A special variant now allows the optional transmission of measurement data both inductively and by radio. This combines the respective advantages of the different system types. As is well known, the battery-powered radio telemetry system is characterized by very simple handling, as there is no need to install a pickup and rotor induction loop. A special feature is that the system has a range of up to 50 m in battery operation. This is ideal for short-term so-called “quick and dirty” measurement tasks. Nevertheless, multi-channel signal bandwidths of up to 40 kHz can be realized. In contrast, the inductive sensor telemetry system is characterized by unlimited operating time and extreme robustness under difficult environmental conditions. Interferences are irrelevant. Depending on the application, one or the other system type is advantageous.
The new system can be used both for short-term measuring tasks using a battery and for long-term measurements with inductive supply with unlimited operating time. Measurement service providers therefore only need to carry one system type with extremely low weight in their hand luggage, making logistics and maintenance considerably easier. This means that even a system mounted for short-term measurement can be converted to long-term measurement in the simplest possible way if required.
As with the existing systems, the measured values are digitized with 16 bits and transmitted in a code-secured way. This guarantees, in addition to high accuracy, a high reliability despite radio transmission. The incoming measurement signals are of extraordinary quality. Signal interference is a thing of the past. Even the usual remote control with the sensitively adjustable measuring ranges and autozero are still available. In any case, the measurement data is transmitted digitally without loss of accuracy and made available for further processing in analog form or via the CAN bus, USB, EtherNet or EtherCat interfaces. This means that a measurement service provider is optimally equipped for all tasks with one hardware.
