A 1 kN·m binary dead weight torque standard machine was established at National Measurement and Calibration Center (SASO/NMCC) in 2019 by TÜBİTAK UME. Realisation of torque unit is based on the definition of torque and directly traceable to the mass, length, and time units. It is performed by a lever arm and deadweight system. The lever arm is symmetrical and supported by an air bearing. The machine has two identical and independent dead weight sets, work according to a binary system to create right and left hand torques. All dead weights are under the influence of local gravity and air buoyancy. The machine can apply torque from 1 N·m to 1000 N m with a resolution of 1 N m.
This paper describes the mechanical structure of the machine and uncertainty assessment. The relative expanded measurement uncertainty is smaller than 1 × 10−4 in the range of 1 N·m to 1000 N m.

The Absolute Gravity Italian Network project aims to update the Italian gravity network that nowadays is framed to IGSN71, established in 1971. The focal point of the project is to define a new reference for gravity with absolute gravity observations performed according to the international standardised methodology detailed in the document “CCM-IAG Strategy for Metrology in Absolute Gravimetry” (2015). IAG resolution No. 2 and subsequent, moreover establish the need to satisfy the metrological traceability also for Absolute Gravity measurements. This can be exploited by different methods such as reference sites, international comparisons of absolute gravimeters and calibration by comparison.
Measurements have been performed in appropriate sites distributed across the Italian country. The collected and validated data will be stored in an open database, as the absolute gravity database maintained by the Bureau Gravimétrique International/Bundesamt fuer Kartographie und Geodaesie when will be operative, contributing to feed the new International Terrestrial Gravity Reference System.
All the gravimeters used in the measurements participated to the international comparisons organised by CCM and/or EURAMET TC-M obtaining compatible results. However, in order to validate the results and to ensure traceability to the SI, additional comparisons between the absolute gravimeters used in the measurements have been performed just before the measurement campaign. The primary Italian reference instrument is the absolute gravimeter IMGC-02, developed and maintained by INRiM with an expanded measurement uncertainty of 8.5 μGal. The comparison sites are both located at INRiM and are provided with solid basements that guarantee good measurement repeatability and low floor noise which could ensure the final uncertainty. This paper shows the results of these measurements.

This research aims to introduce the current progress of dynamic calibration of force transducers by sinusoidal method. The acceleration measurement by absolute method is the developing direction of sinusoidal force measurement. Besides, the influence of acceleration distribution of mass block should be taken into consideration. The size, density, and Young's modulus of the mass block affect the acceleration distribution. The study demonstrates that the uniform acceleration distribution in materials like steel and cemented carbide leads to more accurate calibration outcomes, the diameter and height of the mass block have a significant influence on the distribution of acceleration. The vibration frequency of sinusoidal force directly affects the dynamic calibration result of the sensitivity of the force sensor, and the natural frequency of standard devices of sinusoidal force calibration is affected by the mass block dramatically. Therefore, it is suggested that an international standard for dynamic calibration of force transducers based on sinusoidal methods should be formulated to resolve the differences between the relevant technical standards and the requirements of calibration items and methods for force transducers among various countries. Therefore, the unified calculation method and quantity values of dynamic calibration of force transducers according to the sinusoidal method can be achieved.

For the practical needs of measuring large-scale torque in high-speed engines and wind turbines, how to reasonably extrapolate and estimate torque values, and ensure the accuracy of large-scale torque measurement results, has become an urgent problem to be investigated. In this paper, the large-scale torque extrapolation estimation problem was studied by experiment and simulation. Firstly, two different types of torque transducers were placed on the torque measurement standard device, and the torque measurement points were taken and recorded at the corresponding values of 20 %, 50 % and 100 % of the full range respectively. Then, based on the changing trend of torque value and interpolation deviation in different range, the linear extrapolation estimation method was adopted, and the estimation model of large-scale torque was established. Based on the torque data in 20 % and 50 % of the full range in the experiment, the full range torque value was predicted by simulation and compared with the results in experiment. Finally, the effectiveness of the linear extrapolation estimation method was analyzed and compared, in order to provide an effective reference for the accuracy and traceability of large-scale measurement of torque transducers.

The micro torque measurement and calibration technology is very important in the field of ships, aviation, and aerospace. Micro torque is one of the most important parameters of the key electromagnetic component of inertial navigation system, which is usually from the mN⋅m to μN·m. To measure its micro torque value, this paper introduces a standard torque device that can calibrate and measure the micro torque value of the electromagnetic components of inertial navigation systems. The device has a measurement range from 10−6 N·m to 10−4 N m, and a measurement uncertainty better than 1 % (k = 2). The device uses the micro-N·m torque calibration and measurement technology based on the flexure support, designs the ultra-thin, one-piece, and limit protection structure of the flexure support, realises the zero-stiffness support of the device, and solves the multi-degree-of-freedom torsional deformation problem of the flexure support, to make the micro-torque measurement range expand to 10−6 N m.

This paper presents the improved dynamic PTB bridge standard which now generates fully symmetrical output signals. It can be used for dynamic bridge amplifier calibration according to ISO 4965–2 and operates with all combinations of dc and carrier frequency bridge supply voltages together with simulated measurement signals that can be static, dynamic, or a combination of both. Furthermore, it can be used for bridge amplifier linearity investigations due to its good inherent linearity. Consequently, it is a universal tool for most bridge amplifier investigations and calibrations, respectively.

This paper contributes to enhance realistic sensation of a surgical training simulator using virtual reality technologies. The surgical training simulator for operating hard tissues such as bones and teeth has been developed in recent years. For enhancing the realistic sensation of the simulator, it is required to measure and model the surgical manipulation. In this study, we propose the measurement system of the chiseling operation to the hard tissue. In the proposed approach, the posture and acceleration of the chisel are measured by an Inertia Measurement Unit (IMU) sensor and the displacement is measured by a Light Detection and Ranging (LiDAR) camera. The operating force to the chisel can be detected by the force sensor installed into the chisel. The chiseling motion can be estimated precisely by the sensor fusion technology in which the sensor data is integrated. The efficacy of the proposed measurement system is verified by the experiments.

This paper summarizes the progress on enhancing the metrological performance of the Italian national standard of absorbed dose to water, a graphite calorimeter, in a water phantom, for radiation dosimetry measurements designed and built at ENEA-INMRI, National Institute of Ionizing Radiation Metrology in Italy. This constitutes the first application of graphite calorimetry in the mid-energy x-ray region, with generating voltages from 180 to 250 kV, in an effort to improve the measurement accuracy of the quantity absorbed dose to water, Dw. The design of the Italian primary standard for absorbed dose to water Dw is shown, together with a wide experimental campaign aimed at identifying the optimized instrument settings which allows improving the measurement repeatability and reducing the overall uncertainty budget.

The precise measurement of large force values, especially those above 20 MN, has always been a difficulty to be urgently solved in China and abroad, and has not been solved yet. To solve this problem, this article provides a practical and feasible method for traceability and calibration of high-precision large range force values. Using the Pascal principle, a small range testing system with known accuracy is connected to the measured large range force standard machine through a pipeline, with a hydraulic cylinder system with known surface area at both ends. The accuracy of the large range force is accurately determined through sensitivity measurement, and this method can test the friction and other parameters of the hydraulic cylinder.
