Boris Zils, MOBA Product Manager for Safety Applications, recently wrote a blog post: "Do you need somebody?" describing the functionality of the DSM Dual-Sonic Meter system.
This blog post covers how the Dual-Sonic-Meter 500 system is measuring the distance.
Watch this video to see how the DSM-500 system is working during a measurement.
It is impressive to see when obstacles are between the Master and Slave like for example a tube in the outrigger.
This is just one of the benefits the DSM-500 can offer to a customer for a high performance machine. Furthermore, it is not mandatory that the Master-Sensor and Slave-Sensor are aligned to 100%.
But where is the difference between a dynamic measurement and a safety measurement? There are two measurement methods:
• Dynamic measurement
Every sensor calculates its own length and transfers it to the parent controller of the machine.
• Safety measurement (with the parent machine control)
The DSM-500 checks by itself, whether 8 double (16) measurements are corresponding or not. The system sends the safety value and the status to the parent machine control.
In this operating mode the DSM-500 provides EN ISO 13849-1 PL(d).
• Contactless measuring system
• Measuring range: 0 – 5 m
• Resolution: 1mm
• PL(d) application / TÜV approval
• Easy integration and service handling
• No opportunity for an end customer to manipulate the system
• Daisy Chain concept for wiring
• Baud rate freely selectable 125/250/500kB
