485 type tunnel visibility detector SD-N01-VL
I. Product Overview
The tunnel visibility detector SD-N01-VL is a device used to measure the visibility inside the tunnel, for monitoring and evaluating the visibility conditions inside the tunnel to ensure the safety of vehicles and pedestrians when they are traveling in the tunnel. The tunnel visibility detector can simultaneously detect attenuation coefficient, transmittance, carbon monoxide concentration, and temperature and humidity factors. It adopts the transmission principle, is powered by 220VAC mains electricity, has an automatic compensation function, which can compensate for the numerical deviations caused by equipment aging and dirt; it uses modulated light signals to reduce visible light interference. It has a one-channel passive relay alarm, multiple signal outputs, one 485 signal, two analog signals, can be connected to the network platform for real-time monitoring via 4G signal, supports Bluetooth configuration, and can read data or set parameters through the mobile phone APP.
II. Product Features
1. High stability: Industrial-grade electronic components, strong anti-interference ability, long lifespan and high stability.
