A heating control system, monitoring system and predictive maintenance radio sensor system. The heating control system comprises at least one temperature transducer element having a downstream voltage transformer; an energy storage device which is electrically coupled to the at least one voltage transformer; a logic assembly coupled to the energy storage device and having sequence control; a data transmission unit coupled to the logic assembly; and a sensor, coupled to the logic assembly, for measuring ambient parameters.

Heating control system

An energy-autonomous sensor for detection of physical environmental parameters, having at least one sensor element, one storage element and one control circuit, with a timer circuit which is activated on reaching a predetermined electrical voltage on the storage element, activates the sensor and the control circuit at predetermined time intervals, and deactivates them after a predetermined operating time, such that this results in a time duration of sensor operation and a sensor operation pause.

Sensor

A sensor system has a least one voltage generator for conversion of non-electrical energy to electrical energy. At least one energy store is connected downstream from the voltage generator. At least one voltage converter is connected to the energy store such that its output signal is suitable for operation of a processor controller. At least one sensor is provided, and at least one transmitter enables wire-free transmission of transmission messages produced by the processor controller and containing at least one measured value from the at least one sensor. A timer circuit is triggered as a function of a voltage level of the at least one energy store, and activates the sensor system to transmit at least one transmission message after a specific time interval.

An encapsulated installation, in particular a switching installation for high or medium voltage, includes a plurality of sensors located in an interior of an encapsulation. A central monitoring device is provided for information interchange with the surface acoustic wave sensors. An antenna element of the monitoring device is disposed at the encapsulation and is directed towards the interior. The sensors can be interrogated selectively.

Encapsulated installation

In a passive surface wave sensor for measured value determination, a measured value is transmitted by radio from a remote measuring location to an interrogation device, which transmits energy by radio to a sensor element as an interrogation pulse. The surface wave sensor is suitable for contactless measured value acquisition. A surface wave configuration is the sensor element and a surface wave reference element is provided for phase discrimination and/or propagation time measurement. As a further development, a sensor operated with chirped transmitting signals and having chirped reflectors is provided, in which the configuration has a reference function in place of the reference element. A sensor constructed in such a way that it has a chirped function has the characteristics of an imminently temperature-compensated sensor for measuring other physical or similar variables.

An encapsulated tubular conductor having at least two antenna elements disposed on the capsule thereof for maintaining therebetween wireless information transmission in a transmitting-receiving direction, and a transmitting-receiving device located outside the capsule and assigned to one of the antenna elements includes another transmitting/receiving device also disposed outside the capsule and assigned to the other of the antenna elements, the antenna elements being directed towards an interior space of the capsule, the interior space serving as a transfer path via which information is transferable between the transmitting-receiving devices.

Encapsulated tubular conductor

A method for detecting the position of a switching device and an encapsulated switching installation having at least one switching device. A transmitted signal is emitted into the interior of an encapsulation to make it possible to easily detect the position of a switching device in an encapsulated switching installation. A resultant reflection signal is received and stored. After a repetition of this process, the two received reflection signals are compared with one another. In the event of any discrepancy, a message signal is produced for the new switching state.

A metalclad switchgear assembly for high or medium voltage, having a cladding, includes at least one sensor arranged in an interior space of the cladding for detecting a condition variable within the cladding, the sensor having an antenna; and a transmitting and receiving antenna directed towards the interior space, the transmitting and receiving antenna serving for performing a wireless information interchange with the sensor, and for simultaneously detecting electromagnetically partial discharges in the interior space.

A radio-interrogated, surface-wave technology current transformer for high/medium-voltage systems includes a magnetosensitive element connected to a surface-wave structure of a surface-wave configuration as a termination of the surface-wave structure. A response signal of the surface-wave configuration is information regarding current strength/direction and phase of the current instantaneously flowing through the system, which is evaluated by a ground station. By virtue of the radio transmission, there is no electrical insulation problem, and the use of a radio-interrogated surface-wave configuration makes that part of the overall current transducer which is at high potential into a passive element of the same.
