Description

The NV4a amplifies, filters and normalizes the output signals of SEIKA sensors. The symmetrical output signal enables unproblematic subsequent signal processing with standard measuring instruments such as oscilloscopes, transient recorders, A/D converters, multimeters, etc. 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.

Application

The NV4a has its application anywhere a SEIKA sensor is, without much expenditure and under optimal compatibility, to be connected to application specific measuring equipment with optimal matching conditions, and where subsequent adjustments to amplification and zero voltage are necessary.

Connections

Attention! Do not short circuit the supply voltage (9 to 30 V) with the output. The negative operating voltage for the symmetrical output voltage is internally generated in the NV4a from the purely positive supply voltage.
