Rosemont, IL (Chicago suburb) —Control equipment and devices need to upgrade their built-in toughness to be able to keep pace with the harsh application environments they serve. A case in point is the increasing ruggedness exhibited by feedback devices. Among products displayed by Heidenhain Corp. at National Manufacturing Week (NMW) shows, March 21-23, was an explosion-proof version of its rotary encoder—ROD 420—which embodies a standard 58-mm (2.28 in.) diameter housing, compact total length of 83 mm, and line counts from 250 to 5,000.
Stationary/rotating switches and associated electronics installed outside the main motor housing offer protection from heat and dirt and permit easy replacement. Rotor coil leads brought out through the bearing via slots in the motor shaft help implement the design. It may look like an ordinary ac or dc motor and consist of familiar mechanical parts, but that’s where similarities end for DynaMotor —a variable-speed brushless motor-drive package from DynaMotors Inc.— which applies optically controlled solid-state switches (transistors) embedded in its rotor windings to control current, hence torque.

Today's extreme mountain-bike riders subject suspension forks to high stress forces. After miles of ascents and descents on some of the world's toughest terrain, the forks have a tendency to fatigue. If failure occurs, it's typically on the critical weld between the top of the fork and the stem that fits into the frame headset.
By automatically shifting the 1-million pixel target area, the camera can use the full 2-million pixel image to perform inspections, widening range and increasing speed, says Keyence of its CV-2100/2600 line. (2600 is shown.) Keyence 's CV-2100/2600 machine vision cameras claim a number of industry firsts, including high-speed enhancement with 1 and 2 mega-pixel modes and highly sensitive image capturing, with an 81-level span/shift function. The 1 mega-pixel mode cuts an area of 1-million pixels from the 2-million-pixel CCD, improving speed and accuracy for better support of high-speed production line applications, Keyence says. Higher resolution with same field of view is said to augment measurement accuracy; wider range with same precision per pixel can avoid necessity of mounting multiple cameras.

Emerson Process Management introduced a triaxial accelerometer with integral magnet that is smaller than conventional triaxial accelerometers, delivers excellent measurement quality, and speeds data collection in the field by technicians using the dual-channel CSI 2130 Machinery Health Analyzer, the company says. Emerson’s new triaxial accelerometer decreases implementation costs because it does not require a stud mount for monitoring rotating equipment. Instead, it can be magnetically attached on a mounting pad and deliver measurements up to 10 kHz in the primary axis and above 3 kHz in the secondary axes. When used with Emerson’s PeakVue technology, the sensor’s high frequency response range identifies bearing faults and improper machine lubrication, ensuring users are made aware of these potentially damaging conditions, the company suggests.

July 8, 2005 Highlights Sponsored byControl Engineering This review of the advantages and disadvantages of string potentiometers and string encoders, also known as cable position transducers (CPT), will help you better understand the strengths and weaknesses of CPT technology for determining the optimal displacement measurement solution for your application. Cable Position Transducers for Control and Monitoring Cable position transducers (CPTs), or string potentiometers/encoders, were first developed in the mid-1960s in concert with the growth of the aerospace and aircraft industries. The first applications involved the monitoring of aircraft flight control mechanisms during flight testing. While the technology is now proven and mature, it is certainly not dated. A range of high-performance and cost-conscious applications use CPTs as the basis for key control and monitoring operations, such as: Delta IV missile thrust vectoring system; Military fighter level sensor; Diesel engine fuel index measurement; International Space Station environmental control systems; Commercial and military aircraft flight data recorder input sensors; Medical table actuation feedback system; and Logistics sorting and positioning equipment. The technology is so widely used that it is referred to by a variety of names, such as: cable-actuated position sensor, cable extension transducer, cable sensor, cable-actuated sensor, CET, CPT, draw wire encoder/transducer, wire rope transducer, wire sensor, wire-actuated transducer, and yo-yo potentiometer. These names all refer to devices that measure displacement via a flexible displacement cable that extracts from and retracts to a spring-loaded drum.

W hen a personal computer locks up for no apparent reason, or a load cell stops updating for a short period the tendency is to mumble some harsh words and do what's necessary to restore operation of the faulty device. Often the cause of the interruption goes undetected and people begin to accept such occurrences as 'just the way it is;' but more times than anyone knows the root cause of intermittent interruptions is caused by a poor grounding system. Grounding and bonding of electrical systems is mainly used to control dangerous overvoltages and is very important for personnel safety. However, increased use of commercially available microprocessor-based products and the urgency to get them operational as quickly as possible increase opportunities to introduce 'dirty grounds' into the business and manufacturing environment.
