communicating carbon dioxide detector

the series cdta communicating carbon dioxide detector combines the function of three room sensors into a single, compact housing. Parameters include carbon dioxide, humidity, temperature, and temperature set point with override. By having field selectable mtemperature set point with override. By having field selectable modbus and bacnet communications, only four wires are needed for power and the communication signal. The communicating detectors can be daisy chained together to further reduce installation cost. In order to reduce the set up time, the rs-485 mac address is set up using on board dip switches. A second set of dip switches are used to select whether output is modbus rtu or bacnet ms/tp communication protocols and to limit access to the set up menu. Like our series cdt carbon dioxide transmitter, the series cdta uses a single beam dual wavelength non-dispersive infrared (ndir) sensor to measure the carbon dioxide level. This technology can be used in installations that will be occupied 24 hours per day. For improved accuracy, the transmitter can be field calibrated to the environmental conditions of the installation. Also, the barometric pressure can be programmed to correct for altitude. The humidity uses a capacitive polymer sensor and the temperature is measured using a 10ko thermistor sensor. The humidity sensor is field replaceable without the need for additional calibration. Optional local and remote displays are available to display any of the parameters. For applications in which the building occupants arent familiar with co2 concentrations, the lcd can be programmed to display temperature, humidity, or temperature set point instead.

• field selectable modbus and bacnet communications reduces wiring

• replaceable humidity/temperature sensor


• physical hardware lockout


• optional remote display tool


• digital intelligent temperature compensation algorithm (ditca) corrects for errors due to self heating effects of combination wall sensors

Carbon Monoxide Transmitter

The SERIES CMT200, Carbon Monoxide Transmitter provides a field selectable current or voltage output that is proportional to the gas concentration in underground parking garages, vehicle maintenance facilities, or mechanical rooms. A field replaceable, electrochemical sensor provides accurate readings for up to 4 years with proper calibration. Field calibration can be done by using Model GCK-200CO-2000CO2 calibration gas, Model A-507A calibration adapter, and the on board span and zero potentiometers.

carbon dioxide transmitter

series cdwp carbon dioxide transmitter

ndir co2 sensor with universal outputs in an industrial housing

the series cdwp carbon dioxide transmitters accurately monitor the co2 concentration in industrial, agricultural, and indoor environments to help achieve energy savings. The ip54 die cast aluminum housing was designed for harsh environments making it ideal for animal husbandry and hvac mechanical rooms. For increased sensor life and accuracy, a single-beam dual-wavelength non-dispersive infrared (ndir) sensor is used to eliminate light source aging affects. This sensing technology provides the highest level of accuracy compared to automatic baseline correction methods, which can unintentionally shift the calibration based on co2 levels and barometric pressure conditions.

series cdx wall mount carbon dioxide transmitter

measures up to 2000 ppm, adjustable output

the series cdx carbon dioxide transmitter is a low cost and high performing co2 sensor. This product will provide immediate energy savings by functioning in conjunction with building automation systems and allowing the user to effortlessly and effectively control fresh air into preferred areas. On-demand ventilation using co2 sensors prevents energy losses from over ventilation while maintaining indoor air quality. The potential for the greatest energy saving occurs in areas where occupancy alters over the duration of the day. The series cdx transmitters utilize the patented automatic background calibration (abc) logic self-calibration system. Abc logic virtually eliminates the need for manual calibration in applications where the indoor co2 level drops to outside levels during unoccupied periods. If the transmitter is being used in an application where a building is continuously occupied 24 hours per day, then the user will permit that the abc logic feature be turned off.
