Catalog excerpts

Selection: The selection of the proper sensor depends on the range of the angle being measured and the sensitivity required. If the measurement is to find a precise gravity reference for leveling sensitive instruments or equipment, a single axis horizontal vial (banana) type level would be used. These types of levels have sensitivities of less than an arc second with a range of a few degrees. For larger angle measurements, a vertical pool type level would be used. These types of levels can have a range of up to plus/minus 90 degrees or greater. They are available in single or dual axis....

FIGURE #3 Electrical equivalent. Operating parameters: Electrolytic tilt sensors must be operated in the AC mode. Any direct current (DC) will cause the level to become unstable and even inoperable. The amount of current through the level must not exceed the maximum. Currents that are above the typical recommended value will cause the level to self heat and the readings will drift. The impedance value of the level must be specified to match the type of circuit used in order to limit the current. Excitation: The electrolytic tilt sensor (level) can be energized in a number of ways depending...
