Modular vacuum gauges are an ideal solution for applications that do not need front panel displays and controls. These compact, convenient, reliable, cost-saving modules have the control electronics mounted directly on the gauge. The all-metal package provides a rugged enclosure and a high level of immunity to electrical noise.

Vacuum Gauge Modules
Vacuum pressure measurements over seven decades from atmosphere to 1×10-4 Torr (1×10-4 mbar, 1×10-2 Pa) are provided by Granville-Phillips Mini-Convectron Modules. Versions are available with analog output, RS-485 interface, or with DeviceNet™ interface (described in a separate brochure). The basic versions have adjustable setpoint relays that allow you to control other functions of your vacuum process or provide safety interlocking. The digital display version features a bright, 3-digit display that gives instantaneous on-site pressure measurement. A version with a convenient linear analog output signal is also available.

Convectron Gauge Technology
With over 20 years of successful field installations, the Granville-Phillips 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,
Convectron Gauges take advantage of heat loss due to convection cooling at higher pressures. This extends the range of accurate, repeatable vacuum measurements
to atmosphere. To assure the highest level of accuracy and gauge-to-gauge repeatability, each Convectron Gauge is individually calibrated at our factory.

Convectron Gauges are in use today on hundreds of thousands of vacuum processes throughout the world, making them a wise choice for many vacuum applications.
