800 Series Tiltmeters and Clinometers
|
Model 801 Tuff Tilt 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. Specifications:

Tuff Tilt Digital
This product is the digital member of our Tuff Tilt family. Use it for test and measurement work requiring serial data communications, high precision, compact size, and robustness. Among its standard features are 16-bit A/D resolution, onboard data logging, a real-time clock, and measurement of temperature. User-selectable firmware commands include autozero, sampling frequency, low-pass filtering, and output data format. Several output formats are supported, including those compatible with popular GPS receivers. You can combine the Tuff Tilt Digital with GPS for simultaneous measurement of displacement and tilt. We also offer wireless connectivity and tilt alarm capability for these devices. ZAGI graphical user-interface software is provided with each tiltmeter. Specifications:

Model 802 DeepWater Submersible Tiltmeter
The Model 802 DeepWater is the fully submersible cousin of our Model 801 Tuff Tilt. Performance features are the same, but the DeepWater housing is machined from a solid piece of 316 stainless steel and incorporates a high-pressure neoprene connector. Pressure rating is 250 bars (2500 meters depth). Higher-pressure versions may be special ordered. Temperature rating is governed by the neoprene connector. Wider temperature range is available with other connector types. DeepWater tiltmeters are excellent choices for monitoring dams, oil platforms, pipelines and underwater machinery. Specifications:

DeepWater 420
DeepWater 420 is the submersible equivalent of our Tuff Tilt 420. It has 4-20 mA output and is current loop powered, so that tilt measurements can be made using a 2-wire pair. The massive housing is machined from a solid piece of 316 stainless steel and is rated to 250 bars pressure (2500 meters depth). Higher-pressure versions may be special ordered. The temperature rating is governed by the neoprene connector. Wider temperature range is available with other connector types. Use DeepWater 420 in the same places you would use Model 802, but where 4-20 mA output is required. Specifications:

DeepWater Digital
DeepWater Digital is the submersible version of our Tuff Tilt Digital tiltmeter. Performance and firmware are the same, but the 316 stainless steel housing is rated for submergence to 250 bars pressure (2500 meters depth). The neoprene connector is wet-mateable. DeepWater tiltmeters are excellent choices for offshore work and other underwater applications. Specifications:

Model 800P Portable Tiltmeter
The Model 800P Portable Tiltmeter is a versatile and accurate hand-held instrument for monitoring structural and foundation movement. Measurements are taken from tilt plates that have been cemented or bolted to any horizontal or vertical surface. Indexing bars on the bottom and sides of the tiltmeter enable you to reposition it on the tilt plate exactly, every time. Surveys are economical because only one tiltmeter is needed to make measurements at an unlimited number of points. When continuous monitoring is not required, Model 800P is an excellent choice. The Portable Tiltmeter System includes one tiltmeter, one power and display unit, and a tough plastic carrying case. Ceramic or Aluminum Tilt plates are purchased separately. Specifications:

Beamer Tilt Beam Sensor
The Beamer beam sensor detects rotation (tilt) between its two fixed end points. Because the beam length is known, changes in tilt are easily converted to displacements using simple trigonometry. Beamers span cracks and local discontinuities to measure the overall movement of walls, tunnels and other structures. They can be connected end-to-end to determine cumulative displacement along a horizontal or vertical profile. They are available in vertical or horizontal configurations, and in 1, 2 and 3m lengths. A precision ceramic tilt sensor and signal conditioning electronics are mounted inside the rigid aluminum beam. Sensor null can be manually adjusted over a ±5 degree range. Choose analog voltage or 4-20mA output. Mounting hardware (part no. 89028) is sold separately. Specifications:

Beamer LT
The Beamer LT is a low-cost beam sensor that uses a Model 901 Clinometer for tilt measurement and signal conditioning. It is operated the same way as the standard Beamer. Measurement range is fixed at ±5 degrees, which allows for easy installation. This is a practical tool for measurements in tunnels and other areas of constant temperature. The Beamer LT is available in vertical or horizontal configurations; 1, 2 and 3m lengths; and with analog voltage or 4-20mA output. Mounting hardware (part no. 89028) is sold separately.
