Strain-gauge module

Filling, weighing, dosing, or conveying

Since some years, Helmholz offers its TB20 modular I/O systems, which comes optionally with CANopen connectivity. The strain-gauge module makes the system suitable for a range of weighing applications.

The strain-gauge weighing module features self-calibrating capability. It measures weight, force, or torque. Edward E. Simmons and Arthur C. Ruge invented the strain-gauge measuring principle in 1938. It is used in filling, weighing, dosing, or conveying applications. As the other input and output modules, it can be hot plugged-in.

The TB20 modular I/O system already introduced a couple of years ago is still expanding. The recently introduced strain-gauge module is configurable by means of the TB20 Toolbox. The Windows-based software tool supports the integration of modules into the system and to configure them. It is also a servicing tool to display the device’s current status, and to analyze parameter configuration and setup of errors.

The TB20-C bus-coupler module for CANopen complies with CiA 301. It supports up to 64 modules. All parameters are accessible by means of SDO services. The CANopen NMT slave interface features 24 configurable TPDOs and 24 configurable RPDOs. Synchronous scheduling of PDOs is support. Other CANopen features include Heartbeat producer and two Heartbeat consumers. Also the by CiA not recommended Node guarding is supported.
