The high-precision sensors in our 500- and 700-Series Tiltmeters are available as standalone modules for applications with size or weight constraints. Small and light, 755- and 756- sensors mount directly to critical system components, and are ideal for precision measurement and control applications where space is limited. Units are also are available non-outgassing (- VAC) versions for specialized vacuum applications. Standard biaxial modules also include a LMC35Z temperature sensor (not available for –VAC versions).

For peak performance, use your Miniature Tilt Sensors with Jewell’s precision signal conditioning electronics. All Miniature Tilt Sensors include calibration when ordered with Jewell electronics.
