(1) Different working methods. The wing gate is operated by a motor, and the three-roll gate (except fully automatic) is a combination of optical coupling reset + mechanical reset and manual propulsion;
(2) Different opening time Due to different working mechanisms, the opening speed is also different. The opening and closing time of the wing gate can basically be controlled at about 0.5 seconds, while the opening and closing time of the three-roll gate is about 1 second.
(3) The passing time is different because of the different shapes, so the wing gate is open when it is open, and the personnel can pass quickly. The fastest speed can reach 1.5-2 seconds/time, and the maximum speed of the three-roll gate (actual calculation). 2.5-3 seconds/person
(4) Channel function The passages of different wing gates can pass through small suitcases and other items (trailing), but the three-roll gates are not allowed;
(5) Different costs Three roller gates are entry-level channel products, and can only be used for civil-grade channels, while wing gates are intermediate products that can support high-traffic places such as civil-grade rail transit, and the price is several times higher. .
(6) Different performances The three-roll gate is a primary-discrimination device. It only has the role of guidance and does not possess security. The wing-bearing has functions such as anti-climb alarm, anti-trailing alarm, and anti-clamping electronic eye. It belongs to a product with a relatively high safety level. .
Shenzhen Zhongyi Channel provides you with first-class access gates, wing gates, swing gates, three roller gates, and fast track gates. If you need to purchase, please contact customer service on the website or call the hotline to order. We are looking forward to your arrival.
High Precision Optical Glass Window
Windows are optical glass with ground and polished faces that are relatively parallel.They are used to isolate two physical environments while allowing light to pass.Windows made of BK7 material have high transmission in the visible spectral region, do not scratch easily, do not degrade under normal operating environment and hence do not need any special precaution or treatment. Anti-Reflective Coating will provide higher transmission.
China Star Optics offers all types of windows made from different materials. Such as N-BK7, Fused silica, sapphire,CaF2, Silicon, Borofloat, high borosilicate glass and other optical glass supplied by Schott and Chinese CDGM are available upon request.
Windows at shape of round,quadrate, triangular or other polygonal are also available upon request.In addition, we provide a variety of single layer or multiplayer anti-reflecting coating,HR,PR coatings on Optical Windows.
