The Jewell Instruments A801 Tuff Tilt Inclinometer combines precision and durability in an economical instrument. It incorporates a gravity referenced electrolytic tilt transducer as the internal sensing element, delivering high dynamic range and long-term stability. Housed in a rugged weatherproof enclosure, this analog output tiltmeter may be used outdoors and in other wet environments.

Applications include antenna leveling and tracking (Model 801-H), monitoring of bridges and structures (Model 801-S), and rotary position of dam gates and other machinery (Model 801-W). Features: ranges ±0.5°, ±3°, ±50°; resolution 0.0001°, 0.0006°, 0.01°; ±5 VDC single-ended and ±10 VDC differential outputs; low thermal sensitivity; high long-term stability; operating temperature -25 to 70°C.
