Magnetic liquid sensor in orthogonal magnetic fields

Sensors and Actuators A: Physical, 1997
Abstract In this paper we present a sensor set-up based on magnetic liquids and provided for devices designed to measurement and control of physical parameters as: slope, displacement, acceleration, vibration parameters, value and direction of a magnetic field, etc. The sensor is under the influence of two crossed magnetic fields; one is a continuous

MAGNETIC FIELD SENSOR

2013
This magnetic field sensor comprises: - a generator generating N magnetic fields CMi by means of at least one permanent magnet (AlphaRhoi), each field CMi having an intensity Ii in the direction of measurement, each transducer TMi being positioned inside the field CMi forming a measurement block (Bi) for which the range wherein the resistance of the ...

MAGNETIC FIELD SENSOR DESIGN

Sensor Review, 1991
The magnetic field generated or disturbed by an object is often overlooked when we need to inspect or detect it. In this tutorial Steve Macintyre describes the fundamental design principles of a range of magnetic field sensors.

Monolithic piezoresistive CMOS magnetic field sensors

Sensors and Actuators A: Physical, 2003
Abstract Two original electromechanical magnetic sensors have been developed using a fully industrial fabrication process that relies on bulk wet etching of CMOS dies. The first device uses the Lorentz force to actuate a U-shaped cantilever beam, while piezoresistive polysilicon gauges convert the beam bending into an electrical signal. A 2 μT sensor

Magnetic and Electric Field Sensors

2015
The main application for magnetic and electric field fiber optic sensors has been the electric power industry. The ability to dielectrically isolate equipment and personnel from high power provides an attractive feature in terms of safety and, ultimately, cost for fiber optic systems versus those using conventional technology.

Photonic Magnetic Field Sensor

2002
Abstract : Small, in-line polarization rotators or isolators to reduce feedback in fiber optic links can be the basis for excellent magnetic field sensors. Based on the giant magneto-optical (GMO) or Faraday effect in iron garnets, they with a magnetic field of a few hundred Gauss, (20 mT) for an interaction length for an optical beam of a few ...
