Description
Seika NV6a Filtering signal conditioner for sensor signal matching to a 4…20mA, 2-wire interface.
The NV6a filtering signal conditioner amplifies, filters and normalises the output signals of SEIKA sensors. The symmetrical output signal enables unproblematic subsequent signal processing on the basis of 4…20mA current loop technology.
The NV6a does not require a separate supply voltage, as the internal operating voltage feeds off the current loop. The NV6a furthermore provides a highly stable 5V sensor supply voltage with short circuit current limitation.
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.
