...with analog gain setting capacitors or resistors. Figure 1. The magnetic sensor ASIC reduces the design and calibration costs associated with more conventional analog devices such as Hall effect sensors. The digital-based circuitry uses an inductive resistor (LR) oscillator to convert sensor signals...

AN650. INTRODUCTION. WORKSHEET 1: INITIAL COIL. Overview of Inductive Communication. SPECIFICATION. Communication between a K. ®. EELOQ transponder and. Data Required. a base station occurs via magnetic coupling between. The first step is to decide on the dimensions that the. the transponder coil...

...and tag coils. The mutual coupling between the. induced current will oppose the original magnetic field. two coils is maximized in the above condition. The magnetic flux Ψ in Equation 4 is the total magnetic. field B that is passing through the entire surface of the. antenna coil, and found by: FIGURE...

...is a patented technology that exploits the unique nonlinear magnetic signals of superparamagnetic materials embedded in magnetic beads (see Figure 1). Unlike conventional methods that measure the susceptibility ( x) of superparamagnetic materials, MIAtek measures only the nonlinear impact on a magnetic...

...approaches to the coil format and are described in this section. LVDT and Half-Bridge transducers convert the movement of a core within the magnetic field produced by an energised coil into a detectable electrical signal. Conventional Half Bridge. The Half Bridge transducer forms half of a Wheatstone...

...is supported by low-friction bearings and incorporates electrical drive coils in a lightweight polymer. The forcer surrounds the thrust rod, and is propelled along the thrust rod�s length by digitally controlled magnetic fields. Tools for holding slides and test tubes are mounted directly onto...

magnetic flux paths are rod cores and unshielded bobbin cores. CORE LOSSES. Core losses are caused by an alternating magnetic field in the core material. The losses are a function of the operating frequency. and the total magnetic flux swing. The total core losses are made up of three main components...

...the emitter coils are activated with a high frequency AC. field and produce an inductive RLC circuit with the posi- to the resonator kCOS and kSIN vary sinusoidally along the. tioning element. The element is inductively coupled with measurement range. Since the sensor coils are balanced,. the receiver...

...operating range. Inductive sensors are well suited for detecting metallic objects in machinery and automation equipment. Some inductive sensors are inherently immune to magnetic field interaction, making them useful in applications where alternative technologies would fail due to interference...

...mode, magnetic-signal frequency response through the audio band. T-coil mode, magnetic-signal and noise articulation index. The hearing aid must be measured for RF immunity in microphone mode. RF immunity in T-coil mode. T-coil is an abbreviation for telecoil, an inductive coil used in some hearing...
