Applied Measurements was recently commissioned by bus and coach manufacturer Plaxton, part of the Alexander Dennis group, to design and manufacture a system for measuring the centre of mass of a bus. Determining this factor is a critical part of vehicle design and engineering, ensuring that buses and coaches have excellent stability while in motion.

The ET24 telemetry loadcell is designed for under-hook and lifting-gear weighing applications and can be used with any standard lifting shackles. This wireless telemetry system can be used as a single-channel setup, using one sensor and display, or for multiple loadcells in a single application. 

In the case of Plaxton, a multi-channel system was set up using two ET24-5T and two ET24-12T telemetry lift link loadcells, two inclinometers (angle sensors) and a T24-BSu base station. ET24 telemetry loadcells were attached to each corner of the bus to monitor the load and the two inclinometers were used to measure the incline.

Once the bus was lifted, instantaneous measurements were picked up by a T24-BSu wireless telemetry base station and the data was transmitted straight to a PC or laptop. 

Key benefits of product application

  • The T24-BSu USB base station receives the data from the telemetry loadcells and relays it to a PC or laptop via the USB port. This simple USB connection means no additional wires are required as the power supply is drawn directly from the USB port. The T24-BSu base station configures the telemetry system using the free user-friendly downloadable T24 Toolkit software, which offers basic logging to Excel.
  • As Plaxton required readings from multiple telemetry loadcells, its system was configured using T24Log24 software. The T24Log24 software has enabled engineers to view and log up to 24 channels of data simultaneously throughout the test and has made it possible for Plaxton to analyse the information later.
  • Further benefits include: wireless transmission up to 200m, with no cables required; multiple loadcells can be used in a single application; immediate simultaneous readings can be achieved; and the user can obtain high-accuracy outputs ±0.3 per cent of the reading.
  • The free, user-friendly T24 software allows the user to view, log and download the data to csv file for manipulation in excel.
  • Easy USB connection is provided from the T24-BSu base station to a PC or laptop.
