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...
The pressure transmission tube, as part of a measurement system, generally has considerable influence on its dynamic characteristics. paper deals with the mathematical modelling behaviour tubes aim providing guidelines for optimal design such systems in frequency and time domains. models used are based linear wave theory continuum flow mechanics no-slip isothermal boundary conditions. responses were evaluated terms bandwidth transient step settling rise times. Following systematic analysis...
This paper describes procedure and results of the interlaboratory comparison that was organised by Croatian national pressure laboratory (HMI/FSB-LPM) between eight accredited calibration laboratories. Comparison performed in gauge range from 0 to 2 MPa with transducer as transfer standard using gas transmitting medium. Basic aim this improve measurement methods uncertainties each participating laboratory. Analysis are given calculating deviation, En, normalized respect stated uncertainties.
<p>This paper describes a laboratory method for the determination of pressure balance piston fall rate using simple camera-based optical system with internally developed software. Measurements were carried out on three standard piston/cylinder units in Croatian National Pressure Laboratory (LPM) gas and oil as transmitting medium.<br />Measurement equipment, procedure results sets measurements are given, well an evaluation measurement uncertainty. Results compared other relevant...
It was decided at the EURAMET TC-M meeting in Torino 2006 to realize a comparison gauge and absolute pressure up 200 kPa as it would allow link CCM.P-K6 CCM.P-K2 comparisons be established. This project interested lot of laboratories from beginning with 23 participants, 22 which have submitted results. The circulation transfer standard began July 2009 lasted until January 2012. No major problems occurred during transport. measurand is effective area piston-cylinder determined 25 steps kPa....
A comparison in the negative gauge pressure range was arranged period 2011 - 2012. total of 14 laboratories participated this comparison: BEV (Austria), CMI (Czech Republic), DANIAmet-FORCE (Denmark), EIM (Greece), HMI/FSB-LPM (Croatia), INM (Romania), IPQ (Portugal), LNE (France), MCCAA (Malta), METROSERT (Estonia), MIKES (Finland), MIRS/IMT/LMT (Slovenia), NSAI (Ireland) and UME (Turkey). The project divided into two loops: Loop1, piloted by MIKES, Loop2, LNE. results loops are reported...
Low-frequency working standards of inductance are generally uniformly wound toroids on a ceramic core. Planar inductors made using printed circuit board (PCB) technology simple and cheap to manufacture in comparison toroid cores, but they significantly prone the influence external magnetic fields. In this paper, we propose design PCB standard 10 μH, consisting duplex system planar coils, electrostatic shielding, an enclosure. Alongside electromagnetic analysis procedure, measurements...
A EURAMET key comparison of the national pressure standards in range 0.7 MPa to 7.0 gas gauge was carried out. The circulation transfer standard began November 2011 and lasted until 2016. measurand effective area piston-cylinder assembly determined by measurements from MPa. As reference value, weighted mean results laboratories with primary used. With this all participants who delivered demonstrated equivalence respective value within expanded uncertainties ( k = 2) on range. were linked CCM...
This paper investigates different possibilities of measurement and control pressure in the cryostat filled with liquid nitrogen.Laboratory designed membrane regulator for automatic range from 0.9 to 1.3 bar gauge is presented.The performance special purpose evaluated through deviations set-point value their effect on thermal conditions cryostat.Results are compared values obtained using manual regulator.
