Description

The NV6a amplifies, filters and normalizes 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.

Application

The NV6a has its application anywhere a SEIKA sensor is, without much expenditure and under optimal compatibility, to be connected to measuring equipment operating on 4...20mA, 2-wire current loop basis and subsequent adjustment of amplification and zero position are necessary.
Typical applications are the coupling with memory programmable control systems and the signal transmission over long distances with little transmission line setup.

Description

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.
