AAV003-10E is a highly linear, extremely low hysteresis GMR current
sensor with an on-chip current strap. A GMR bridge sensor element close to the current strap senses the magnetic field created
by the current. The GMR sensor element uses a unique, bipolar output
low hysteresis GMR material. The bridge output voltage is bipolar and
proportional to the current through the strap.
Typical sensitivity is a remarkable 2 mV/mA with a 24 V supply and no amplification.Key specifications are summarized as follows:
General purpose current sensor, ±80mA --
Provides bipolar output for AC and DC currents up to 80mA
Current Measurement Range
-80 mA to +80 mA
Low Current Measurement
Note: Parts must be purchased in tube multiples (increments of 100) when purchasing quantities of 100 or more. Larger quantities are subject to NVE's standard lead times.
This demonstration features the ALT025 low hysteresis, high-speed TMR magnetometer and a high current PCB layout, optimized for the detection of +/- 200 amps. The board has sturdy screw terminal connections for current input, and it has header pins for sensor power and output.
The AG953H-07 demonstrates high current measurement with the SM225-10E Smart TMR Magnetometer. A 1/4" x 1/2" busbar is mounted to the PCB, and the sensor can detect up to +/-650 amps. Based on the AG953-07E Evaluation Kit, a powerful, intuitive graphical user interface allows the user to control sensor offset, calibration, filtering, and memory.
