thyrcont图拉特真空计VSH88D
The digital combination transducer VSH (Pirani/hot cathode) 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
Easily replaceable sensor heads with stored calibration data
应用
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
