The eSense Low-Temperature CO2 Transmitter is designed to measure ambient CO2 levels outdoors in any weather. The heating element maintains a constant temperature for both the sensor and air sample, giving consistent measurements over time.
The use of outdoor CO2 measurement as a baseline measure to compare against indoor CO2 levels for LEED points is referenced in the LEED standard for Outdoor Air Delivery Monitoring EQ1.2.The transmitter uses an IP65-rated housing with a built-in heater. The heater insures that gas samples entering the CO2 sensors are not only warm enough for sensing but also at the correct moisture level. The CO2 levels are then read by the NDIR carbon dioxide sensor, and transmitted via industry standard 0-10V or 4-20mA signals to an HVAC system.
The eSense uses a built-in self-correcting algorithm called ABC (Automatic Baseline Correction). This algorithm constantly keeps track of the sensor’s lowest reading over several days and corrects for long-term drift.
This device is also available in (2) other versions. The first which is designed for safety in enclosed spaces like freezers and coolers and the second which is designed to log data using UIP Software. Both are available upon special request.
