Tunnel smoke concentration detector HY-VICO10

Tunnel smoke concentration detector Model: HY-VICO10 Instrument: Tunnel is a special tube structure, because of the small space, with airtight characteristics, exhaust emissions from vehicles passing through the tunnel, if not timely and reasonable vented, CO and suspended particles cause aggregation, it will be directly related to vehicles passing through the tunnel and passengers and maintaining the safety of staff. In order for the visibility and CO concentrations tunnel around the clock effective monitoring, in order to timely start forced ventilation fan and take other countermeasures, automated VICO detector in modern transportation has been an indispensable testing equipment. HY-VICO series is designed for online collection VI / CO data to the transportation regulatory authorities to provide basis for decision making road tunnel ventilation and safe passage. After working principle HY-VICO detector according to the transmission principle to work, the transmitter and receiver mounted opposite, the use of the alignment bracket, high focused beam emitted from the optical member becomes a detection beam, the installation distance spaced 10 m, 20 m, since the dust attenuation, signal processing after the receiver for the measured values ??obtained. According to China "highway tunnel ventilation lighting design standard" requirement, mounted on top of the tunnel or the side walls. The intelligent detector lens original stain protection agency (patented technology) - to prevent dust exposure detector optical components, thus ensuring a longer maintenance cycle. The main technical parameters: Technical parameters HY-VI5 HY-VI10 HY-VICO15 HY-VICO20 visibility measurement value: m, 1 / m, 1 / km; CO concentration: ppm measurement principle light transmittance method; negative correlation measurement gas from the 5m 10m 15m 20m measuring range of 5-10 meters VI: 0--15 × 10-3 15-20 meters VI: 0--15 × 10-3 CO: 0-500ppm accuracy of ± 5% ± 3% greater than the data stored in local data storage 24 hours local data storage more than 72 hours without the instrument comes with LCD status display real-time display Ambient temperature -30 ℃ --- + 65 ℃ data port digital output: RS232, RS485; analog output: two channels 0 / 4mA ---- 20mA supply voltage 220v ± 15VAC50HZ; DC 24V, 12V power MAX: 45WMIN: 10W Protection class IP65 Installation Wall installation (mounted on top of the tunnel or side wall) devices constitute a transmitter, a receiver, mounting brackets
