About the 755 & 756 Miniature Tilt Sensors

– compact, high-precision tilt sensors for limited installation space

The 755 and 756 Series from Jewell Instruments are miniaturized tilt sensor modules (single- or dual-axis) that combine electrolytic tilt transducers in a rugged stainless-steel or aluminum housing. They are designed for applications with space or weight constraints—without compromising precision—using the same high-accuracy sensing elements found in the 500 and 700 Series tiltmeters.

Two variants to match your measurement task

755 Series (High-Gain): for very small tilt angles with high amplification
756 Series (Mid-Range): for larger tilt ranges and more general-purpose applications

Key benefits at a glance

Extremely compact & lightweight – ideal for direct mounting where space is tight
Single- or dual-axis (model dependent) for precise 1D/2D tilt measurement
Flexible mounting: drilled holes for vertical or horizontal installation
Vacuum-compatible versions (low outgassing) available for high-vacuum environments
Remote operation possible: sensors can be operated up to 100 m from the signal conditioner via cable

Typical applications

These compact modules are commonly used for precision alignment and positioning, for example:

X-ray mirrors
Telescope mounts
Wind tunnel models
Medical technology

The 755/756 Miniature Tilt Sensors are the right choice when you need high-precision tilt measurement in a very compact form factor—optionally vacuum-compatible—and want flexible single- or dual-axis integration into your measurement or control system.
