thyrcont圖拉特真空計(jì)VSM77DL

VSM77DL Vacuum Transducer ● DN25KF ● LCD display

The digital combination vacuum transducer VSM (Pirani/cold 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 / 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
Large, integrated LCD display with background illumination
Two independent, potential-free relay switch points
Easily replaceable sensor heads with stored calibration data
