GENERAL DESCRIPTION

Honeywell’s three-axis strapdown magnetometer detects

the strength and direction of the earth’s magnetic field and

communicates the x, y, and z component directly via serial

bus. TheHMR2300riscompliantwithapplicableMIL-STD-

810E requirements for military and commercial flight sys-

tems (see Table 6). It was designed to be a replacement for

bulky fluxvalve magnetic sensors commonly used in avia-

tion systems.

A unique switching technique is applied to the solid-state

magnetic sensors to eliminate the effects of past magnetic

history. This technique cancels out the bridge offset as well

as any offset introduced by the electronics. The data is

seriallyoutputateither9,600or19,200baud,usingtheRS-

422 or RS-485 standard. The RS-485 standard allows

connection of up to 32 devices on a single wire pair up to

4,000 feet in length. An HMR address can be stored in the

on-board EEPROM to assign one of thirty-two unique ID

codes to allow direct line access. An internal microcontrol-

ler handles the magnetic sensing, digital filtering, and all

output communications eliminating the need for external

trims and adjustments. Standard RS-422 or RS-485 driv-

ers provide compliant electrical signalling.

The HMR2300r strapdown magnetometer provides an

excellent replacement of conventional fluxvalve sensors,

commonly used in aviation systems today. The HMR2300r

offers higher reliability (MTBF >50,000 hours) that reduces

maintenanceandrepaircost.Sincethedesignisstrapdown,

as opposed to a gimballed fluxvalve, it has no moving parts

to damage or wear out during severe flight conditions. Low

cost, highsensitivity, fastresponse, smallsize, andreliabil-

ity are advantages over mechanical or other magnetom-

eter alternatives. With an extremely low magnetic field

sensitivity and a user configurable command set, these

sensorssolveavarietyofproblemsincustomapplications.

A command set is provided (see Table 4) to configure the

data sample rate, output format, averaging and zero offset.

An on-board EEPROM stores any configuration changes

for next time power-up. In addition, the user has 55 bytes

of EEPROM locations available for data storage. Other

commands perform utility functions like baud rate, device

ID and serial number. Also included in the HMR magne-

tometer is a digital filter with 50/60 Hz rejection to reduce

ambient magnetic interference.
