Crossbow Single- and Three-Axis Accelerometer Series Sets New Industry Price-Performance Points for Low-G Measurements.SAN JOSE San Jose, city, United States San Jose (sănəzā`, săn hōzā`), city (1990 pop. 782,248), seat of Santa Clara co., W central Calif.; founded 1777, inc. 1850. , Calif.--(BUSINESS WIRE)--May 3, 1999-- Crossbow Technology
Crossbow Technology, Inc. (also referred to as XBow) is a California-based company with two distinct product lines. One is based on MEMS inertial sensor systems. , Inc. today introduced its new LF Series of single- and three-axis accelerometers, providing high stability and low noise for inertial measurements, seismic vibration sensing, directional drilling Directional drilling (sometimes known as slant drilling outside the oil industry) is the science of drilling non-vertical wells. Directional drilling can be broken down into three main groups: Oilfield Directional Drilling, Utility Installation Directional Drilling (commonly , automotive testing, stabilization, precision tilt/sway, and orientation measurements. Crossbow's LF Series is the only device in its class that sells for under $500 per axis, with a $419 price for the three-axis solution. Competitive solutions often cost between $500 and $1,000 per axis. The CXL CXL Used on the consolidated tape to indicate that a transaction reported earlier has been canceled: CXL.5 SLS.BK.GY 49. 02LF3 accelerometer accelerometer Instrument that measures acceleration. Because it is difficult to measure acceleration directly, the device measures the force exerted by restraints placed on a reference mass to hold its position fixed in an accelerating body. also is the industry's first silicon micromachined, high-stability three-axis packaged solution. Other high-stability three-axis sensors must be built and aligned by the customer from three single-axis solutions. High Performance and Low Noise The LF Series single- and three-axis accelerometers are precision +/-1G and +/-2G acceleration sensors with DC-100Hz bandwidth. A noise floor of 100uG/RtHz delivers resolution on very small signals. Low bias drift makes the sensors outstanding for DC applications. The accelerometer is a combination of a capacitive sensing element coupled to a signal conditioning ASIC (Application Specific Integrated Circuit) Pronounced "a-sick." A chip that is custom designed for a specific application rather than a general-purpose chip such as a microprocessor. . The LF Series sensing element is a bulk micromachined three-layer silicon structure. The three layers form a differential capacitor with a low noise output. The sensor is bonded to a high-quality ceramic substrate where it is coupled to signal conditioning electronics. The entire package design is optimized for minimal thermal hysteresis hysteresis (hĭs'tərē`sĭs), phenomenon in which the response of a physical system to an external influence depends not only on the present magnitude of that influence but also on the previous history of the system. , yielding superior DC response. No External Components Required The LF Series operates on a single DC supply of 5V or an 8 - 30 Vdc unregulated supply with the -R option. The LF Series sensor provides a direct high-level analog voltage signal output. The output requires no external signal conditioning and is easy to interface to standard data acquisition systems. A standard A/D converter can be used to convert the analog output to digital for further processing. Full specifications and an application note are available at the company's web site at http://www.xbow.com/html/product.htm. Each module's offset and scale factor is factory calibrated cal·i·brate tr.v. cal·i·brat·ed, cal·i·brat·ing, cal·i·brates 1. To check, adjust, or determine by comparison with a standard (the graduations of a quantitative measuring instrument): and tested. Standard modules have a bandwidth of 125Hz. Various Package Configurations and Mounting Options The LF Series accelerometers are available in plastic (1.875"w x 0.75"h x 1"d) or aluminum (2"w x 0.86"h x 1.2"d) packaging or an aluminum Z-axis micro-package (0.8"w x 0.3"h x 0.6"d). The +/-1G family members include the CXL01LF1 X-axis sensor, the CXL01LF1Z Z-axis sensor, and the CXL01F3 three-axis sensor. The 2G family members include the CXL02LF1 X-axis sensor, the CXL02F1Z Z-axis sensor, and the CXL02F3 three-axis sensor. Pricing is $199 for the one-axis accelerometers and $419 for the three-axis accelerometers. All of the LF series products are available in production units now. These products can be ordered from the company's web site at http://www.xbow.com. Company Background Crossbow Technology, Inc. develops, manufactures, and markets a wide range of cost-effective acceleration, tilt, magnetic orientation, and inertial sensors and sensor-based analog and digital subsystems to OEM (Original Equipment Manufacturer) The rebranding of equipment and selling it. The term initially referred to the company that made the products (the "original" manufacturer), but eventually became widely used to refer to the organization that buys the products and customers in a variety of industries. Crossbow crossbow: see bow and arrow. crossbow Leading missile weapon of the Middle Ages, consisting of a short bow fixed transversely on a stock, with a groove to guide the missile and a trigger to release it. enhances its commitment to customers by working closely with them to customize its offerings to fit their specific needs. The company, founded in 1995, is located at 41 E. Daggett Drive, San Jose, CA 95134. Telephone: 408/965-3300. Fax: 408/324-4840. Email: info@xbow.com. Visit http://www.xbow.com. |
