The introduction of mandatory container weighing starting from 1st of July 2016 requires sensors that can be installed either on a headblock of the crane or on the spreader that is lifting the container. BROSA has developed sensors that can withstand the extreme high shock loading on these installations and still provide a very high level of accuracy.
For the use in container handling equipment sensors with a high degree of shock loading and vibration resistance are required. Lifting a load requires the sensors to immediately measure and register the weight of the load. Unwanted situations, e.g. snag load loads create a huge increase of load within a very short period of time. Load sensors must be able to identify these sudden load impacts for further processing fast acting safety electronics.
Interferences from transmitting devices on in and outgoing vessels, trunked radios within the container yards or power cables and electrical drives on the machines have to be eliminated by using sensor with a high degree of electro-magnetic protection. Sensors shall pick up nothing but the load signal and transfer this to the safety system for making the lift safe and reliable.
Safety regulation have become more stringent over the past years and the tolerances for the safety systems have become smaller. Therefore only load sensors with a high degree of accuracy shall be used to monitor the static and dynamic loads. Used in parent systems according to DIN EN ISO 13849-1, which pick up the load signals, evaluate and process them, our force measurement sensors have performance level e respectively SIL 3.
A sensor is always a combination and compromise of mechanical strength and accuracy. Sensors designed for high overloads create only small load signals. The amplifiers that are installed inside the sensors therefore must have a low own noise level and a high degree of gain to amplify the signal to the requested output signal. BROSA has mastered this challenge by engineering the sensors to the latest state of the art in terms of components and performance. The sensors are not only robust in their design, they are also accurate and provide the signal in the fastest time possible.
BROSA force measurement sensors are used in a variety of applications in major container ports and terminals. The following is a small excerpt:
