MFAM Module

Description

Geometrics has recently announced a revolutionary new line of magnetometer products based on recent research in miniaturizing atomic clocks and magnetometers. Advances by Geometrics allow for a 10-fold reduction in size and power consumption without sacrificing performance. New devices soon to be on the market are only about 15cc in size, and require only 2W per sensor. Manufacturing technologies for an additional 10-fold reduction in size and power consumption are available now. Recent advances in laser technology and MEMS fabrication techniques, supported by the Defense Advanced Research Projects Agency (DARPA) and the Strategic Environmental Research and Development Program (SERDP) , have led to miniaturized components for atomic clocks and magnetometers. Using its long experience in building field-rugged magnetometers, Geometrics has recently achieved the breakthroughs necessary in sensor and electronics design to bring cost-effective, reliable products to market. This advancement in sensing technology will make an enormous impact on sensing and detection applications. Many applications could benefit from lower cost, lower power sensors. Some applications will use a relatively small number of sensors, and others will create demand for a huge number of sensors. These applications and the required production technology must be carefully choreographed for the successful launching of this technology. We recognize that each customer has unique needs, so in order to better meet those needs we have created four different sensors, each with different technical specifications. These sensors are the Low-Noise MFAM, Low-Heading Error MFAM, Super-MFAM (combining the low-noise and low heading error configurations into the same MFAM Module) and the SX-MFAM for export compliance. To see the specifications of each, please refer to the "Spec Sheet" available for download below.

 

Features and benefits

MFAM Module

• Dual-Sensor Module: Two sensors allow for individual or gradient measurements. Reconfigure sensors to achieve dead-zone free operation anywhere in the world. Also allows for heading error compensation
• Small Size: No significant weight increase when added to existing instruments or systems.
• Low Power Operation: Decrease downtime by operating longer on a smaller battery.
• Modular Architecture: Integrate the MFAM module into your existing instruments and expand your service line.
• High Performance: Fast sampling and low noise allow for use in a variety of applications, including geophysics, non-destructive evaluation, magnetocardiography, and structural health fields.
