- Ar-i7000+ (SSWIM) Indicator is a state of the art, scalable, intelligent, accurate and high-speed real-time system that interfaces to load-cells banks to extract axle weight, speed & spacing information of axles passing over the weigh-bridge.
- Ar-i7000+ used by our OEM customers is approved for SSWIM applications (up to 20 KMPH) by Govt. Of India.
- Indicator capable of interfacing with load-cell based sensors as well as bending plate sensors.
- The indicator is designed to seamlessly plug-in to the next higher level application software (Toll Management software).
- Additional customization to cater to a specific need is possible due to its scalable and reconfigurable hardware and software architecture.
- Designed in India
