Ready-to-use instruments utilise fluxgate technology
For the first time, Fluxgate World is introducing complete, ready-to-use, PC-based instruments in addition to its established range of sensors for OEM integration. A high-sensitivity magnetometer with a 100pT resolution is claimed to offer an unrivalled price/performance ratio, and a precision inclinometer achieves 0.2arcsec resolution over a +/-5degree range.
Both instruments result from Fluxgate World's innovative programme of development, together with application of the core fluxgate technology for which the company is becoming increasingly well known.
The A6320 precision three-channel magnetometer accepts different fluxgate sensing heads and each channel can operate in direct or differential mode. Heads currently available include a single fluxgate for direct measurement of magnetic field strength, and a twin, 2m-separation head for differential measurement. Custom software is provided for the display of readings on a standard PC. Direct-mode operation allows field measurements to be made for a broad range of scientific and engineering applications such as checking for flux leakage, stray flux and residual fields. The differential mode allows background fields to be cancelled out and the gain increased to detect very small anomalies in the field. This is of particular use in geophysical surveying and as a method of detecting the presence of objects that disrupt the background magnetic field. Sensor heads are available to measure fields up to 16mT. The photo shows an A3111 magnetometer single-channel sensor head.
