SINGLE PHASE MEASUREMENT IN UME KIBBLE BALANCE – 3

Öz:

Kibble Balance developed in National Metrology Institute of Turkey allows the new definition of kilogram to be realized in single phase where the Faraday’s Law of Induction and Lorentz Law of Force are tested simultaneously thanks to its design with moving magnet. Although there are numerous advantages of this design, like being less sensitive to environmental and experimental conditions, there appear the problem of distinguishing the voltage induced across the ends of the coil as a result of Faraday’s Law of Induction and the voltage due to the current delivered to coil to generate the Lorentz Force, with a relative uncertainty of some parts of a billion. In order to get the best possible performance of the digital multimeter measuring the voltage of the coil, a waveform generator is connected in series to the multimeter as a compensating voltage source so that the voltage due to the supplied current is almost eliminated in the input of the multimeter. However, temporal voltage fluctuations in the waveform generator may induce additional voltage at the coil. In this paper, we show that these random effects are eliminated with an uncertaınty of 15 ppb in case the experiment lasts for at least 48 hours.

UME KİBBLE BALANS – 3 İLE TEK FAZDA ÖLÇÜM

Öz:

Türkiye Ulusal Metroloji Enstitüsü'nde geliştirilen Kibble Balance, hareketli mıknatıslı tasarımı sayesinde, yeni kilogram tanımında Faraday İndüksiyon Yasası ve Lorentz Kuvvet Yasasının aynı anda test edildiği tek fazda ölçüme olanak tanıyor. Bu tasarımda, çevresel ve deneysel koşullara daha az duyarlı olması gibi sayısız avantaj olmasına rağmen, Faraday İndüksiyon Yasasının bir sonucu olarak bobinin uçlarında indüklenen voltaj ile akımdan kaynaklanan voltajı milyarda birkaç bağıl belirsizlikle ayırt etme sorunu ortaya çıkmaktadır. Bobin voltajını ölçen dijital multimetreden mümkün olan en iyi performansı elde etmek için, kompanzasyon voltaj kaynağı olarak multimetreye seri olarak bir dalga formu üreteci bağlanır, böylece akımdan kaynaklanan voltaj, multimetrenin girişinde neredeyse ortadan kalkar. Fakat, dalga formu üretecinde zamana bağlı voltaj dalgalanmaları, bobinde ek voltajı indükleyebilir. Bu yazıda, deneyin en az 48 saat sürmesi durumunda bu rastgele etkilerin 15 ppb belirsizlikle elimine edildiğini gösteriyoruz.
