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 for the A900 Biaxial Tiltmeter include:

  • Automation and robotics
  • Drilling and mining machinery
  • Construction equipment
  • Ships, buoys, ROVs, towfish
  • Aircraft
  • Antennae
