ECS eCompass Series
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.

Emico Series 802
Series 802 are very small, low-cost, uncalibrated devices for indicating on-off conditions or voltage transition points. They are rugged, dependable, and require less than 2mW to move the flag or pointer. The two types are:
Flag Type (802F)Â – A white flag moves from one end of the red & white scale to the other when a predetermined voltage value is exceeded. Provides on-off indication.
Pointer Type (802P) – A pointer moves across the scale to indicate circuit condition. The pointer may be factory set for left, right, or exact center position to indicate zero current. The center point can be specified for a given voltage (±5%) within the range of the device.
Either type can be made to operate with a Zener diode to indicate voltage changes as low as 1 volt.
