Description:

The function of an electrolytic tilt sensor is to measure an angle or a null, or level, position with reference to gravity. The angle may be expressed in any one of the following; degrees, arc minutes (1/60^th of a degree), or arc seconds (1/60^th of an arc minute). These angles are generally referenced to a perpendicular line to gravity called a null or zero point. The amount of tilt from this point can be expressed as either positive or negative angle.

A single axis sensor would only measure an angle in one direction. To measure an angle in all directions, for example, to a compass heading, a dual axis sensor or two single axis sensors mounted 90 degrees to each other would be required. This would allow the measurement to be made in any direction by combining the readings of both axes (see figure #1). The Fredericks Company manufactures all of these types of levels.
