Uniaxial Tiltmeter

PRECISION & DURABILITY

ELECTROLYTIC TILT TRANSDUCER

RUGGED WEATHERPROOF ENCLOSURE

The TUFF TILT 801 uniaxial tiltmeter  combines precision and durability in an economical instrument for a wide variety of monitoring and measurement applications

Description

The TUFF TILT 801 is an economical uniaxial tiltmeter for a wide variety of monitoring and measurement applica tions. It incorporates a gravity-referenced electrolytic tilt transducer as the internal sensing element, offering unrivaled precision and long-term stability. Housed in a rugged NEMA 4X enclosure, this analog output tilt meter may be used outdoors and in other wet or harsh environments, although the unit is not submersible.

The TUFF TILT Uniaxial Tiltmeter is ideal for structural load testing, monitoring of walls and foundation movement, surveillance of natural and manmade structures (bridges, dams, etc.) and machine positioning and control.
