TMR Current Sensor
Automotive TMR Current Sensor - integrated busbar
Piher Sensing Systems launches a TMR current sensor that generates a ratiometric analog output voltage signal proportional to the current flowing through the integrated conductor. Compared to conventional Hall-effect current sensors, this sensor provides more accurate measurement, a higher sampling rate and lower temperature drift. It has been designed for accurate measurement of currents in automotive battery management and motor control applications.
Specifications
- Current transducer based on TMR technology
- Up to ±4,000 A
- Fastening ready
- Analog ratiometric output
- Non-intrusive technology
- Galvanic separation between power and control
- Immunity to common mode fields
