      VSM78D Vacuum Transducer ● DN40KF

      The digital combination transducer VSM (Pirani/cold cathode) measures absolute pressure from atmospheric pressure to ultrahigh vacuum.
      The microcontroller intelligence of this vacuum gauge automatically manages the optional interplay of both vacuum sensors.

      描述

      • Wide range sensor Pirani / cold cathode

      • Pirani with extended range allows operation of cold cathode at lower pressure and increases lifetime

      • Robust sensor design, insensitive against inrush of air

      • Digital RS485 interface and analog output signal 1.819-8.6 V

      • Automatic baud rate detection 9.6 kBd to 115 kBd

      • Two independent, potential-free relay switch points

      • Easily replaceable sensor heads with stored calibration data

      應(yīng)用

      • Mass spectrometry

      • Coating plants and vapor deposition

      • Measuring and controlling in fine and ultrahigh vacuum

      • Process engineering

      • Sputtering plants

      • Vacuum furnaces
