Current sensors

Current sensors are electronic components for the precise detection of electrical currents in cables or circuits. They detect the current flow in real time and convert it into a measurable output signal - either analog or digital. A frequently used principle is shunt technology: the Sensor measures the voltage drop via a low-impedance measuring resistor and calculates the current from this. Modern current sensors are often temperature-compensated and calibrated to provide reliable values even under changing environmental conditions. This technology is used in areas such as industrial control systems, e-vehicle charging stations, battery monitoring and renewable energy systems. Bourns' current sensors are particularly robust, compact and easy to integrate into existing systems. Rotima AG is an experienced distributor of current sensors for a wide range of industrial requirements and offers technical advice on the selection of suitable models for specific applications.

Current sensors are essential for monitoring and controlling battery systems, especially with lithium-ion technology. They continuously measure the current consumption and output in order to accurately record the state of charge and the load on the cells. This data is crucial for preventing overcharging, deep discharging or thermal overload - all factors that can have a major impact on the service life of the battery. In modern battery management systems (BMS), current sensors therefore serve as safety-relevant components. They enable the exact control of charging and discharging processes and are therefore a prerequisite for safe and efficient operation, both in stationary storage systems and in mobile applications such as e-vehicles. As a distributor, Rotima AG offers high-quality current sensors from Bourns, which have been specially designed for use in energy storage systems and are characterized by precision, robustness and simple system integration.

Current sensors play a central role in EV charging stations, as they precisely detect and monitor the flowing charging current. They ensure that the current flow remains within the permissible range and enable even load distribution - especially in charging parks with several charging points. Precise measured values are also essential for billing the amount of energy charged.

In addition, current sensors help to detect overcurrent situations and trigger appropriate protective mechanisms. This is particularly important for fast charging stations, where high currents flow within a short period of time. The Sensors must therefore not only be accurate, but also thermally stable and reliable. Current sensors from Bourns meet these requirements and can be integrated directly into the charging electronics thanks to their compact design. Rotima AG supports customers from the electromobility sector in selecting suitable current sensors for DC or AC charging stations - including advice on the optimum configuration and interface.

Current sensors with shunt technology are considered to be particularly precise, robust and cost-effective. The mode of operation is based on measuring the voltage drop via a known resistor (shunt) through which the current is conducted. This method enables very accurate detection of the current flow, even at high frequencies or rapid load changes.

A major advantage is the ease of integration: shunt-based current sensors can be easily integrated into existing conductor paths or printed circuit boards. In combination with digital signal conditioning, as used in Bourns current sensors, the result is a temperature-compensated and calibrated solution that can be integrated directly into control units. Rotima AG distributes these high-quality shunt current sensors and offers customized solutions for industrial control systems, energy management systems and automation technology. Customers benefit from high measurement accuracy, durable design and flexible interfaces.

Current sensors

have become an indispensable part of modern industrial automation. They detect currents in real time and thus enable precise control of processes. Typical areas of application are motor controls, converters, control cabinets, battery systems, power supply units and monitoring units in power distribution systems. In manufacturing and drive technology in particular, current sensors help to detect machine conditions, control loads and identify faults such as overloads or short circuits at an early stage. They also play a role in predictive maintenance, as they detect changes in condition through continuous measurements. Current sensors from Bourns have been developed to meet these requirements and are characterized by their high bandwidth, precise measured values and robust design. Rotima AG supplies these sensors to industrial customers throughout Europe and advises on selection, installation and application - even for individual technical requirements or complex system environments.
