  • All-welded diaphragm vacuum pressure sensor
  • 4-20 mA, 0-10 VDC and setpoint switch output
  • Programmable settings, range and configuration via S4-Connect™
  • Compact and robust 316 stainless steel design

ADVANTAGES SERIES

  • All-welded corrosion resistant stainless steel diaphragm
  • Temperature drift compensated
  • Configurable with plug and play USB communicator
  • Robust ultra compact 316 stainless steel design
  • IP67 enclosure for harsh environments
  • Optional solid-state setpoint relay for process control

The VSM-1 series vacuum transmitter is designed for measurement in a variety of industrial applications.  Its modular compact design offers a unique combination of high measurement performance, flexible configuration and a robust stainless steel design. Applications include vacuum fore-line surveillance, freeze-drying and heat treatment furnaces. The VSM-1 is programmable and configurable from a PC via the novel S4-Connect interface.

 

Diaphragm sensor technology

he VSM-1 transducer is based on a 316 stainless steel sensor diaphragm that converts the applied pressure to an electric signal. The ceramic sensor surface in combination with the 316 stainless steel flange and internal Viton® sealing offers excellent chemical resistance and compatibility with a wide range of aggressive gases, solvents and acids. The VSM-1 sensor is built to last and can withstand continuous vibrations and instant pressure changes from vacuum to atmosphere.
