The NB III fixed gas detector is a gas transmitter with a 4-20 mA linear analog output and RS485 (DEGA protocol) for the detection of explosive gas leaks (hydrocarbons, solvents or alcohols), toxic, asphyxiating, refrigerants or volatile organic compounds.
With a very large number of interchangeable sensors (88 sensors available), the NB III gas transmitter covers most non ATEX classified tertiary or industrial applications. Many options are available such as a digital measurement display and a relay output card. Detailed description
the NB III fixed gas detector
The NB III version without display
In its basic version without display, the NB III detectoris a rudimentary transmitter and less expensive than buying the NB III LCD.
Equipped with 3 colored LEDs, it indicates 3 states: Operating (green), error (yellow), alarm (red). 12 months after the last calibration, the yellow "error" LED starts flashing to indicate an immediate calibration need.
The NB III with LCD display
The NB III LCD version is equipped with a screen that displays for example errors, alarm states, measured value, measurement unit, or time. It is set with a magnet for configuration and consultation of the alarm history, next calibration date, etc. This model can receive an internal 3 relay card (optional) 250V / 10A. It can therefore be perfectly suited for local applications of fixed gas detection with servo-controls.
