Part No. 83165722-002 (Assembly Kit)
General
Model CY8100C in combination with Part No. 83165722-002
is an insert type CO
2
concentration transmitter used for
detecting concentration of carbon dioxide (CO

) in ducts.
This product can be used in a wide range of applications
such as monitoring of CO
2
concentration in return ducts and
the control of outdoor air intake.
Features
• Non-dispersive infrared absorption method (NDIR)
• Linear output signal in 1-5 V DC range
• Long-term stability
