Overview
Overview
The 275620-2-GE-T Mini-Convectron® Modular Vacuum Gauge features a Gold Plated Tungsten sensor, a size NW25 ISO-KF fitting, and a DeviceNet interface. Two set point relays are included for safety interlocking, and a local display aids with set-up and diagnostics. Mini-Convectron® gauges combines the high precision convection enhanced Pirani gauge with electronics to provide a compact, convenient, reliable, and cost-saving solution for vacuum measurement from atmosphere to 10-4 Torr. With over 35 years of successful field installations, the Convectron® gauge has become an industry standard. It is a unique variation of thermal conductivity gauges where pressure measurement is based on the rate of heat loss from a sensor wire. Unlike traditional thermocouple and Pirani gauges that use only conductive heat loss, Convectron gauges take advantage of heat loss due to convection at higher pressures. This extends the range of accurate, repeatable measurement to atmosphere. These Granville-Phillips® vacuum gauges are ideal for applications where controller size and local control are critically important.
