Convectron ATM Vacuum Gauge Module Instruction Manual
Chapter 2
The Convectron ATM module contains a Convectron convection-enhanced
Pirani heat-loss gauge and a Piezo resistive diaphragm sensor.
Using the module to measure the pressure of flammable
or explosive gases can cause a fire or explosion resulting
in severe property damage, personal injury, or death.
Do not use the module to measure the pressure of flammable or
explosive gases.
The module is shipped with an instrument screwdriver and a 15-pin female,
high-density subminiature D connector that mates to the male connector on
the module.
Figure 2-1 illustrates the analog version of the module. In the analog
version, setpoint relay 1 is assigned to the Convectron gauge, and setpoint
relay 2 is assigned to the differential pressure sensor.
