Various coil systems and highly sensitive field sensors may be used for the calibration of novel magnetic sensors.

Some total field sensors give different readings depending on their orientation.

It was to carry a TV camera and a magnetic field sensor.

Magnetic field sensors detect vehicles passing over them and not necessarily stationary vehicles.

Portable field sensors can screen air samplings and give an initial analysis within 15 minutes, he said.

The Hall effect is used in magnetic field sensors, present in a large number of devices.

The last fake jewel, an electrical field sensor, registered nothing, not even any activity in the electrical gear around it.

And it was eating more; Mother's wide field sensors sensed more being absorbed every few seconds all along the massive interior.

The electric field sensors of sharks are called the ampullae of Lorenzini.

To measure the field below the geomagnetic noise, much more sensitive magnetic field sensors have to be employed.
