Form gauges are used to check the profile of objects; two of the most common types are radius gauges, which are packs of blades with both concave and convex circular profiles that are used to check the radii of grooves and corners, and screw-thread pitch gauges, which are blades with triangular serrations spaced to correspond with various pitches, or numbers of threads per inch or per centimetre.
It is difficult to tell how many spills have been caused by mercury gauges, which are far more widespread than the regulators, said Dr. Arnold Wendroff, a research associate at Brooklyn College's geology department, who has worked extensively on mercury poisoning.
They include dial indicators, in which movement of a gauging spindle deflects a pointer on a graduated dial; wiggler indicators, which are used by machinists to centre or align work in machine tools; comparators, or visual gauges; and air gauges, which are used to gauge holes of various types.
But low-tech tools are important too especially old-fashioned rain gauges, which are nothing more than tubes with funnels fixed to places such as rooftops.Each technique has its upsides and downsides.
The methodology proposed in this work deals with two perturbations which are usually present in strain gauges, which are sensor habitually used to close feedback control loops of flexible link manipulators.
In this study, we focus on the development of image processing techniques for wave measurement in a wave flume as a tool to replace traditional wave gauges, which are complicated to use, costly and intrusive.
In plasma fusion research the in-vessel neutral gas density is often measured using hot cathode ionisation gauges which are modified for the application in high magnetic fields and for a measurement range between 10−3 Pa and 20 Pa.
This results can be used during the designing of high-temperature X-ray and gamma-radiation detectors for radiation hot rolling thickness gauges which are widely used in the metallurgy.
But this time, officials in the department known as asset recovery -- in other words, the transit system's pre-owned parts people -- thought it might be a good idea to see if there was a higher-dollar market out there for the odd air horns, storm doors, route signs, roll signs, hand holds, train controllers and pressure gauges which were stripped off the cars.
Figure 13 shows graphs of representative specimens, which show the stresses resulting from the strain gauges, which were attached perpendicularly onto the center surface of the block and grout concrete, and the applied force divided by the total area.
