These versatile, high-precision, biaxial tiltmeters are well suited for a wide variety of measurement

zTuff Tilt 420 4-20mA Precision Tiltmeter (Uniaxial) The Tuff Tilt 420 combines precision, long-term stability and rugged durability in a compact and reliable instrument. The internal sensing element is a gravity referenced ceramic tilt sensor that delivers high dynamic range and the best resolution of any sensor in its class. Housed in a weatherproof enclosure, this tiltmeter may be used outdoors and in other wet environments. The Tuff Tilt 420 is current loop powered, so tilt measurements can be made over long cable lengths using an economical 2-wire pair. As an added bonus, it also measures temperature using a built-in thermistor. Typical applications include: • Monitoring the performance of bridges, dams and other large structures; construction monitoring (standard version) • Antenna leveling and zenith finding (high-gain version) • Measuring the angular position of dam gates and Call us today for details about this versatile device! other machinery (wide-angle version).
