1.1 Introduction
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 RS-485 output and dual process control relays. These
adjustable setpoints allow control of valves, switches, alarm signals, or
other controls.
