High Temperature Humidity Sensor Calibration
2002The request of calibration of humidity sensors at high temperature and high relative humidity is quite common in many industrial sectors (food, pharmaceutical, etc.) and in environmental monitoring applications. However, in spite of a widespread traceability need in such measurement conditions, only few calibrations or industrial laboratories are ...

High Temperature, High Pressure Water Level Sensor
1980 Ultrasonics Symposium, 1980A sensor was developed to measure water level over a range of 750 mm with an uncertainty of +- 20 mm at a temperature from 20 to 250/sup 0/C and pressure up to 15.2 MPa. The sensor is type 304, flattened stainless steel rod. Its cross section is 1.6 x 3.2 mm, and its measured torsional transit time is a function of water density rho, level L, and ...

CdSe(ZnS) nanocomposite luminescent high temperature sensor
Nanotechnology, 2011High temperature luminescence-based sensing is demonstrated by embedding colloidal CdSe(ZnS) quantum dots into a high temperature SiO(2) dielectric matrix. The nanocomposite was fabricated by a solution process method. As-prepared CdSe(ZnS) quantum dots in the nanocomposite sensor show an absorption band at a wavelength of 600 nm (2.06 eV ...

Ionic Liquid High-Temperature Gas Sensor Array
Analytical Chemistry, 2006A novel sensor array using seven room-temperature ionic liquids (ILs) as sensing materials and a quartz crystal microbalance (QCM) as a transducer was developed for the detection of organic vapors at ambient and elevated temperatures. Ethanol, dichloromethane, benzene, and heptane were selected as representative gas analytes for various kinds of ...

High Performance Temperature Sensor
2004Periodically poled lithium niobate LiNbO3 waveguides (PPLN-WGs) are investigated via a home-made computer code to perform efficient frequency conversion of lightwave, through the quasi-phase matching (QPM) of the modes propagating at the fundamental and second harmonic wavelengths. The design goal consists in obtaining a temperature sensors having high

High pressure and high temperature acoustic sensor
The Journal of the Acoustical Society of America, 2009An acoustic sensor, such as a hydrophone, is deployable in a fluidic media having high temperature, high pressure, and/or potentially caustic chemicals. The hydrophone includes a housing filled with an internal fluid and containing a sensing mandrel. The sensing mandrel senses the acoustic pressure transmitted to the internal fluid through a diaphragm.

High-Temperature Sensors for Small Gas Turbines
1968Abstract : The report describes an experimental program performed to generate technology on high temperature sensor concepts for small gas turbines. Major emphasis was placed on the definition of material systems needed for transducers with long life, good reliability, and fast response for sensing turbine inlet temperatures in the range of 2200 to ...

Optical temperature sensor for high voltage applications
Applied Optics, 1982An all-dielectric, electrically passive, optical temperature sensor for use in high voltage environments has been constructed and tested. It is based on the temperature dependence of the optical activity in crystalline quartz. The sensor showed excellent linearity over the 20-180 degrees C temperature range, providing temperature measurements within ...
