Latest weighing device provides 10,000 divisions

New weighing electronics from HBM enable digitization without any loss of information, enabling certification as Class III weighing machines with the maximum permissible number of 10,000 divisions

The performance of the two devices, the AED9401A and AED9501A, has been confirmed by independent tests issued by an independent notified body.

Both devices allow strain gauge (SG) transducers to be digitally connected to standard fieldbus systems using either CANopen or DeviceNet interfaces.

The electronics can be fully PC-controlled and provide integrated, electrically isolated control inputs and outputs ensuring that they can be used for both static and dynamic measurements.

The AED9401A/9501A offers a crucial advantage for plant engineering and automation companies seeking to install a customer-specified bus system for export.

The CANopen protocol is preferred in Europe while DeviceNet systems are widespread in the American and Asian markets.

With the AED9401A/9501A both CANopen and DeviceNet can be used as interfaces, depending on the specification, with changeover via a software command.

Both devices are fitted with an array of special features including different filters, sampling rate adaptation, works and user characteristics, linearisation as well as over 100 structured commands that enable access to the connected strain gauge transducer or system.

Other features include smart optimisation functions and control functions required for repetitive processes, for example for automatic weighing machines.

Panel software suited to service, development, start-up and parameterisation are additionally available.

The system is supplied with 18 to 30 V in compliance with international industry standards.
