n-Spektor mobile unit

The n-Spektor™ Acquisition Processor offers non-intrusive control independent data acquisition. Signals are measured at the process level for increased reliability.

SPN engineers use their in depth knowledge of the process and machinery to ensure that key data is measured at strategic connection points.

Special attention is given to attaching signal isolators to drives and machines in a manner that enables safe, reliable and continuous high speed acquisition.

The n-Spektor™ Acquisition processor provides access to digital, analog and frequency signals from machine sensors, drives, controls and process transducers.

SPN uses high impedance signal isolators located close to the signal measuring point in order to prevent any interference with the controls.

  • Fixed, mobile or portable type units
  • Analog, Digital & Frequency hardwired inputs
  • High impedance signal isolators, input signal range from ± 100mV to ± 1000V with 1500Vrms signal isolation
  • Anti-Aliasing filtering on analog channels
  • Continuous sampling at 2500 s/s/channel
  • On board processor for high speed sampling
