Jewell Instruments A801 Specifications

Model A801 “Tuff Tilt” Analog Tiltmeter

The model 801 “Tuff Tilt” Analog Tiltmeter
combines high precision and durability in an
economical instrument package. Using an
absolute gravity referenced electrolytic sensor,
the A801 delivers superior measurement
accuracy with virtually no long-term drift, and
high-gain units are sensitive to <0.0017 mm/m
or better. Output is a stable ±5 DC voltage (±10
VDC differential), which can be read with any
VDC input datalogger. All units are rated IP65
waterproof for advanced protection from the
elements. Use the A801 “Tuff Tilt” for structural
monitoring, angle measurement and control,
platform leveling, and more.
