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.

Getting down to earth

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.

Rate/RPM/Frequency Input DPM

Tucson, Ariz. —Model 210 digital panel meter accepts input signals from magnetic pick-ups, photocells, encoders, proximity detectors, transmitters, and power lines. Its Frequency-Voltage technique converts these inputs to a 0-2 V dc for the 4.5 digit A/D. The F-V system allows frequency measurement and control without the need for specific gear ratios.

Ultrasonic Proximity Sensors

Newton, Pa. —SonicLaser ultrasonic proximity sensors come in 18 models and feature a narrow, concentrated beam angle 2.5° off-center axis. This narrow beam angle is said to render the sensor insensitive to echo interference from surrounding objects. Measuring ranges vary from 3.28 to 26.25 ft.
