Funktionen und Vorteile

  • Kann in den CR9000X ein- und wieder ausgebaut werden um wechselnden Messaufgaben gerecht zu werden
  • Mit dem CR9055EC lassen sich Sensoren einfach vom CR9000X trennen, so dass der Datenlogger von einer Messstelle zur nächsten bewegt werden kann
  • Misst Spannungen bis zu ±50 V


Technische Beschreibung

The CR9055E is an I/O module for the CR9000X-series and CR9000-series dataloggers. It contains 14 differential (28 single-ended) input channels for measuring voltages up to ±50 V. The resolution on the most sensitive range is 16 microvolts.

The CR9055E includes one CR9055EC easy connector module. Easy connector modules allow sensor wiring to remain connected while the input module’s measurement electronics and the rest of the datalogger system are used elsewhere. Additional CR9055ECs are purchased as a separate line item.
