ABSTRACT The study describes significant outcomes of the ‘Metrology for Meteorology’ project, MeteoMet , which is an attempt to bridge meteorological and metrological communities. concept traceability, idea used in both fields but with a subtle difference meaning, at heart project. For meteorology, traceable measurement one that can be traced back particular instrument, time location. From perspective, traceability further implies primary realization quantity being measured terms base units...

This paper describes the development and validation of an apparatus for realization triple point argon (83.8058 K), with a novel automatic pressure control system liquid nitrogen cryostat. The controller, together custom-made software, was developed tested in Laboratory Process Measurement at Faculty Mechanical Engineering Naval Architecture, University Zagreb (FSB-LPM). Performance testing characterization controller confirmed its suitability precise reliable gauge characteristics...
Self-heating of resistance thermometers is a well-known phenomenon, which occurs when the measuring current additionally heats up sensing element. In paper, self-heating standard platinum (SPRTs) studied with special emphasis on investigation and evaluation factors contribute to uncertainty correction. The basic two-current method for correction analysed additional methods are proposed, based optimal selection currents use more than two different currents. Using advanced we can decrease from...
Thermometers in laboratory environment and industrial applications are often subject to extraneous, usually unwanted uncontrolled magnetic fields. Magnetic field influence can be minimized, but cannot fully cancelled out. Even more, most cases, there is no awareness of the existence fields, let alone their effect on measurement instrumentation. In past, sensitivity high dc fields has been investigated cryogenics at temperatures. More recently, weak was presented. The goal this paper analyse...
Abstract The subrange inconsistency (SRI) of a large ensemble long-stem standard platinum resistance thermometers (SPRTs), representative worldwide production, has been investigated for all pairs ITS-90 overlapping subranges between 83.8058 K and 933.473 K. results are reported in terms various statistical parameters to facilitate their comparison with the different authors, although test, applied one specific pair subranges, supported Gaussian distribution justified subsequent use mean...
The development and integration of measurement-automation applications in a unified software solution is analysed with particular emphasis on national measurement-standards laboratories. Measurement-automation typical measurement laboratory has several for data acquisition, processing, presentation management, which are more or less compatible each other. proposed based central database approach. concept structurally storing all the single location, where it can be dynamically accessed by...
Main text This is a report to the Technical Committee for Thermometry of EURAMET (EURAMET TC-T) on regional key comparison EURAMET.T-K9 SPRT calibration International Temperature Scale 1990 (ITS-90), from 83.8058 K (the Ar triple point) 692.677 Zn fixed point). The transfer standards used are long-stem SPRTs. an RMO linked CIPM CCT-K9. organized in five separate collapsed Stars, each one having CCT-K9 participant as pilot, which provides link KCRV Four participating laboratories involved...
From 2002 to 2004 the Consultative Committee for Thermometry (CCT) carried out a Key Comparison (KC) of water triple point cells (CCT-K7). In 2005 Regional Metrology Organization (RMO) EURAMET decided initiate an additional KC cells, EUROMET.T-K7, extend metrological equivalence larger number national metrology institutes (NMIs) from region.
The International Temperature Scale of 1990 (ITS-90) defines several different and sometimes overlapping temperature subranges. Where overlap occurs, definitions the t90 exist that have equal status but produce results. This discrepancy is called type 1 non-uniqueness or subrange inconsistency (SRI). In this paper, SRI water-aluminum/water-zinc (SRI(Al:Zn)) water-zinc/water-tin (SRI(Zn:Sn)) subranges ITS-90 were investigated for three cases. first case, calculations followed prescribed...
This paper presents a novel measuring system for detecting air gap anomalies in direct-drive electrical motors. The can be of different types eccentricity that may extreme cases result mechanical rub between the stator and rotor, potentially leading to motor breakdown. A method is proposed using sensory integrated measure its width directly either static or dynamic state. It uses an optical (OS) reflection infrared radiation rotor stator. validated by parallel employing analog Hall (AHS)...
Clinical thermometers in intensive care units are used for the continuous measurement of body temperature. This study describes a procedure dynamic uncertainty evaluation order to examine requirements clinical thermometer properties standards and recommendations. In this thermistors were as temperature sensors, transient measurements performed water air data processed investigation properties. The mathematically modelled. A Monte Carlo method was implemented evaluation. analysed static...
In-wheel motors (IWMs) as a crucial component of an electric vehicle need to be tested at the end production line, service intervals, and during motor design validation. This article presents improved synthetic loading (SL) method for rapid characterization IWMs. The proposed emulates mechanical specific operating point by current harmonic injection. We introduce novel algorithm reference setting that is based on manufacturer's data accounts motor's nonlinearities. Also, features trapezoidal...
This paper presents and evaluates a novel system for testing direct-drive motors the next generation of electric vehicles. The is adjusted to determine motor characteristics losses at high torque medium speed with accuracy. It controlled by custom-made program, which supports in various control modes working regimes under procedures due modular program structure. measurements are therefore repeatable, reproducible, can be carried out short period time. Regarding problem energy consumption,...
Abstract Mineral insulated metal sheathed (MIMS) base thermocouples experience thermoelectric drift over their lifetime caused by use at high temperatures and metallurgical changes, causing spurious measurement errors. CCPI Europe Limited University of Cambridge have designed a MIMS thermocouple with an additional inner sheath, in order to protect the thermoelements from effects that cause drift. The performance these dual-wall conventional type N K are assessed six different National...
The objective of this paper is to elaborate new elements related metrological analysis in the field testing, such as measurement uncertainty and traceability. Until now international standard ISO 45001 did not explicitly require specifications area testing an extent newly implemented ISO/IEC 17025. Therefore several additional steps should be performed specifying results, especially concerning performance other conformity assessment activities.
