Pirani vacuum transmitter VSH

hot cathodedigitalRS485

Absolute pressure 1000 mbar to 5e-10 mbar (=hPa), 750 Torr to 5e-10 Torr The compact combination gauge VSH (Pirani/hot cathode) measures absolute pressure from atmosphere to ultra-high vacuum. The intelligence of internal microprocessors ensures a seamless transition between the two sensor principles and therefore high accuracy. Your advantages » Large measuring range thanks to Pirani/Bayard Alpert combination sensor » Pirani with wide measuring range, allowing operation of the hot cathode at low pressure, ensuring optimized service life » Excellent accuracy and reproducibility » Bayard-Alpert with blowing resistant, yttrium coated double filament » Digital RS485 interface plus 0-10 V output signal, EtherCAT or PROFINET » Bluetooth adapter SLKBT enables wireless communication » Automatic baud rate detection 9.6 kBd to 115 kBd » Optionally with large, integrated LCD display with backlighting (VSH88DL, VSH89DL) » Two independent, potential-free relay switch points » Easily replaceable calibrated sensor heads Examples of applications » Analysis technology » Evaporation and coating systems » Measurement and control in the fine and high vacuum range » Process engineering » Vacuum furnaces » Sputtering systems
