Miniature Fluxgate Magnetometer WFG-110

Product catalog summary

Overview: The document provides detailed specifications and applications for the Model WFG-110, a 3-axis Fluxgate Magnetometer designed for measuring magnetic fields less than 1 Gauss. It is compact, rugged, and operates with low noise levels.

Specifications: The magnetometer features a noise level of less than 3x10^-6 G RMS/Hz^½, a frequency response from DC to 400 Hz, and a linearity of ±0.1% of full scale. It has a zero output temperature coefficient of less than ±5x10^-5 G/°C and a scale factor temperature coefficient of less than ±0.02% full scale/°C. The sensitivity is ±4 V/G, with orthogonality and alignment accuracy of ±2°.

Dimensions and Power: The device is cylindrical, measuring 0.725 inches in diameter and 1.5 inches in length, weighing 18 grams. It requires a power input of +5 VDC at 30 mA and -5 VDC at 30 mA.

Applications: The WFG-110 is suitable for OEM and system integration, fluxgate compass systems, magnetic signature measurement, magnetic fuses, and measuring magnetic fields generated by power lines.

Features: The system provides analog output voltages proportional to the magnetic field in three orthogonal directions, with a full-scale output of ±4.0 volts representing a magnetic field of ±1.00 Gauss. It offers direction accuracy better than 0.1° and can be combined with a precision 3-axis accelerometer for accurate roll, pitch, and yaw angles.

Additional Options: A calibration sheet can be provided with each unit, detailing zeros, scale factors, and orthogonality constants for each axis to enhance system accuracy.

Connection Details: The system connects via six #26 gauge Teflon insulated wires, each 6 inches long, with specific wire color designations for input and output functions.

The system operates from input voltages of ±5 VDC and consumes a total power of 300 mW. The Fluxgate Magnetometer system provides 3 analog output voltages proportional to the magnetic field in three orthogonal directions. Full scale output is ±4.0 volts; this voltage represents a magnetic field of ±1.00 Gauss (ask on ±2 and ±10 Gauss). Output scale factor is adjusted to an accuracy of ±0.2%. The system noise level is <3x10-6GRMS/Hz½. As a magnetic compass, the Fluxgate Magnetometer Model WFG-110 can provide direction accuracy to better than 0.1°. Some applications combine the Fluxgate Model WFG-110 with a precision 3 axis accelerometer to provide roll, pitch and yaw angles accurate to 0.1°. In magnetic anomaly detection situations, the low noise level of the Model WFG-110 enables very small magnetic signatures to be measured. This enables a large distance spacing between the Model WFG-110 and the anomaly being measured. Range is propor- tional to the quotient of these quantities. As an option, a calibration sheet can be provided with each unit giving data on zeros, scale factors and orthogonality onstants for each axis. This data enables external correction of the output voltages to increase overall system accuracy. Connection to the system is accomplished by means of six #26 gauge Teflon insulated wires with a nominal length of 6".
