TENSOMETRIC SENSOR PR6211

The PR 6211 range of load cells is specially designed for weighing silos, tanks and process vessels.

Due to its high strength it is ideally suited to work in difficult and demanding technological conditions, guaranteeing reliability. Thanks to the hermetic housing in the IP68 standard, these sensors can operate in a wide temperature range and without loss of measurement parameters, they withstand overload of up to 150% of the nominal load. The offer also includes a sensor version for use in the potentially explosive zone (operating range: 500kg to 10t) and a version for working in high ambient temperature (operating range: from 500k to 5t).

Application:

• Platform scales
• Tank scales
• Weighing crucibles / furnace at high temperature
