Inertial introduces solid-state magnetometers

Inertial Aerosystems is offering the HMR 2300 and HMR2300r, two inexpensive and reliable microprocessor-based magnetometers from Honeywell.

The two devices consist of a three-axis smart digital magnetometer and a three-axis strapdown magnetometer suitable for flight systems.

Both products use the Honeywell HMC2003 hybrid analogue magnetometer to detect the strength and direction of the Earth's magnetic field and communicate the x, y and z components directly to a computer/serial bus (RS232/485).

They have a full-scale range of +/- 2 Gauss, less than 70 Gauss (0.02 of heading) resolution and accuracy of less than 0.5 per cent FS over +/- 1 Gauss.

With extremely low magnetic-field sensitivity and a user-configurable command set, storeable in an on-board Eeprom, these sensors solve a variety of problems in custom applications.

The HMR2300 has three independent bridges that are orientated to sense the x, y and z axis of a magnetic field.

The bridge outputs are then converted to a 16-bit digital value using an internal delta sigma A/D convertor.

The magnetometer is available standalone or in a non-magnetic alloy enclosure.

The HMR2300r strapdown magnetometer has no moving parts and offers higher reliability (MTBF of more than 50000 hours) than bulky, gimballed fluxvalve sensors.

The HMR2300r complies with the applicable MIL-STD-810 requirements for military and commercial flight systems.

It is slaveable to AHRS systems.

These products are suitable for use where space and weight are at a premium and have applications in navigation systems, laboratory, oil and gas exploration, remote vehicle monitoring, GPS backup systems, anomaly detection, traffic and vehicle detection and process control.
