The twistlock sensor system is used for weight measurement on spreaders and, with that, the weighing of containers prior to loading and also the determination of the weight distribution in the container.

The non-measuring twistlocks in the spreader are replaced by the twistlock sensor system (TWLMS). The system consists of the model F9205 twistlock sensor, fully assembled in the factory in the customer-supplied and pre-drilled twistlock, including adjustment and temperature compensation.

The twistlock sensor of this system is made of high-strength, corrosion-resistant 1.4542 stainless steel, whose properties are particularly suitable for the transducer’s application area. As output signals, there is a choice of active current output (4 … 20 mA) and CANopen® and CAN SAE J1939 digital outputs.
