Dwyer CDWP-10W-C1 Carbon Dioxide Transmitter is a reliable solution for monitoring CO2 levels in various environments. It offers a wide temperature range of 32 to 122°F (0 to 50°C) and accurate readings with tolerances of ±40 PPM + 3% of reading (2000 PPM), ±50 PPM + 5% of reading (5000 PPM), and ±50 PPM + 10% of reading (10000 PPM). The transmitter can be powered by a 16-35 VDC or 19-28 VAC source. With a quick response time of 300s (t63) for 2000 and 5000 PPM, and 2 minutes for 90% step change at 10000 PPM, it ensures timely monitoring. The NDIR sensor and IP54 enclosure rating make it suitable for various applications. It offers multiple output options, including 4-20 mA current, 0-5 VDC, or 0-10 VDC voltage. The average power consumption is 2W, with a peak of 3.75W. The transmitter has a vertical mounting orientation with electrical connections pointing downward for ease of installation.
