Model 901 (horizontal) and 902 (vertical) Uniaxial & Biaxial Clinometers accurately measure an angular position with the same performance as Model 900, but in a slim design for use where space is limited. High-gain, standard, and wide-angle versions are available, each with a different angular range. A901 and A902 (biaxial) use high-level voltage outputs to allow signals to be delivered over long cables. C901 and C902 – also referred to as ‘Tulip’ (uniaxial) are loop-powered, so measurements can be made using an economical 2-wire pair. These conveniently sized, low-cost units fit neatly into underwater pressure housings, well logging tools, drilling equipment, and many other devices.
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).
