METTLER TOREDO / SLP33xD-IOL / Smart Load Cell

High-Quality Aluminum Alloy Single Point Load Cell with IO-Link Connectivity

• Integrated connectivity saves space, reduces system complexity, and allows quick and straightforward installation.
• CalFreeTM technology provides factory calibration data, so the load cell is ready to measure.
• TwinCalTM delivers high accuracy for both loading and unloading applications.
• Smart5TM intelligent condition monitoring and alarms ensure easy maintenance and high machine uptime.
• Direct connection to PLCs, DCSs and to other host controllers and the IODD file ensure rapid integration into any kind of machine, thus development time is reduced.

설명

SLP33xD-IOL Smart Load Cell

Integrated Connectivity
PLC connectivity is integrated in the load cell; no additional device is required. This saves space in the machine and/or in the control cabinet and reduces complexity, so that you can streamline sensor integration without expert knowledge.

High Precision
Load cells are available with OIML C6 and C3 class. TwinCalTM calibration technology supports loading and unloading applications. Onboard filtering and adjustment for temperature changes enable precise weighing results.

High-Speed Weighing
The load cell provides 200 updates per second (200 Hz), which supports highspeed weighing applications. Machine designs can be optimized for high throughput and increased productivity.

Advanced Intelligence
Condition monitoring and Smart5TM alarms ensure the system is performing as expected and allow quick reaction in case of issues. Achieve a new level of confidence in your machine performance.
