such that a surface pressure can be provided with the upper part and the lower part in the orthogonal direction to an upper side and a lower side of the first tempering element for surface coupling of the lower part to the surface to be tempered. The temperature control device can be fastened longitudinally displaceably to the surface to be tempered in such a way that a change in length of the temperature control device in the longitudinal direction of the temperature control device can be accommodated.

Abstract: A sensor hub may be used to address complex cabling issues. Such sensor hub may include at least one sensor communication device designed to receive sensor signals from at least two sensors and/or to output signals to the at least two sensors; a computer device communicatively connected to the at least one sensor communication device and designed to generate sensor data using the sensor signals; and a transmitting device designed to transmit the sensor data to a user device via a single communications medium. The sensor data indicate addresses which are each assigned to one of the at least two sensors.

Abstract: The invention relates to a device for temperature control in potentially explosive areas, comprising a temperature controller (10) and a housing (11) in which the temperature controller (10) is arranged, the housing (11) having a sealed opening (12) through which electrical lines (13, 14) of the temperature controller (10) are passed. It is characterized in that the temperature controller (10) has a measuring surface (15) which lies directly against an inner wall (16) of the housing (11) at least in certain areas and is electrically connected to an earthing tab (17), said earthing tab (17) being electrically connected to another line (18) which is guided through the opening (12).

Abstract: A luminaire comprising a circuit board having at least one LED illuminant arranged on the circuit board, wherein the circuit board is arranged in a luminaire housing with a translucent housing section. The circuit board includes a switching device for switching the at least one LED illuminant on and off with at least one reed switch, wherein the reed switch is arranged on the circuit board between at least one power connection and the at least one LED illuminant and is magnetically switchable for disconnecting or connecting a central power supply for the at least one LED illuminant.

Abstract: The invention relates to a fan device with at least one locking element for securing the fan device to a wall portion, in particular to an electrical enclosure wall, with a front and a rear face. The fan device is inserted into a front-face wall portion opening in a pressureless manner, and the locking element is movable in the direction of the rear face of the wall portion in the inserted state.

Abstract: A temperature control device, in particular a resistance heating device, for arrangement on a surface to be tempered, having at least one upper part, a lower part, an electrical connection and at least one first tempering element, in particular a heating element, in connection with the electrical connection. The upper part is arranged opposite an upper side of the first tempering element and the lower part is arranged opposite an underside of the first tempering element. The lower part is designed for engagement with the upper part such that a surface pressure can be provided with the upper part and the lower part in the orthogonal direction to the upper side and the lower side of the first tempering element for surface coupling of the lower part to the surface to be tempered.
