LY-NDVIS Non Dispersed Visible Gas Measurement Optical Module Introduction: The LY-NDVIS transmission smoke meter module is a high-performance smoke meter module independently developed by Laoying, which can meet the technical requirements of standards such as JJF 1482-2014 and JJG976-2010. It has three readings: opacity N, absorption coefficient K, and effective length absorption ratio Ns of the standard optical channel, and supports functions such as N value calibration and smoke temperature calibration. characteristic: Accurate measurement of opaque parameters, reliable and stable performance, meeting national standard requirements Built in precise and reliable temperature control system, capable of working under different environmental conditions, with low maximum and average power Small size, light weight, simple interface, and high integration characteristics. Technical parameters: measuring range Opacity (N): 0-99.9% Light absorption coefficient (K): 0-16.08m-1 Flue gas temperature: 0-150 ℃ Indication error Opacity (N): ≤ ± 2.0% Light absorption coefficient (K): ≤ 0.05m-1 Flue gas temperature: ≤ ± 2 ℃ Resolution Opacity (N): 0.1% Light absorption coefficient (K): 0.01m-1 Flue gas temperature: 0.1 ℃ Drift: ≤ ± 1% Repeatability: ≤ 1% Response time: ≤ (1.0 ± 0.1) s Effective length of optical channel: 0.215m Maximum power:<65W Average power:<30W Communication interface: RS-485 Communication protocol: Modbus
