INCINERATOR INFRARED THERMOMETERS

The Ametek-Land  Model CDA for waste incinerators

CDA_incinerator_IRT-installationOnline  —  The new CDA thermometer is intended for measurement of the atmosphere temperature in waste incinerators.

The CDA thermometer can be used for gas or flame temperature measurement in a variety of other plant situations provided there is sufficient path length.

The CDA thermometer’s temperature reading is unaffected by cold CO2 so it will ‘see through’ a cold combustion atmosphere to measure a hot atmosphere beyond.

In an incinerator the CDA infrared thermometer can be pictured as an ‘invisible thermocouple’ extending into the atmosphere above the bed by perhaps 2 metres/6.5 feet (penetration depth depends on atmosphere conditions).

In use, it is fitted wholly external to the incinerator, usually to a flanged tube penetrating the wall.

Key Benefits

• The CDA thermometer fits the standard Land System 4 mounting accessories and protection jackets which can be air or water-cooled. The sighting tube should normally be air-purged.

• The thermometer operates on a simple 2-wire loop connection and outputs a 4 to 20mA signal linear with temperature.

• The thermometer reading is insensitive to the presence of gasses other than CO2 and is relatively insensitive to particulate matter in the atmosphere – i.e. it measures true gas temperature.
