Measuring Data via Radio and Inductively
MANNER Sensortelemetrie has further developed the successful sensor telemetry system. A particular variant now allows measured data to optionally be transmitted both inductively and by radio. Thus, the respective advantages of the different types of systems are combined. As is known, the battery-powered radio telemetry system is the most simple to use, since the installation of pickup and rotor induction loop is eliminated. Particularly characteristic is that the system exhibits a range of up to 50 metres in battery operation. This is ideal for so-called short-term ‘quick and dirty’ measurement tasks. On the other hand, the inductive sensor telemetry system is distinguished by unlimited service life and extreme robustness under severe environmental conditions. Depending on the application, one or the other type of system is beneficial.
The new system is available for both short-term measurement tasks using a battery and for long-term measurements with inductive power supply for unlimited runtime. Consequentially, metering service providers would only need to carry one type of system, simplifying logistics and maintenance significantly. This way, a system installed for short-term measurements could, if beneficial, easily be converted for long-term measurements.
As with the existing systems, the measured values are digitised with 16 bit and transmitted in secure code. This guarantees not only high accuracy, but also high reliability despite a radio transmission. The usual remote control capability of the sensitive adjustable measurement range and auto zero do not have to be abandoned either.
The measurement data are transmitted analogue or via the CAN bus or USB interfaces.
