The NA1000FD Gas Detection and Alarm Instrument is based on the technical principle of a dual-wavelength non-dispersive infrared spectrometer (NDIR) and is equipped with high-performance sensors. It can simultaneously conduct real – time monitoring of sulfur hexafluoride, oxygen, temperature, and humidity in the current environment, display the measurement data in real – time, and transmit the monitoring results to the DCS or the host via RS – 485 or Zigbee signals. Meanwhile, it compares the results with the set alarm values. When the alarm conditions are met, the audible and visual alarm will go off, enabling the staff to promptly detect SF6 leakage and oxygen deficiency and take corresponding measures according to the on – site situation.
It uses an OLED display to show the current measured concentration information in real – time.
Users can set the alarm values of the measured gases independently according to the characteristics of the measured gases and on – site requirements.
The measurement data, instrument configuration information, and relay status can be remotely transmitted to the host via RS485 or Zigbee.
After power – on, the instrument automatically checks the configuration information (including sensor installation information) and compares it with the factory – set configuration information to determine if there are any sensor faults.
It can upload the configuration information to the host via the RS – 485 bus and has a fault diagnosis function.
The instrument can be calibrated on – site through key operations or remotely calibrated via the host.
It has obtained the EMC Industrial Level 3 Certification.
