最近の話題
真のRMSメーターの必要性は、回路内の非正弦波の可能性が近年大幅に増加したために高まっています。 いくつかの例には、可変速モータードライブ、電子バラスト、コンピューター、HVAC、およびソリッドステート環境が含まれます。
最大 50 m 離れた場所から漏れ箇所を正確に特定できる漏れ検知テクノロジーがあるとしたら、どうでしょう。Fluke ii900 産業用超音波カメラは、圧縮空気の漏れを確実に検知する「革新的製品」です。
Clamps measure current. Probes measure voltage. Having a hinged jaw integrated into an electrical meter allows technicians to clamp the jaws around a wire, cable and other conductor at any point in an electrical system, then measure current in that circuit without disconnecting/deenergizing it.
The difference between an oscilloscope and a digital multimeter (DMM) is simply stated as pictures vs. numbers. Learn more, including when to use each.
クランプメーターは、DMMで適用のミリ単位ではなく、小数第2位を四捨五入した単位で測定します。
Using a megger for insulation resistance testing capacitors and high voltage components.
If your compressed air system is under-performing, your connected equipment will be too. Learn how to monitor and prioritize which air leaks to fix using the Fluke ii900 LeakQ mode.
Compare IP rating, battery life and other features. What is the difference between the Fluke 87V MAX and the 87V digital multimeter?
Take digital multimeter safety precautions to handle the conditions found in your work environment. Understand multimeter CAT ratings and ingress protection (IP) codes.
正しく測定を行えるマルチメーターを使用することが重要です。これらの測定値の意味を知ることは、さらに重要です。正確性と精度により、取得した測定値が有用であることが保証されます。精度が高いほど再現性が向上し、正確性が高いほど測定値が完璧に近いことを意味します。
Oscilloscopes sample signals as they change over time and then plot those signals on a display. The amplitude of the signal is plotted on the vertical axis and time is displayed on the horizontal.
200 馬力のコンプレッサーで生成した圧縮空気で約 400 個のツールを稼働する 13,935 平方メートルの工場で導入されている、空気漏れ検知器による機器停止の防止策についてご覧ください。
What is power factor and why is it important? Learn how to calculate the power factor formula, each component of the equation, and why it matters.
ツールや工程の稼働に圧縮空気が不可欠な生産ラインでは特に、ごく少量の空気漏れでも、製品やエネルギーの無駄と生産時間の損失につながります。
What is the difference between an insulation tester and a megohmmeter? Compare insulation meters, testers, megohmmeters, and meggers to learn about what's best for your needs.
One would be hard-pressed to find a facility manager who doesn’t want maintenance operations to run as smoothly as possible. Detecting signs of motor components failure becomes easier when combined with a preventive vibration program.
Transformers supplying nonlinear loads should be checked periodically to verify operation within acceptable limits. Transformers are also critical to the integrity of the grounding system.
Thermal cameras provide a return on investment
Sometimes vibration in industrial equipment is a symptom or even a cause of trouble; other times, it is part of normal machine operation.
Vibration can result from a number of conditions, acting alone or in combination. Keep in mind that vibration problems might be caused by auxiliary equipment, not just the primary equipment.
Vibration testing for condition-based maintenance, to reduce costs and production losses. Mechanics of testing, analyzing roller bearing faults.
Infrared (IR) thermometers enable you to measure temperature quickly, at a distance, and without touching the object you're measuring. They are so useful, easy, and even fun to use that they have become as common in kitchens as they have on factory floors. Infrared thermometers are often used to find overheated equipment and electrical circuits, but they have hundreds of other uses.
Find out how the pass/fail testing function captures random glitches.
The Fluke 15x7 Series Insulation Multimeter is a new category of test tool that combines a full featured True RMS DMM and a megohmmeter. It's an integrated tool for maintaining and troubleshooting motor systems, electrical distribution, and production equipment.
