Onboard weighing.

Onboard Solutions & Sons is an onboard vehicle weighing specialist covering the installation, diagnostics, repair, and maintenance for load cell-based weighing systems on HGVs and other commercial trucks and trailers. From its main workshop in the industrial heartland around Nottinghamshire and with a nationwide call-out service, the Company prides itself on professional technical support gained by several years’ experience and weighing expertise including custom design and system installation. To ensure the high standards set for safety and reliability, Onboard Solutions choose load cells and mounting equipment from Zemic, the globally leading sensor manufacturer - supplied and fully supported by its exclusive British distribution partner Variohm EuroSensor.

The company uses the Zemic H10J series load cell for its commercial vehicle onboard weighing systems which include its own dash mounted or portable displays and weighing software. With optimum weighing performance achieved with the load cells installed between the load carrying superstructure (box, tank, flatbed etc.) and the vehicle chassis, the 15t capacity H10J series load cells provide the payload measurement for vehicles up to approximately 32 tonnes. Its bending beam design with nickel plated alloy steel and adhesive sealed construction has IP67 rated ingress protection to suit the harsh environment use for onboard vehicle installation. The CE certified load cell has a -35 to +70 ⁰C operating temperature range, 150% overload security and high resistance to shock and vibration, guaranteeing reliable and safe use. A detailed eight-page application guideline covering installation and use of the H10J series for onboard vehicle weighing is available on request from Variohm.

Variohm also supplies Zemic’s HM9C load cell for onboard weighing applications. This circular shaped dual shear beam model is available for load ratings to 44 tonnes and with alloy steel construction and hermetic sealing offers IP68 protection. It also features an OIML test certification and can therefore be used for commercial truck scales and other heavy weighing devices. Recently awarded a winner in the 2021 edition of the Weighing Review Readers' Choice Awards, the HM9C is typically supplied complete with a choice of optional mounts to simplify installation; for example the HM-9-401-5 series mount has a self-aligning capability and also offers significant resilience to heavy static or slight dynamic loads. For higher resistance to aggressive substances, the alternative B9C load cell has all the features of the HM9C but offers stainless steel construction.

Load cell.

The new U3 load cell, from HBM, is specifically designed for tensile and compressive forces.

Designed to address the problem of lateral forces, which if great enough, can damage or even destroy a force transducer, which can subsequently cause a drop in production, the U3 is capable of absorbing up to 100% of rated forces in the form of lateral force, without losing its measurement capability, or sustaining mechanical damage

Featuring a double-sided flange connection, which allows the sensor to be mounted quickly and easily, in order to minimise downtime, the U3 is suitable for use in a range of applications in production and monitoring.

With capacities ranging from 0.5 kN to 100 kN, the U3 is an extremely robust load cell which is housed in stainless steel casing, corrosive resistant and is IP65 protection rated.

Load cell technology in Antartica!

Mantracourt Electronics’ miniature load cell and strain gauge amplifier (ICA4S) was chosen as a key component in a project to build a drill that recently extracted a 763m ice core from the Ross Ice Shelf in western Antarctica. The research from the study will build a better picture of atmospheric greenhouse gases, sea level and temperature change over the last 20,000-40,000 years.

For this project, Mantracourt’s ICA4S load cell amplifiers have been incorporated into a pair of load pins to provide a 4-20mA output for the monitoring of drilling forces during extraction.

“The drill system is now into its third year of service on the ice,” said Louise Stubbs, Marketing Coordinator at Mantracourt. “This project is a very good test of our technology, with extreme temperatures and a rigorous demand for accuracy and reliability.”

The ICA range of miniature load cell signal conditioners offers a high performance strain gauge amplifier in miniature OEM format, designed specifically for fitting inside load cells, thereby converting a standard load cell to a 0-10 volt or 4-20mA output.

The ICA family offers high stability and fast response and is available in 6 versions with two performance categories S & H (industrial & very high stability). The ICAH range offers very low drift over wide operating temperatures. There is also an ATEX certification available on one version of this device.

“The Mantracourt aspects of this project were supported by our UK based Technical Partners, Applied Measurements,” said Louise. “Mantracourt works with a number of Technical Partners around the world to ensure our technology is backed up by the highest level of customer service and technical support.”
