The 355410-1-YE-T Micro-Ion® Hot Cathode Vacuum Transducer features a yttria-coated iridium filament, a size NW25 ISO-KF fitting and RS485 communications. One set point relay is included. Micro-Ion® vacuum transducers combine 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.
