Series 275 Convectron Module with DeviceNet
Instruction Manual - 275502 13
2.1 The Mini-Convectron Gauge Module
Introduction/Specifications
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.
The Mini-Convectron module is a self-contained measurement device incorporating Convectron
gauge technology and electronics in a compact modular design. The electronics and gauge are
packaged in an all-metal package that provides a rugged enclosure and a high level of immunity to
electrical noise. The Convectron gauge used in the module is field-replaceable.
The Mini-Convectron module is available in a variety of output configurations. This instruction manual
is for use with a Mini-Convectron Module with DeviceNet interface and one
pressure-threshold setpoint relay. The adjustable setpoint allows control of valves, switches, alarm
signals, or other controls.
Within this manual:
•
The term “Module” refers to the entire Mini-Convectron Module.
•
The term “Gauge” refers to the replaceable Convectron Gauge inside the module.
