900 Series Tiltmeters and Clinometers

The Model 904-T Clinometer Pak
The Model 904-T Clinometer Pak unites our Model 900 Biaxial Clinometer with a weatherproof NEMA 4X (IP65) enclosure for indoor or outdoor applications that demand mechanical and environmental protection. Choose the high-gain, standard or wide-angle version, each with a different angular range. Clinometer Pak’s internal circuitry accepts a wide input voltage range and provides stable, low-impedance analog outputs for measurement by dataloggers, PLC’s, digital voltmeters and other recording devices. A temperature sensor is included as a standard feature. Options include viscous damping and 0-5 Volt output. This product is also available in a submersible stainless steel enclosure.

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.
 
Specifications:
Range ±10°/±25°/±50°
Resolution 0.005°/0.01°/0.02°
Output 4-20 mA (2-wire current loop)
Power Requirement ~12 to 29 VDC
Temperature Range -40 to +85°C
Dimensions 120 x 80 x 60 mm
Housing Painted, die cast aluminum, NEMA 4X (IP65)

 

 
 
 
 
 
 
 
 
 
 
Model MD 900-T Digital & 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.
 
Specifications:
Range 360°
Resolution 0.01º near level (0.00º to 9.99º), 0.1º above 10.0º
Output ASCII, RS232, 9600 baud, continuous on request
Power Requirement 9-Volt battery or external
Temperature Range -5 to +50°C operating

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).
 
Specifications:
Range ±12°/±30°
Resolution 0.005°/0.01°
