- Model CDA - Incinerator for Measuring Gas Temperature

Advanced non-contact infrared thermometer designed for measuring the gas temperature within waste incinerators. The CDA thermometer is optimised to accurately measure the gas temperature in waste incinerators using AMETEK Land’s unique non-contact infrared technology. CDA ‘sees’ through a cold ambient air to measure the hot carbon dioxide beyond. By filtering out other gas types, CDA provides a true gas temperature for exceptional control - improving both process safety and process efficiency.

Installed in an incinerator, the thermometer works as an ‘invisible thermocouple’, with its sight path extending above the furnace bed. With a simple two-wire loop connection and standard 4-20 mA signal output for easy connectivity, CDA ensures no interference with the process, ensuring an accurate measurement and high reliability. 

CDA is intended primarily for measuring gas temperature in waste incinerators. It can also be used to measure furnace gas temperature in power generation and industrial processing applications, provided the path length is sufficient. 

Resilient and Accurate Measurement
Insensitive to the presence of gases other than hot carbon dioxide, CDA delivers a highly stable, true gas temperature.

Compatible With System 4 Accessories
CDA fits our standard System 4 mounting accessories, air-cooled or water-cooled protection jackets, and air-purged sighting tube. This means there are no compatibility issues when using these attachments which provide excellent protection in harsh environments.

Minimal Maintenance Required
Fitted externally, the thermometer sight path extends into the incinerator atmosphere to a depth which depends on atmospheric conditions. This ensures no interaction with the combustion process and reduces maintenance requirements for the thermometer.

The CDA thermometer is AMETEK Land’s non-contact solution for measuring gas temperature in waste incinerators.
