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.
The ECL low-power digital compass is designed specifically for commercial, industrial, and military users. The ECL series will be of particular interest to ROV and AUV manufacturers who are concerned with power usage and accurate heading in all types of challenging conditions. In standby mode, it draws a mere 50 microamps and requires only 15 mA in run mode. It provides accurate heading data in less than a tenth of a second from wake up. An extended range tilt sensor is available that allows for ±60° of pitch and roll.
The ECS digital compass represents the state-of-the-art in magnetic compassing. It combines a precision 3-axis solid-state magnetometer and a rugged 2-axis electrolytic tilt sensor to provide accurate heading and tilt measurements over a wide range of environmental conditions. The firmware and signal processing algorithms have been refined and improved over three prior generations of compasses to deliver the ultimate in performance from the available sensor data.
The ECV eCompass Series is a 3D electronic compass providing stable azimuth, pitch, and roll measurements in dynamic conditions. As an enhanced version of our ECG Series, the ECV includes a full suite of precision, 3-axis, MEMS sensors, and an optional dual-axis electrolytic tilt sensor, for the ultimate in near-level accuracy. A high-performance microcontroller orchestrates the fast measurement sequence, sensor calibration adjustments, frame-of-reference translations, trigonometric calculations, and advanced signal processing required to provide accurate heading, pitch, and roll outputs.
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.
The IRIS-SC digital signal conditioning card is a powerful control device designed for use with all Jewell miniature tilt sensors. Output is ASCII RS-232 or RS-422(485) serial. Standard firmware includes five user-programmable alarm/trigger thresholds for tilts tilt switch/control applications. When a selected threshold is reached, the circuitry sets the output high
on one of the pins in the H3 control connector. Other firmware features include user-programmable data output rates, sample averaging, autozero (nulling), and baud rate. The IRIS-SC can also log up to 22,000 samples to internal memory for data dump/download on user command.
All IRIS-SC units include calibration when ordered with Jewell miniature tilt sensors (specify calibrated range on order).
