Mantracourt has introduced its next-generation DSM (Digital Strain Module), a strain gauge digitiser designed for modern industrial and vehicle systems. The module converts traditional analogue strain-based sensors, such as load cells and torque sensors, into digital output devices. This allows OEMs to build a single, configurable communication system to support distributed sensing architectures.
The DSM is engineered to address the scalability limitations of legacy Controller Area Network (CAN-based) products as machines become more digital and software-defined.
“CAN-based communication is a protocol used in vehicle systems, industrial automation and agricultural machinery to allow for communication without the need for a central host computer,” said Robert Badcock, chief executive officer at Mantracourt, in the company's press release announcing the launch. “As a concept it’s smart, but legacy systems cannot keep up with the demands of modern industry because they are slow, vulnerable to electrical interference and complex to integrate.”
The DSM provides a direct digital output over a CAN interface, which eliminates the need for analogue signal conditioning, simplifies wiring and improves noise immunity. The single hardware platform is configurable via software, which helps to simplify integration into existing control systems and reduce product variation.
Features of the DSM include:
- Direct digital output over a CAN interface
- Support for voltages up to 32 VDC
- Selectable measurement rates up to 1000 Hz
- Compatibility with most standard CANbus networks
- Future firmware updates will extend support to J1939, CANopen and RS485
- Custom message mapping and payload formatting
- Advanced calibration modes
- Available in embedded and external formats
