Superheater Metal Temperature Measurement

open access: yesMeasurement + Control, 1970
With the insistence of the Electricity Boards that Boiler manufacturers be responsible for installation of metal temperature measuring equipment, it is necessary that the companies should be in a position to implement this requirement.

Infrared Thermopile Temperature Measurement Technique in Microwave Heating Systems [PDF]

open access: yesJournal of Chemical and Petroleum Engineering, 2018
Temperature measurement in microwave systems is essential for thermally driven processes, namely, catalytic reactions and ceramic sintering. Although, the application of direct thermometry methods, namely, thermocouples, have been commonly articulated in

Statistical Assessment and Temperature Study from the Interlaboratory Application of the WLTP–Brake Cycle

open access: yesAtmosphere, 2020
The relative contribution of brake emissions to traffic-induced ambient Particulate Matter (PM) concentrations has increased over the last decade. Nowadays, vehicles’ brakes are recognised as an important source of non-exhaust emissions.

Lead-Wire-Resistance Compensation Technique Using a Single Zener Diode for Two-Wire Resistance Temperature Detectors (RTDs)

open access: yesSensors, 2020
In remote measurement systems, the lead wire resistance of the resistance sensor will produce a large measurement error. In order to ensure the accuracy of remote measurement, a novel lead-wire-resistance compensation technique is proposed, which is ...

Bi-Signature optical spectroscopy for online fault detection in electrical machines

open access: yesThe Journal of Engineering, 2019
A novel bi-signature optical spectroscopy for fault detection in electrical machines is presented. The combined use of long period grating (LPG) and two fibre Bragg gratings (FBG1 and FBG2) is implemented to discriminate between vibration and temperature

Permittivity measurement of thermoplastic composites at elevated temperature [PDF]

open access: yes, 2001
[Abstract]: The material properties of greatest importance in microwave processing of a dielectric are the complex relative permittivity Epsilon = Epsilon' - jEpsilon'', and the loss tangent, tan Delta = Epsilon'/Epsilon''.

Calculation of the Anisotropic Coefficients of Thermal Expansion: A First-Principles Approach [PDF]

open access: yes, 2019
Predictions of the anisotropic coefficients of thermal expansion are needed to not only compare to experimental measurement, but also as input for macroscopic modeling of devices which operate over a large temperature range.

Effects of lattice misfit of γ/γ′ phases on hydrogen embrittlement behavior in Ni-based single crystal superalloy

open access: yesJournal of Materials Research and Technology
The effect of γ/γ′ phase lattice misfit on hydrogen embrittlement (HE) behavior was fundamentally investigated by utilizing a Ni-based single crystal CMSX-4 superalloy with a simple microstructure that can exclude the H-trapping effects of grain boundary,
