Jewell digital compasses offer high performance in a compact package

One of the ECC-2D series of digital compasses

Durham Instruments carries test and measurement devices for Canadian businesses from various international producers. One of them is Jewell Instruments, which manufactures the ECC-2D series of digital compasses. Jewell works from more than 40 years of experience in providing precision, force-balanced accelerometers to offer electronic compass parts with a typically high attention to detail. Every digital compass in this line is an inexpensive, two-dimensional unit in a compact package, with low power consumption and high dependability – making it ideal for industrial applications.

Four wires for various functions

The ECC-2D series is perfect for several common tasks, including platform stabilization, satellite antenna control, ROV/UUV unmanned underwater vehicles, marine navigation surveying and mapping, weather buoys, and antenna positioning. Durham Instruments deems it suitable for use in the general manufacturing, aerospace, automation, forestry, military, mining, and transportation industries and for research and development.

Among the key features of each of these digital compasses:

• Heading accuracy of plus or minus one degree;
• Hard and soft iron magnetic compensation;
• An operating temperature range from -40 to 85 degrees Celsius;
• A 5Vdc power supply;
• An IP67 seal;
• Weight of 160 grams minus the cable;
• Dimensions of only 61 by 35 by 21 millimetres, which leaves a small footprint;
• RS-232, RS-485, and TTL outputs; and
• Four wires for different functions, coloured red, black, yellow, and green.

Technical specifications of the ECC-2D series include the following: heading resolution of 1/10 of a degree; pitch accuracy that ranges from one to three degrees; pitch title angle of plus or minus 80 degrees; roll accuracy from one to three degrees; roll tile angle of plus or minus 80 degrees; best compensation angular range of 40 degrees; both hard and soft iron calibration; magnetic field interface calibration method of plane rotation in a circle (i.e., two-dimensional calibration); startup delay of less than 50 milliseconds; maximum output rate of 20 hertz; baud rate from 2,400 to 19,200; binary output format; custom input voltage from nine to 36 Vdc; and input current of 45 mA (maximum operating), 35 mA (idle), or no more than 35 mA (standby).
