- Model E-WIM 400 - High Speed Weigh-In-Motion Systems



The E-WIM 400 has been developed for high speed axle weight measurement and classification for law enforcement applications. High speed Weigh-In-Motion systems are playing a significant role as pre-warning subsystem in conjunction with low speed axle weight measurement stations. High speed WIM systems provide weight measurement without interruption to regular traffic flow. The E-WIM 400 operates using stationary piezo-electric and inductive loop sensors that are installed into pavement. Weight measurements are provided for each individual axle, each axle group and the gross vehicle weight. The E-WIM 400 can operate either as a stand alone unit with warning lamps, or as part of an integrated system equipped with a personal computer, low speed axle scale and a high speed video camera.

The E-WIM 400 is designed with new technology, high speed, 32bit microcontrollers in 19' 3U rack form with Euro size modules those can be easily replaced as modules or device for service purposes. It is possible to transmit data up to a distance of 1km via isolated RS-422 interface and up to distance to 15m via RS-232 interface. E-WIM 400 can also communicate over the GSM network using its optional GSM modem. Used in the systems which are compatible with COST 323 CLASS B+, ASTM - E1318 recommendations.
