LEM to unveil the world’s first Integrated Current Sensor with Sigma Delta bitstream output

LEM announced the launch of HMSR DA, the first Integrated Current Sensor on the market to offer a Sigma Delta bitstream output. LEM’s new product has been designed to provide a solution to industries requiring clean signals and facing significant problems in case of vibrations, electric noise and electromagnetic noise, for example.

Specific advantages of an Integrated Current Sensor with digital output include superior signal share and reduced noise as well as lower cost and a smaller mechanical footprint. HMSR DA will replace much more complex and costly alternative systems that would traditionally include a shunt resistor, a digital insulator and a power supply circuit. Having all these features incorporated into a single unit makes the HMSR DA a far more attractive option for applications where space is at a premium and minimal cost is essential.

Typical applications for the digital output unit include standalone servo drives, robotics, sewing machines, automated guided vehicles (AGVs), CNC machine tools and a range of other applications that demand high resolution output. The new HMSR DA sensor, which offers resolution of 11 to 13 bits and features a 10MHz clock, is LEM’s first step toward building a digital Integrated Current Sensor roadmap. The forward-thinking company is already working on the next generation of digital Integrated Circuit Sensors which will offer a resolution of 14 to 16 bits and a clock operating above 20MHz (more info).
