Tuff Tilt is a precise and rugged uniaxial tiltmeter suitable for many different applications. This workhorse is widely used for structural monitoring and for industrial test and measurement. Housed in a rugged weatherproof enclosure, this analog output tiltmeter may be installed outdoors and in other wet environments. Typical applications include construction monitoring, monitoring of bridges and other large structures, antenna leveling, and rotary position sensing for dam gates and other machinery. Tuff Tilt tiltmeters incorporate a ceramic tilt sensor that delivers low thermal sensitivity, high long-term stability and the best resolution of any sensor in its class. Model 801 includes a temperature sensor.
