The System Process Controller is a multiple use device for precise weighing applications for industrial environment.
A wide range of interface options make it feasible for integration in all up-to-date automation concepts. The housing is designed for easy installation into witch cabinets, operating panels or direct at the machinery as a front-end unit. The bright weight display with 7 digits plus units and status symbols guarantees a good readability even under harsh conditions. Additional two text lines are foreseen each with 20 characters. Under the text lines function keys are arranged. The meaning depends on the application and guides the operator through the menu. The keys have a double assignment. The second level enables the operator to enter also alphanumeric characters. The System Process Controller offers the connection of an external PC-keyboard to upgrade the operation comfort in case of data entry. The System Process Controller have beside the normal indicator and weighing functions several interfaces and an internal alibi-memory as an option. The terminal function allows the dialog with a host either PC or PLC. The communication channels are:
Compression load cell from 500 kg to 520 t. They provide absolute precision for container cars and dosing systems. Made of stainless steel, they are highly resistant and also insensitive to vibrations.
The range of load cells is designed exclusively for use on road weighbridges. The unique design principle, combined with the installation kits, counterbalances movements caused by mechanical or thermal expansion or contraction of the weighbridge construction. The unique combination of the selected geometry and material/surface hardness parameters guarantees perfect rolling characteristics, high restoring forces and long-term maintenance-free operation. A particular design characteristic is that the height and shape of the load cell remain constant over various load stages, whilst there is a particularly high overload range of, in part, 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. The hermetically sealed enclosure and special TPE cable allow the unit to be used even under extreme operating conditions. Special resistance strain gauge technology, in combination with the PR6021/.. cable junction boxes, provides for demonstrably improved lightning protection. The entire measurement chain can be calibrated without the use of a reference weight. Due to “matched output” technology, in many cases electrical corner adjustment is not required. 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.
