Description

SLC611D POWERCELL® PDX Load Cell

The SLC611D POWERCELL® is approved for use in various applications in Europe, Asia, America and almost everywhere else in the world. If an approval is required, the SLC611D POWERCELL® already complies.

Tank Weighing
The capacity range from 7.5t to 22.5t allows the weighing of tanks and silos. The stainless steel design, hermetic sealing and IP68/IP69K protection provides the best reliability in tank and hopper weighing applications.

Load Cells
POWERCELL® load cells have a rocker-pin design that automatically aligns load forces for accurate weighing. These hermetically sealed load cells are rated IP68/IP69K and can be used in all environments.

PowerMountTM Weigh Module
The optional METTLER TOLEDO PowerMountTM weigh module allows one to convert an existing system into a precise weighing system. It is ideal for applications such as tanks scales, belt scales and conveyor scales. Available in zinc plated steel or stainless steel.

Predictive Maintenance
SLC611D monitors single load cells for overload, zero drift, foundation problems, etc.; prompting action before system shuts down or measures incorrectly.

1 R.C. = Rated or full capacity as specified on the data plate.
2 Certified according to approval agency or notified body (third party).
3 Operating temperatures below -40°C/-40°F require the load cell to be continuously powered.
4 The combined error of span, linearity error, and hysteresis will not exceed 80% of the error limits for OIML R60. OIML R60 C3 error limits are typically 60% tighter than the HB44 10K III L-M allowable tolerance.
