Tilt Sensors & Inclinometers
ECL – eCompass Series
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.
FEATURES:
- Wide Operating Temperature Range
- Single-Supply Operation
- Low Power
- RS-232 & TTL Outputs Available
- In-System Configuration & Test
- Plastic or Aluminum Enclosure Options
APPLICATIONS:
- Unmanned Vehicles
- Robotics
- Weather Buoys
- Antenna Positioning
- Marine Navigation
