This technical article from Linear Technology presents analogue-to-digital conversion circuits that directly digitise low-level transducer outputs, without DC pre-amplification. It also covers circuits that operate with thermocouples, strain gauges, humidity sensors, level transducers and other sensors.
Apart from its originally intended purpose for strain measurement, the metallic resistance strain gauge is extremely commonplace in transducer applications. Its low cost, high accuracy and ease of application make it an ideal transduction element and it is widely used in pressure, load, force, torque and displacement transducers. However, this article in Sherborne Sensors’ ‘Mike Might Know’ series focuses on semiconductor strain sensors.
There have been several breaches of security at high-profile institutions in recent times, and almost every day brings a new story of how a building has been compromised and critical data or hardware destroyed or stolen. Data centre operators have long understood the need for physical access control on server cabinets. There are many ways of securing data centres, and many solutions have evolved over time to address access control at doors and server cabinets.
Proper PCB layout at the early stage of a switching supply design is critical. Its importance cannot be overstated.
According to Linear Technology’s Jim Williams and Guy Hoover, the ability to faithfully digitise a sine wave is a sensitive test of high-resolution A?D converter fidelity. This test requires a sine-wave generator with residual distortion products approaching one part-per-million. Additionally, a computer-based A?D output monitor is necessary to read and display converter output spectral components.
This article from Fullbrook Systems describes how photometry and the use of fibre-optic technology can be applied to the scale-up and continuous flow technology in the specialist fine chemicals industry. This discussion focuses on mature and commercially available technologies that can be applied across a broad spectrum of industries and applications.
Digital systems, particularly microprocessors, furnish transient loads in the 100A range that a voltage regulator must service. Ideally, regulator output is invariant during a load transient. In practice, some variation is encountered and becomes problematic if allowable operating voltage tolerances are exceeded; 100A load steps exacerbate this issue. To meet this need, a closed-loop, 500kHz-bandwidth, linearly responding, 100A-capacity active load is used.
This application note from Linear Technology is based on a lecture by Jim Williams and Omar Sanchez-Felipe that investigates acoustic thermometry as an example of signal conditioning techniques. According to the lecturers, this subject has drawn enough interest that it is presented here for wider dissemination and as supplementary material for future acoustic thermometry lectures.
