The Jewell Instruments A900 Biaxial Tiltmeter is an inexpensive, gravity-referenced clinometer with analog voltage output and compact dimensions. Sold without a housing, its small size and performance make it an excellent choice for many OEM, test and measurement applications. It is available in high-gain, standard and wide-angle versions, each with a different angular range. The Model 900 accepts a wide input voltage range and provides high-level single-ended outputs that are easily measured with any voltmeter or digital recording system. Viscous damping and temperature measurement are available as options.

Applications include automation and robotics, drilling and mining machinery, construction equipment, ships, buoys, ROVs, towfish, aircraft, and antennae. Features: measures rotation in two orthogonal vertical planes, detailed 21 point calibrations supplied for each axis, no mechanical moving parts, liquid filled glass sensor, fiber glass PC board, operating temperature -40 to 85°C.
