Signal acquisition system K20-16E

Image K20-16E

Metrolog K20-16E is a compact signal acquisition system ideal for multi-point test, online monitoring of complex industrial processes and high density data acquisition.

With 16 input channels for unipolar (0-10VDC) or bipolar (±10VDC) DC voltage signals and USB, RS232 and I/O interfaces, the K20-16E allows quick and easy data acquisition.


  • 16 input channels (mini-DIN4 connectors)
  • Compatible with LVDT linear displacement sensors with single or symmetrical DC output, plug gauges, potentiometric sensors, pressure transducers with amplified voltage or current output, load-cells, temperature sensors, compatible voltage signal from external electronic circuits.
  • Signal acquisition system with thermal and electronic drift compensation. ΔΣ 24-bit A/D converter with high precision voltage reference and digital input filter (10Hz cutoff frequency).
  • Measuring range: -10VDC to + 10VDC with over/under voltage protection.
