Jewell Instruments A802 Specifications

Model A802 DeepWater Analog Tiltmeter

Pin

The model A802 Deepwater is a high-precision
submersible tiltmeter for use in marine,
offshore, and deep ocean applications. Using an
absolute gravity referenced electrolytic sensor,
the A802 delivers superior measurement
accuracy with virtually no long-term drift. High­gain 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 data recorder. All units are rated to
+2500m waterproof for advanced protection
from the elements. Use the A802 “Deepwater”
for structural monitoring, angle measurement
and control, platform leveling, and more.
