Dwyer Instruments introduces the new Series CDTA communicating carbon dioxide, humidity and temperature detectors designed to combine multiple parameters in a single compact device.
The Series CDTA combination sensors enable carbon dioxide, humidity, temperature, occupancy override, and temperature set point measurements in the same device. Series CDTA sensors reduce installation and wiring cost, and also require less I/O on the controller leading to savings in additional hardware costs.
The measurements are transmitted through field selectable BACnet or Modbus communications to the building controller, allowing for transmitters to be daisy chained with other communicating sensors.
Carbon dioxide measurements are taken using the in-house single-beam, dual-wavelength Non-Dispersive Infrared (NDIR) sensor, while humidity measurements are measured using a capacitive polymer sensor and the temperature is recorded by a solid state band gap sensor.
Series CDTA sensors allow temperature set point and override to be locally configured using the buttons on the side of the detector and the optional integral or remote LCD.
