Dwyer Instruments has released its Carbon Dioxide Transmitter Series CDWP. The CO2 Transmitter can be utilized to monitor the carbon dioxide concentration in applications such as HVAC and CO2 refrigeration mechanical rooms. This Carbon Dioxide Transmitter uses a single-beam dual-wavelength NDIR sensor which eliminates light source aging affects. The Series CDWP is available in multiple range limits and comes standard with universal outputs of 4 to 20mA and 0 to 5 or 10 VDC, for use with most programmable logic controllers or building management systems.
The Series CDWP utilizes a new IP54-rated housing which protects the electronics from dust and splashed water, while the powder painted die cast aluminum housing is an improved material over polycarbonate housings. This Carbon Dioxide Transmitter can be configured with either a wall mount or hang suspension bracket. The company claims the field-replaceable vent and lid allow customers to change the filter quickly and easily, even in harsh environments.
