Shear beam load cell

28 June 2017

Central to agricultural machinery specialist Van Hees’ automated BOXFILR system for handling vegetable produce is its ´Bunker Filler´, produced as a single or much higher-throughput double module.

This machine can fill a crate in seconds, with a throughput of up 100t/hr. With in-situ weighing added to the machine, this removes a downstream procedure - optimising operation and reducing time and cost.

ZEMIC, represented in the UK by Variohm EuroSensor, specified its BM8H series shear beam load cell for this application. The IP68 rated load cell boasts an OIML R60 C3 accuracy class in six selectable capacity options from 500 kg to 5t. The durable design includes a hermetically sealed stainless steel case.

To further automate the weighing process on the BOXFILR, a ZEMIC Top-Sensors T1 weight transmitter is connected to the BM8H load cell and the produce weight information sent to the main control unit. The DIN rail mounted transmitter includes a 7-segment display and is available with a wide choice of output configurations including analogue (voltage and current) as well as USB and fieldbus protocols for Profibus DP, Ethernet/Modbus TCP/IP, CANopen and Profinet. An RS485 serial port provides connection for PC/PLC and 3 outputs/2 inputs may be used for machine interaction.

Variohm EuroSensor supports the full ZEMIC range with comprehensive technical support and service with stock delivery available for standard load cells as well as a custom design/modification capability and integration with other Variohm sensor technologies.
