The PR 6246 range of load cells is specially designed for high-precision weighing of process vessels and for high-precision dosing. Due to the fact that the container is suspended, movements arising from mechanical or thermal expansion or contraction of the vessel or its supporting construction can be counterbalanced. The load cell is manufactured entirely from stainless steel. A particular design characteristic is the compact construction with a high overload range of up to 150% and the highest accuracy class of up to C6. At the same time, this range distinguishes itself - in addition to its high measurement accuracy and repeatability - above all for its unmatched reliability, robustness and stability, which enable trouble-free operation without adjustment, year after year. The associated installation kit ensures that the transmission of force into the sensor is always at the optimum level and, in this way, the effect on measurement accuracy is minimized, whilst high repeatability and perfect linearity are maintained. There is a particularly wide working temperature range attributable to special resistance strain gauge technology. The hermetically sealed enclosure and special TPE cable allow the unit to be used even under extreme operating conditions in harsh production environments. The entire measurement chain can be calibrated without the use of a reference weight. Due to "matched output" technology, a damaged load cell can be exchanged without the need for re-calibration. This saves a tremendous amount of time during commissioning. An explosion-proof (Ex) version of this range of load cells is also available, as an option, for use in intrinsically safe environments.
