Overview
Overview
The 392502-2-YE-T Granville-Phillips® 392 Micro-Ion® Plus Vacuum Gauge Module features a NW25 ISO-KF fitting and RS485 communications. A digital display for local pressure readings is included. Two set point control relays are included to simplify process control functions. Settings are configurable through the RS-485 interface. It is a second generation full range pressure measurement module that combines industry-standard Micro-Ion® ionization vacuum gauge technology with a miniature Pirani Conductron heat-loss sensor to provide accurate, continuous pressure measurement from high vacuum to atmosphere. The 392 Micro-Ion® Plus Vacuum Gauge Module combines Granville-Phillips® industry-standard and application-tested Micro-Ion® ionization vacuum sensor with an innovative miniature Pirani Conductron vacuum sensor in a single gauge assembly with a compact electronics control module. The 392 Micro-Ion® Plus Vacuum Gauge Module compact modular design reduces the number of separate gauges, vacuum interfaces, cabling and control electronics that are typically required for full range pressure measurement. The full range pressure measurement is output as a single analog signal.
