84053 & 59577 Mid-Range Ceramic Sensor Assembly
The Model 84053 Mid-range Ceramic Tilt Sensor is a compact and robust electrolytic tilt sensor with up to 1.75 µradian resolution. This precision sensor has a fast warm-up, high sensitivity, high repeatability, and excellent long-term stability. It is mounted on an anodized aluminum bracket that strengthens the assembly and simplifies the installation and repositioning of this versatile product. (Model 59577 is the same sensor without a mounting bracket). All 84053 and 59577 Ceramic Tilt Sensors include calibration over ±3° when ordered with Jewell electronics (or specify special/custom calibrated ranges on order). Use the 84053/59577 sensor for precision OEM applications where small size and peak performance are key such as leveling and positioning in a variety of test and measurement applications.
Model 701 Platform Tiltmeter Series
The Model 701-2 Platform mount tiltmeter is our most popular design for high precision tilt measurements. Units come with built-in invar leveling legs, for easy installation on any horizontal surface. The A701-2 also includes two switchable gains and two low-pass filter settings. Using an absolute gravity-referenced electrolytic sensor, the A701 delivers ultra-high sensitivity to <0.1 µrad with virtually zero long-term drift. The output is a stable ±8 DC voltage (±16 VDC differential). The D701 digital version has onboard memory, with a storage capacity of up to 22,000 samples.
Model 900 Biaxial Clinometer
The dual-axis Model 900 is an inexpensive, gravity-referenced clinometer with analog voltage output and compact dimensions. Sold without a housing, its small size and performance make it an excellent choice for many OEM, test, and measurement applications. It is available in high-gain, standard, and wide-angle versions, each with a different angular range. Model 900 accepts a wide input voltage range and provides high-level single-ended outputs that are easily measured with any voltmeter or digital recording system. Viscous damping and temperature measurement are available as options.
Model 901 & 902 Clinometer
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.
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).
Model MD908 ‘IRIS’ Tilt Switch
The IRIS Tilt Switch and Controller is a powerful tilt controller device that combines a digital, dual-axis clinometer and advanced firmware features in one compact unit. This remarkable instrument enables you to measure and respond to rotational movements in any direction concerning the unchanging gravity vector. Units ship standard with a 24-inch hook-up cable. 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.
Models 84064-02 & 59579-02 Wide-Angle Ceramic Sensors
The Model 84064-02 Wide-angle Ceramic Tilt Sensor is a high-precision electrolytic tilt sensor with terrific linearity over a full ±75° of angular range. The alumina sensor has a fast warm-up and excellent thermal, mechanical, and long-term stability. It is mounted on an anodized aluminum bracket for strength and easy installation (Model 59579-02 is the same sensor without the mounting bracket). The small and lightweight assembly attaches directly to the elements you want to measure, without unbalancing them or altering their performance. Use the 84064-02 and 59579-02 sensor for wide-angle sensor applications where high performance and linearity over range are key. Use any of our analog or digital signal conditioning units for operating these sensors.
All 84064-02 and 59579-02 Ceramic Tilt Sensors include calibration over ±50° when ordered with Jewell electronics (or specify special/custom calibrated ranges on order).
