for which the error bars are the largest difference observed between the rhenium and the diamond pressure gauges (±10 GPa). The colored broad bands serve as guides to the eye and are drawn
Porepressure measurementis performed using several tools and gauges that are sent into the wellbore to precisely measure the pressure within the wellbore (recording formation pressure). This can be done in any type of porous formation that allows the flow of formation fluid into the wellbore (indee...
The bomb took forty-five seconds to drop thirty thousand feet to its detonation point, our three parachute gauges drifting down above. For half that time we were diving away in a two-g turn. Before we leveled off and flew directly away, we saw the calibration pulses that indicated our ...
I have a 10bar pressure transducer with a 4-20mA output which is showing a random variation across a span of 0.3mA (+/- 1.5mA) at a fixed pressure. This seems to me to be very large and it doesn’t seem related to electrical noise. What is the possible cause of this output fluctu...
The surface rain was recorded per minute using rain gauges, so the control of the confluence rain amount in the test range of rain gauge effectively was important for experimental success. Table 2. Operating conditions parameters of Exp.2. In the inclined plane, synchronizing the rain gauge ...
Strains along the pipe length were measured by strain gauges arranged on the pipe surface. Figure 1 shows the set-up of the burst tests. Figure 1. Schematic diagram showing (a) fatigue loading, (b) fatigue crack, and (c) denting process (used with publisher’s consent granted under ...
The von-Mises stress can be derived from the data collected by the strain gauges. The obtained results for partial yield region measured points are shown inFigure 22a,b, corresponding to the gauge arrangement in previous figures. The material yield stress is taken as the maximum value when the...
Further simplification of the calibration process could, therefore, be performed using these control units/microcontrollers and a set of known weights. 5. Conclusions We successfully fabricated an ultra-low-cost, biodegradable, and fast response multi-purpose resistive pressure sensor. A rudimentary and...
Based on the three strain gauges, pressing force (F1~3) components are acquired (Figure 3). According to forces (F1~3) and corresponding locations, the location of the resultant pressing force is evaluated using Equations (8) and (9). x = F1x1 + F2x2 + F3x3 po y = F1y1 + F2y...
