Filtering signal conditioner for sensor signal matching with an asymmetric 0...5V output voltage
The NV8a amplifies,
filters and normalizes the output signals of SEIKA sensors. The
asymmetric output signal enables unproblematic, subsequent signal
processing with standard measuring equipment, such as
oscilloscopes, transient recorders, A/D converters, multimeters,
etc., operating with this asymmetric signal level.
The NV8a requires a non-stabilized supply voltage in the range of 9...30 Volt. The NV8a provides a highly stable 5V voltage with short circuit current limitation as a sensor supply voltage.
Multiple internal switching variants allow for optimal adaptation of signal processing parameters, such as settling time, filter cut-off frequencies and amplification and zero point adjustment, to the measuring task.
The NV8a has its application anywhere a SEIKA sensor is, without great expenditures and under optimal compatibility, to be connected to application specific measuring equipment and subsequent adjustment of amplification and zero position are necessary. The use of an asymmetric output voltage requires minimal electronics for further signal processing.
