Wireless Portable Vehicle Weighing System



RWP-750A is a wireless portable vehicle weighing system, no connection cable is needed.
Being wireless transmitted between the detectors and the indicator, enables to reduce preparation time as well as improving the flexibility of layout. Good-diffraction radio band 920 MHz is used for communication. The antenna is built into detectors, therefore hard to damage even run over by vehicles.


· IP67 (IEC 60529)
· Integrated detector slope
· USB memory for data transfer to PC


· This weighing system is the specified measuring equipment as provided in the Measurement Law in Japan. (But it is not included in products requiring qualification.)
To ensure safe usage, periodical maintenance and calibration are recommended.
· Since it is a simplified system, the accuracy differs depending on the measuring place and method. Thus, it is not intended to provide a certificate in commercial transaction.
· Temperature range of indicator for battery charge is 0 to 40°C.
· The system does not conform to any overseas radio laws. Use it in Japan.
