      VSH88DL Vacuum Transducer ● DN40KF ● LCD display

      The digital combination vacuum transducer VSH (Pirani/hot cathode) with integrated display measures absolute pressure from atmospheric pressure to ultrahigh vacuum.
      Microcontroller intelligence automatically manages the optional interplay of both vacuum sensors. Smartline vacuum gauges represent cutting edge technology providing safe, precise and cost effective process control.

      描述

      • Wide range sensor Pirani / Bayard Alpert

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

      • Excellent accuracy and repeatability

      • Bayard-Alpert with blowing resistant, yttrium coated double filament,
        insensitive against inrush of air

      • Digital RS485 interface and analog output signal 1.219-8.6 V

      • Automatic baud rate detection 9.6 kBd to 115 kBd

      • Two independent, potential-free relay switch points

      • With large, integrated LCD display with background illumination

      • Easily replaceable sensor heads with stored calibration data

      應(yīng)用

      • Coating plants and vapor deposition

      • Sputtering plants

      • Analysis technology

      • Measuring and controlling in the fine and ultrahigh vacuum range

      • Vacuum furnaces

      • Process engineering

      • Space simulation chambers
