Model 906 Little Dipper In-Place Inclinometer
Little Dipper is an in-place inclinometer system for monitoring slopes, embankments, deep excavations, tunnels, tank foundations, retaining walls and other types of ground movement. Installed as a string of vertical or horizontal sensors inside inclinometer casing, or by direct burial, this instrument provides a continuous record of ground displacement. Fiberglass rods connect the sensors inside the casing, and fins or universal pivots couple the sensors to the casing walls. Little Dipper’s on-board electronics accept a wide input voltage range and drive long cables without signal loss. The waterproof and non-corrodible ABS sensor housing also makes the Little Dipper a popular tool for underwater tilt measurements in shallow marine applications. Select analog voltage output (biaxial) or 4-20 mA output (uniaxial only).

Clinometer Pak 420
The Clinometer Pak 420 is the packaged version of our Tulip 4-20 mA clinometer. Its rugged aluminum enclosure provides mechanical and environmental protection for indoor or outdoor use. This uniaxial instrument is current loop powered, so measurements can be made over long cables using an economical 2-wire pair. It also measures temperature using a built-in thermistor. Use it to monitor the angular position of conveyers, booms, ramps and machinery; perform antenna tilt error corrections; and track the pitch and roll of ships, buoys, ROV’s and towfish.

Model MD 900-T Digital and Analog Clinometer
This economical biaxial clinometer has a wide variety of industrial, scientific and GPS uses. Many thousands are used today for antenna positioning, surface and subsea marine applications, structural monitoring, and industrial test and measurement. The clinometer is housed in an easily mountable enclosure and provides an RS232 serial interface and analog outputs via a 6-pin NEMA 4X connector. User-selectable firmware features include auto zero, sampling frequency, low-pass filtering and on-board data storage. Factory calibration values are stored in nonvolatile memory, and output data (X tilt, Y tilt, temperature, serial no.) are provided in several GPS-compatible formats. You can easily graph and log your measurements with our ZAGI user-interface software, included with every unit. Options include extended memory, real-time clock, RS422 output, viscous damping and submersible housings.

Pro 3600 Digital Protractor
This revolutionary, handheld measuring tool provides an immediate, digital reading of all angles in a 360º circle. As the protractor is moved, the liquid in the sensor seeks a new position, resulting in changes in the sensor’s electrical capacitance. A microprocessor analyzes the changes and calculates the angles seen on the display. The Pro 3600 also outputs its measurements in a continuous RS232 data stream that can be read by computers, data loggers and printers. Normally, level is displayed as 0.00º. However, a new reference point for 0.00º can easily be established by pushing the ALT ZERO button. You can also “freeze” any displayed angle by pushing the HOLD button. Display resolution is 0.01º near level (0.00º to 9.99º) and 0.1º at all other angles (10.0º to 90.0º). The bottom surface contains a V-groove and threaded mounting holes. The Pro 3600 is easily recalibrated by the user in just a few minutes without any special fixtures.

Model 901 and 902 Biaxial Clinometers
Specifications:
Model 901 (horizontal) and 902 (vertical) Biaxial Clinometers accurately measure angular position with the same performance as Model 900, but in a slim design for use in narrow spaces. These conveniently sized, low-cost units fit neatly into underwater pressure housings, well logging tools, drilling equipment and many other devices. The dual-axis (biaxial) Models 901 and 902 measure rotations about two orthogonal axes. Their high-level voltage outputs allow signals to be delivered over long cables.

Tulip 4-20mA Uniaxial Clinometer
Tulip 4-20mA Uniaxial Clinometers are compact and accurate uniaxial instruments for measuring angular position where space is limited. Dimensions are the same as Models 901 and 902. High-gain, standard and wide-angle versions are available, each with a different angular range. Tulip clinometers are current loop powered, so measurements can be made over long cable lengths using an economical 2-wire pair. Choose between vertical and horizontal versions. The horizontal version measures either longitudinal or transverse rotation to give you maximum flexibility when designing it into your system. As an added bonus, Tulip clinometers measure temperature using a built-in thermistor.

IRIS Tilt Switch Controller
IRIS combines a digital, dual-axis clinometer and a powerful control device in one compact unit. This remarkable instrument enables you to measure and respond to rotational movements in any direction with reference to the unchanging gravity vector. IRIS is an ideal choice for OEM applications, where it can be used to maintain platform levelness, avoid tip-over conditions, prevent out-of-range movement, and perform other control functions. IRIS has 5 user-programmable thresholds that control TTL-compatible CMOS outputs (0-5 VDC), with 3 additional control outputs available for custom applications. Biaxial tilt and temperature are provided in user-selectable RS232 or RS422 output protocols. A powerful selection of firmware commands puts you in charge of sampling frequency, output filtering and many other functions. The versatility of this small device will amaze you!
