Detector operable just by pressing the button and usable in the open air even in case of rain power supply

This is a vehicle weighing scale for measuring and checking of loaded weight. It consists of the detection unit detecting weight through loaded wheels and the indicator , the printing of measurement results. The application method is setting the detection unit on the flat paved road and making preparations for measurements through cable connection indicator. Under driving mode, let front wheels drive onto and pass the detection unit at low speed as per wheel order. After all the axles pass the detection unit, print relevant axle and total weights. Different from the settable truck self-weight scale which measures weight by letting the detection unit carry the whole truck body, it can not only be used in factories, but also be set at the construction site with solid road surface for weight measurement due to its portability.It is a product developed with the help of rich experience on axle weight measurement.

●Portable and easy to set●Enables short-time measurement●Enables using on anywhere without AC●Equipped with standard printer●Having contact output for external control●Detection unit capable of simultaneously connecting with
