The MT-QLP production instrument produced in the United States has three caliber arms. The three arms are mechanically combined together, and they together drive the linear potentiometer to change with the caliber. The output voltage of the linear potentiometer is proportional to the tangent of the opening angle of the caliper arm; the linearity is best when the caliber value is 114254mm. This range is sufficient to meet the requirements of coal field geological exploration. However, because the three measuring arms are linked, there is still some distortion in describing the irregular collapse. Factors affecting measurement accuracy. The influence of measurement accuracy can be divided into two major factors: first, the scale accuracy of the instrument, which is the basis for improving accuracy, regular indoor calibration calibration, real-time calibration before and after measurement is the guarantee to improve the measurement accuracy; Second, the accuracy of real-time acquisition.
Influencing factors in real-time acquisition: (1) Use a small-diameter inclinometer to measure large-diameter wells (or wells with irregular walls), due to the state of the downhole instruments (adhesive, centered, eccentric parallel, eccentric not (Parallel) is unknown, and there is uncertainty in the resulting inclination and azimuth. The molecular beam epitaxy is therefore more likely to be distorted. (2) Magnetic interference from the well site (derrick, drilling tool, generator, etc.) brings many difficulties to the calibration before and after logging and the initial angle setting; within 5m near the derrick, it can cause compass positioning 20b For the above error, it is necessary to select a place 30m away from the derrick for calibration. Magnetic interference from the cable. When the inclination of the drill hole is not large, the magnetic interference of the cable is negligible. When the inclination of the drill hole is large or in the directional inclined hole, the magnetic interference caused by the cable should be paid enough attention (magnetic The interference has no effect on the piezoelectric gyroscope). It is difficult to evaluate the influence of magnetic interference on the measurement accuracy, but the influence of this interference on the azimuth is more obvious when the instrument is calibrated.
Other Custom Headers Overview
Custom Headers provide design flexibility, production efficiency while decreasing needed equipment assets
Antenk custom header family offers complete design flexibility to modify standard headers or develop new customized connectors to meet specific design requirements. Use the Custom Header Configurator or contact Antenk to find a custom header solution that caters to a wide variety of programs and volumes.
When OEMs perform pin insertion onto PCBs, they need to invest in stitching machinery to do so, and that increases manufacturing costs. Custom Headers make pin insertion unnecessary and eliminate the need for customers to invest in stitching machinery.
OEMs often look for ways to simplify their manufacturing processes to reduce costs and get products to market more quickly. Custom Headers reduce steps manufacturing process by providing headers with pins already inserted.
While press-fit headers typically meet automotive standards, the interface isn`t the most robust available. Soldered termination not only meets automotive standards, it also provides a stronger interface than press-fit.
