• New smart sensors are recognized by the AMC-DTR and prompts users to either upload
new configuration data or continue with data from the previous smart sensor.
• Sensors are industry proven for fast response and long life.

4.3 Sensor Location
Factors such as air movement, gas density in relation to air, emission sources and
environmental variables affect correct sensor location. Air movement by fans, prevailing winds
and convection should be carefully evaluated to determine if a leak is more likely to raise gas
levels in certain areas within the facility. Vapor density of a gas determines if it will rise or fall in
air when there are no significant currents. Lighter than air gases should have the monitors
mounted 12 – 18 inches (30 – 45 centimeters) above the potential gas leak and heavier than air
gases should be this distance below. Even though the AMC-DTR is designed for rugged
service, sensors should be protected from environmental damage from water, snow, shock,
vibration and dirt.
