Measurement electronics
Evaluation, safety, and control for force transducers of every kind, from simple cutoff to fully configurable plant control.
Measurement amplifiers
Convert the voltage signal of a strain-gauge bridge sensor (0.5…2.5 mV/V) into a noise-resistant current-loop signal (4…20 mA). Special variants convert to digital signals such as Profibus, CAN bus, or IO-Link.
Overload protection
Analogue overload protection (R-03xx) for simple cutoff: strain-gauge bridge input, current-loop output to the PLC, up to two configurable relay contacts for overload or slack-rope detection.
Digital overload protection MVD-0485 and the memory-configurable controller SKS-0586 provide up to 22 monitored safety relays, 16 digital switching inputs, eight I/O slots for current loops, and an RS-485 connection. Configuration via display and buttons or via free PC software. The feature set covers load spectrum counter, total-load and radius calculation, cross-comparison, load-curve calculation, and self-diagnostics.
Load spectrum counters
For residual-lifetime determination per FEM 9.511, the calculation basis for series hoists.
Picking the right device for the installation
A simple winch is often well served by an analogue overload protection; more complex plants with multiple hoists usually call for digital controllers. Every device is pre-configured to your specification before shipment.
