MAXREFDES82#

The MAXREFDES82# is a smart force sensor system board. Mounted on a quadrant of load cells channelled into a multi channel, 24bit analogue to digital converter (ADC), MAXREFDES82# senses weight and centre of mass for objects placed on the platform. The scale provides full scale responses up to 780g. The user interface provides an active display of centre of mass on the platform as well as total measured weight. In addition to serving as a smart force sensor, the design works very well as a ruggedized touch interface with force sensing. This compact next generation industrial smart force sensor board is designed in a compact form factor for rapid evaluation or installation. This reference design features the MAX11254 24bit, 6-channel, 64Ksps delta sigma ADC with SPI interface and design uses STM32F429 processor which controls ADC, LCD module and performs all computations.

• Rugged, cost effective, flexible 3D human interface input device
• High precision, high resolution measurements
• Fast, low power data acquisition
• Built with plastic plate, system ideally meets needs of industrial human machine interfaces (HMI)
• TFT LCD digitally shows forces on each individual load cell & total force applied on the top plate
• Consumes minimal energy and powered by USB port
• PC side GUI program to facilitate the human interface input demonstration and development
• Consumes less than 50mA during normal operation
• USB interface for quick evaluation and integration
