How to Accurately Measure Current with LEM HAL100-S for Industrial Applications

If you’re looking for a reliable and accurate way to measure current in your industrial or automotive projects, the LEM HAL100-S is an excellent choice. This hall effect current sensor from LEM is designed to provide high precision measurements while being robust enough for demanding environments.Let’s take a practical example: imagine you’re working on an electric vehicle (EV) charging station. You need to monitor the current flowing into the battery to ensure safe and efficient charging. The HAL100-S can handle currents up to ±100A with a typical accuracy of ±0.6%. According to LEM‘s datasheet, this sensor has a very low temperature drift of just 50ppm/°C, making it ideal for outdoor applications where temperature fluctuations are common.The HAL100-S uses a closed-loop principle, which means it provides stable output even when there are disturbances in the electromagnetic field. For instance, if you’re designing a motor control system, this sensor will help you maintain consistent performance by delivering reliable feedback to your controller.One of the standout features of the HAL100-S is its fast response time—just 2 microseconds. This speed ensures that any sudden changes in current are quickly detected, preventing potential damage to sensitive components.Another advantage is its isolation capability. With a basic insulation level of 2.4kVrms, it keeps your circuitry safe from harmful voltage spikes. This feature is particularly useful in power electronics applications such as inverters or uninterruptible power supplies (UPS).In terms of ease of integration, the HAL100-S operates within a supply voltage range of 12-15V and outputs an analog signal proportional to the sensed current. Its compact size also makes it easy to fit into tight spaces without compromising performance.To sum up, whether you’re building EV infrastructure, developing renewable energy systems, or upgrading industrial equipment, the LEM HAL100-S offers unmatched accuracy, reliability, and versatility. By choosing this sensor, you’ll be equipping your project with top-tier technology that stands the test of time.
