The DEEneo signal conditioner was developed for operating inductive LVDT sensors (full bridge). The electronics supply the sensor and convert the sensor signal into a standardized, analogue output signal with the help of a microcontroller.
DEEneo supports the operation of all LVDT sensors. The primary coil of the connected sensor is excited with a sinusoidal signal. To determine the sensor position, the secondary coil signals are calculated differentially and are used to generate an analog output singal. The internal, ratiometric signal processing is digital and guarantees high resolution and immunity to external influences (EMC).
The frequency and amplitude can be set using the eddySetup configuration software for optimum performance of the measuring chain. A push button (SET button) is used for the basic configuration and to set the measuring range limits - this enables quick and easy adaptation to the customer‘s application. Extended functions such as alarm and switching outputs can be configured as required via the USB interface.
Please note: Where possible, eddylab calibrates the sensor and electronics together. The sensor characteristic curve can be linearized to meet the highest demands on the accuracy of the measuring chain.
