Parker 023-0475 Specification & Installation Manual

023-0475 Duct CO2 Sensor specification & installation guide

Description:

The duct CO2 transmitter uses a highly accurate and reliable non-dispersive infrared (NDIR) sensor in an attractive
enclosure with a gasketed, hinged cover for duct applications to monitor CO2 levels. The sensor uses dual
wavelength optics and LTA (long term adjustment) signal processing technology to deliver industry leading long term
accuracy and reliability. These features ensure optimum measurement stability for continual monitoring of either
supply or return air measuring.
Standard features include a field selectable output signal of either 4-20 mA, 0-5 Vdc or 0-10 V dc for the highest
versatility, programmable CO2 measurement span and easy menu operation for configuration.
Do not exceed device ratings. This product is not intended for life-safety applications.
