Geophysical/Tech Tilt Sensors

Jewell Instruments divides its Geophysical/Tech tiltmeters into six different series based on model numbers. Some of the resolutions are reported in microradians or even nanoradians, reflecting the extremely high sensitivity of some of these instruments.

Electrolytic Tiltmeters


All Jewell Instruments Geophysical/Tech tiltmeters and clinometers include full signal conditioning electronics that produce stable output signals over a wide range of input voltages. This important feature means you can be confident that your measurements represent actual movement, not power supply variations. The high-level voltage, current and serial outputs provided by our electronics are reliably delivered over long cables and wireless data links.

High Precision Tiltmeters for Advanced Research






Miniature Tilt Sensors & Signal Conditioners




Our Digital Inclinometer System is the most advanced traversing inclinometer on the market. Use it to measure lateral displacement of inclinometer casings in boreholes in soil and rock. Monitor movement of landslides, embankments, excavations, retaining walls, roadways, dams and tunnels. The system combines an iPAC Pocket PC as the readout unit, a waterproof stainless steel probe and a low-stretch graduated cable. Inclinometer System

Dynamic Concrete and Dynamic Asphalt Strain Gages measure axial strain under high frequency (dynamic) conditions. Using four active elements of a Wheatstone bridge circuit, these gages compensate for temperature, rejects bending strain and compensates for lead resistance.
