When weighing applications demand a rugged high-capacity load cell that takes up minimal space, the 300 Series from Richmond Industries is tough enough and small enough for the job. Available with standard ranges up to 0-200kN, these compact button-style load cells are ideal for heavy-duty tasks such as measuring loads on bearing supports, structural monitoring and silo weighing.
Lower capacity devices come with a tiny 32mm-diameter circular footprint and a low profile of just 25mm. And even the largest load cells in the series measure just 50mm diameter by 55mm high.
All 300 Series load cells feature onboard electrical calibration so that they can be commissioned in the field without recourse to physical standards. They are low-deflection devices, and are amply protected against overloads, tolerating 150% of rated load with no loss of calibration, and at least twice rated load without structural failure.
Accuracy is respectable for such high-capacity devices, with maximum combined nonlinearity and hysteresis errors of just 0.3% of full-range output and a sensitivity of 2.0mV/V +/-0.05%.
Easy integration is ensured by a generous 2m-long integral screened cable (with other lengths available by special request) and an optional loading pad to ensure the forces to be measured are fully centred on the load cell.
The operating temperature range is a generous -20 to +70C as standard (with even wider ranges available), ensuring that the 300 Series can be used in outdoor applications in a wide range of climates. Temperature compensation is provided between +20 and +70C as standard, and this can be extended for extreme applications. Also, devices can be supplied with fully traceable NAMAS calibration.
