TMR-Stromsensor
Automotive & Industrial TMR Current Sensor - integrated busbar
Piher Sensing Systems bringt einen TMR-Stromsensor auf den Markt, der ein ratiometrisches analoges Ausgangsspannungssignal erzeugt, das proportional zum durch den integrierten Leiter fließenden Strom ist. Im Vergleich zu konventionellen Hall-Effekt-Stromsensoren bietet dieser Sensor genauere Messungen, eine höhere Abtastrate und eine geringere Temperaturdrift. Er wurde für die genaue Messung von Strömen in Anwendungen des Automobilbatteriemanagements und der Motorsteuerung entwickelt.
Spezifikationen
- Stromwandler basierend auf TMR-Technologie
- Bis zu ±4.000 A
- Montagebereit
- Analoges ratiometrisches Ausgangssignal
- Nicht-invasive Technologie
- Galvanische Trennung zwischen Stromversorgung und Steuerung
- Unempfindlichkeit gegenüber Gleichtaktfeldern
