Description

The PR 6201 range of load cells is specially designed for weighing silos, tanks and process vessels.
Product profile

The PR 6201 range of load cells is specially designed for weighing silos, tanks and process vessels.The unique design principle, in combination with the FlexLock installation kits, makes it possible to counterbalance movements arising from mechanical or thermal expansion or contraction of the vessel or its supporting construction.A particular design characteristic is that the overall height and shape of the load cell remain unchanged, even after two decades of use. Alongside this, the unit has an especially high overload capacity of up to 200%. 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 pendulum support principle, combined with patented measuring element geometry, ensures that force transmission into the sensor is always at the optimum level and, in this way, the effect on measurement accuracy is minimized. At the same time, the load cell offers a particularly high overload range, high repeatability and perfect linearity.There is an especially wide working temperature range attributable to special resistance strain gauge technology. The hermetically sealed enclosure and special TPE cable allowthe 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.
Restoring force

For each mm of displacement, that the top of the load cell is shifted from the vertical axis, a horizontal restoring force of 0.5% of the applied load is generated.
Load cell housing

Full stainless steel housing, membrane and measuring element hermetically sealed, welded, filled with inert gas.
Material-No

1.4301 (DIN 17440), equivalent to 304 S11/S15 (B.S.)
Ingress Protection

IP 68, IEC529 (equivalent to NEMA 6). The load cell can be submerged in water to a depth of 1.5m for 10,000 hours.
