ECV-IMU Inertial Measurement Unit
Jewell Instruments’ offers ECV-IMU Series initial measurement units which assure high accuracy in a small package. This inertial measurement unit is a cost efficient, low power consuming device which provides stable azimuth, pitch, and roll measurements in dynamic conditions. This sensor consists of 3-axis angular rate gyros, 3-axis accelerometer, 3-axis magnetometer, and optional 2-axis electrolytic tilt sensor. These IMUs have a wide operating range and are factory calibrated. Hence, they offer an accurate and fast output through RS-485.

ECG eCompass Series
If your compass application involves vibration, acceleration, uneven terrain, or rough seas, the ECG Series, a gyro-stabilized electronic compass, is an uncompromising solution that will outperform rival units that cost more. The ECG provides remarkably accurate heading, pitch, and roll in dynamic conditions. It all starts with a precision 3-axis solid-state magnetometer. Two angular rate gyros independently stabilize pitch and roll. They augment a dual-axis, electrolytic tilt sensor that provides precise tilt measurements in static environments. Two sets of independent filters, one set for pitch and one for roll, combine gyro and electrolytic sensor measurements to provide the best available tilt measurements.
