755 & 756 Miniature Tilt Sensors

755- and 756-Series Miniature Tilt Sensors contain one or two of our electrolytic tilt transducers in a solid stainless steel or aluminum housing, with holes for vertical or horizontal mounting. These are the same high-precision sensors that we use in our 500– and 700-Series tiltmeters. Several of the models are available in vacuum-compatible versions designed for minimal outgassing under high-vacuum conditions. Two options are available, the high-gain 755-Series and mid-range 756-Series. Typical applications for these compact modules include X-ray mirrors, telescope mounts, wind tunnel models, and medical devices. The sensors may be operated at a distance (cable length) up to 100m from their Jewell Instruments signal conditioner.
