The MKS Micro-Ion® Transducer combines the world's smallest ionization gauge with the control electronics to create a compact, convenient, reliable, and cost-saving solution for many high vacuum applications. This Micro-Ion® vacuum gauge includes many features that provide for a much more accurate and repeatable measurement than traditional Bayard-Alpert gauges from 5 x 10-2 Torr to 10-9 Torr. The all-metal package provides a rugged enclosure and a high level of immunity to electrical noise. High performance in a small volume is achieved though a number of enhancements including a patented dual ion collector design that optimizes electron motion and ion collection.

The 355 transducer is available with analog output, RS485 or DeviceNet interfaces. The analog output and DeviceNet versions have a digital display option for convenient, point-of-use pressure readout.

Features & Benefits:

  • Compact, convenient, reliable, cost-saving vacuum measurement
  • Vacuum pressure measurement to 10-9 Torr (10-9 mbar, 10-7 Pa)
  • Dual filaments increase equipment uptime
  • Ultra-clean construction allows rapid response during pump down
  • Rugged, all-metal, RF and noise-immune module is CE compliant
  • Optional local display aids in setup and diagnostics
  • RS485 and DeviceNet digital interfaces available
