Introduction

The WheelRight Weight and Pressure in motion WR100 or WheelRight Weight in motion WR120 system is an instrument used for dynamic axle weighing of road vehicles in motion and can also be used to determine tyre pressures (not covered under this approval). The weighing system shall be installed to manufacturing guidelines in a controlled weighing area where vehicle speed is controlled, and shall adhere to the installation requirements of OIML R134- 1:2006 (E) or any later versions. The instrument is to be used for the determination of gross vehicle weight only.

The conformity was established by the tests and examination described in the associated pattern evaluation report P01010/R134 which includes 12 pages.

Characteristics of the instrument:

Indicator type and devices:

This instrument utilises the following digital indicating devices designated the WheelRight Sensor Interface Board. The above named indicator has the following features:

• Zero tracking ( $ \leq 4 % $ Max)

• LCD or LED display

• Printing

• Vehicle Identification System (ANPR or RFID)

Interfaces:

The instrument may have the following interface type:

RS-232

RS-485

USB

Ethernet

• Bluetooth

WiFi

Load cell:

Any compatible load cell(s) may be used providing the following conditions are met:

• There is a respective OIML Certificate of Conformity (R60) issued for the load cell.

The certificate contains the load cell types and the necessary load cell data required for the manufacturer's declaration of compatibility of modules, and any particular installation requirements. A load cell marked NH is allowed only if humidity testing to R134 has been conducted on this load cell.

• The compatibility of the load cells and indicator is established by the manufacturer by means of the compatibility of modules calculation at the time of verification.

• The load cell transmission conforms to a standard type.
