Symmetrical core improves micro-fluxgate sensors
Microfluxgate sensor with flat coil and double-sided symmetrical core has significantly improved parameters over the original asymmetric single-sided core design. The magnetic circuit of the new sensor is more closed and so the core is deeper saturated. The sensor hysteresis was decreased from 30 μT to 2.5 μT (for full range). Noise level was decreased from 242 nT to 27 nT rms (0.1 mHz to 10 Hz...
متن کاملMicro-fluxgate sensor with closed core
Micro-fluxgate sensor with symmetrical core on both sides of the planar rectangular excitation and pick-up coils has substantially improved parameters compared to its single-core predecessor. Almost closed magnetic path for the excitation field allows much deeper saturation of the sensor core, which reduces the perming effect, hysteresis and noise. Perming of max. 5 μT for 6 mT field shock, 28 ...
متن کاملMultiwire Differential Signaling
This document describes and discloses a set of ideas for improving the bandwidth on a signaling system composed of more than one wire. These ideas represent a generalization of practiced 2-wire differential signaling, widely used in computer and communications systems. The central notion is to group a set of N wires together (N > 2), allowing more than one symbol to be transmitted on the wire-s...
متن کاملCurrent - Output Fluxgate
The current-output fluxgate may be tuned by using a serial capacitor. Such tuning increases the sensor sensitivity in the situation when the pick-up coil has a low number of turns. We achieved a signal/feedthrough ratio improvement by a factor of 5. The measured parameters fit the simplified theoretical model within 20% deviation
