KYOWA News! https://lnkd.in/gwRqbx-K #Dynamic_testing generally involves applying repeated load/stress/etc at high speeds to measure damage caused by fatigue or impact. Test methods include impact and fatigue tests, friction, wear, and heat tests. In order to capture the effects of these fast phenomena, a device with a high sampling frequency and dynamic range is required. In this issue of KYOWA News, we will introduce the #EDX series of data loggers, which are suitable for measuring fast phenomena. #kyowa #EDX #dynamic

In recent years, there has been an increase in the use of high-performance concrete, such as high-strength concrete and high-flow concrete. A potential problem, especially with concrete installed in the summer, is that drying due to evaporation of water from the surface can cause cracking as temperatures rise. In these cases, it is important to clarify the mechanism of autogenous shrinkage to limit cracking and improve durability. Kyowa provides two types of embedded gages effective for crack analysis of material, and foil gage suitable for strain measurement on the surface of a concrete specimen. ? #KC series gages are wire strain gages suitable for strain measurement of concrete under test. Usually, a model with the gage length over 3 times longer than the maximum diameter of the aggregate (gravel, sand, etc.) is selected for the purpose. ? #KMC series gages are designed to measure self-shrinkage and self-stress of cemented materials. They enable measurement of the self-shrinkage and high-fluidity concrete immediately after placement. 　 They are also used to effectively check for cracks of cemented materials. Usually, a T-type thermocouple is installed near the gage, while the KMC H4 type make it easier since they are equipped with a built-in thermocouple. ? #KM series gages are designed to be embedded in mortar or concrete for the purpose of measuring the internal stress. To ensure better adhesion to mortar or the like, the KM series gages feature a specially treated surface. They also provide suitable waterproofness and elastic modulus for the intended purpose. #kyowa #concrete #kmc #km #straingage #straingauge

Batch mixing and combining ‘recipes’ in industrial and commercial applications needs careful and precise control for quality control, health risk reduction and strict weighing accuracy.?Kyowa’s Load cells and weighing amplifier, (LCTA-A / WGA-680A), can control multiple hoppers and communicate with the plc using CC-Link, which also reduces wiring! #kyowa #cclink #LCTA #WGA

Wanted: Evaluation Test for #PCB’s. Almost every electronic device manufactured today uses a printed circuit board (#PCB).?Personal computers, cellular phones, digital cameras, electronic measuring instruments, car navigation equipment, automobile drive control parts.... As the complexity and number of mounting components increases, PCBs are given ever higher packaging density and at the same time they are designed to dimensional and structural limits ever smaller in size and lighter in weight. To support the evaluation of the mechanical and thermal properties of PCBs, KYOWA developed the #KFRS series gages. These gages enable PCB users and manufacturers to check whether the PCBs they use or manufacture conform with relevant standards. The strain gages can also be used to verify the reliability of PCBs by checking against company design standards. They deserve attention because they: (1) are easy to handle (2) are highly accurate (3) require less testing expense (4) are small-sized (5) yield test results immediately (6) endure severe testing environments. In combination with KYOWA measuring instruments such as the PCD-400B or EDX Series, the KFRS gages will surely satisfy all needs for evaluation tests of PCBs. #kyowa #straingage #straingauge #KFRS #PCB #evaluationtest

When strain gage transducers are used outdoors with extended cables, measurement errors occur because of cable conductor resistance, ambient temperature changes, and other factors. By using 6-wire, this error factor can be eliminated, and the bridge voltage stabilized. For example, if a 0.5mm2 multi-core cable is extended 100m, conductor resistance = 0.4Ω, resulting in a round-trip resistance of 8.0Ω in the input circuit in Figure 1. If the input/output resistance of the transducer is 350Ω, the voltage at both ends of the bridge will be e=(E?Ks?ε)/4, resulting in a decrease in sensitivity of about 2.2%. Furthermore, if the ambient temperature changes by 10°C during measurement, the voltage at both ends of the transducer will fluctuate by 0.1%, so even a load cell with an accuracy of 0.02% will lose significant accuracy. As shown in Figure 2, when two ”sense lines" are added to the bridge power supply, the Error amplifier and Control Circuit makes the bridge input voltage is constant regardless of the cable resistance r.??????????????????????????????????????????????????????????????????????????????????????????? This feature enables highly accurate and stable measurements.

Reduced scale models are often used to simulate the local conditions of larger structures where it is impractical to replicate the size or the environment or the real item.?These experiments help determine the true value of the original from the measurements on the scale model.?Because of their small size, Kyowa's #PS_pressure_sensors are very convenient products that can be embedded or processed in, for example, scale models. The small size and thin-wall structure also make them suitable for multi-point measuring of pressure distribution using a matrix arrangement of pieces.?The output can be read by any strain gage bridge amplifier. We can also provide customized pressure sensor with your bolts. #kyowa #PS #pressuresensor #small #customized

Lithium-ion batteries (#LIB’s), are used in a wide range of fields, including vehicles, communications, industry, construction, renewable energy, and mobile devices, and have become indispensable in modern life. However, excessive mechanical loads can impair the batteries performance and safety, leading to serious incidents. In recent years, research and testing of LIBs has progressed, and strain gages are now being used in testing. This time, we will introduce an article in which Kyowa's general-purpose strain gage #KFGS and large strain gage #KFEM were used in #LIB jelly roll tensile testing. https://lnkd.in/g4dZfapA #kfgs #kfem #straingage #straingauge #lithiumion #LIB
