The test report summarizes the results of electromagnetic shielding effectiveness tests performed on samples of a CELL SHIELD electromagnetic radiation shield. The tests were conducted at a frequency of 9.375 GHz and found the shielding provided 91.7% plane-wave shielding effectiveness and 90.4% magnetic shielding effectiveness. The instruments and standards used to perform the tests are also listed, along with information about the calibration of the testing equipment.
Evaluation of the receiver tubes in the solar field. Receivers are a key element in the solar field of parabolic trough plants because the conversion of solar radiation into thermal energy takes place within them.
Within the next years more than 80% of the wind turbines in North America will be operating past the expiration of the manufacturer’s warranty. This means these turbines be maintained under a series of mainentence contracts. The companies responsible for the now aging fleet of wind turbines are wholly responsible for their performance and profitability. A physically small but critically important component on a wind turbine is its wind sensor. The wind sensor, or anemometer is installed atop the turbine’s nacelle and directs the controls to yaw the turbine into the wind for optimal performance.

Fireye® provides a variety of flame scanners which accurately detect the presence or absence of flame in a combustion chamber. Scanners include advanced sensors and algorithms that can discriminate a target burner from adjacent flames in the same combustion chamber. Scanners can be used with all fuel types and burner configurations. InSight Scanners® and Phoenix families are integrated designs which include all the appropriate detection and amplification circuity in one compact unit.

Abstract This paper presents the design of signal conditioning and acquisition elements of a chopped broadband radiation pyrometer. This instrument is capable of measuring temperature between 900oC and 1200oC. This work aims at solving the problem of measuring hot objects with a thermometer. The radiation pyrometer is a non-contact temperature sensor that infers the temperature of an object by detecting its naturally emitted thermal radiation. It collects the visible and infrared energy and focuses it on a detector. The detector used in this device is a thermal sensor. It receives heat energy reflected from a mirror inclined at 45o to the incident signal from the hot object. The design achieved the following: temperature range measured, from 900℃ to 1200℃; the calibrated instrument is fairly linear with a tolerable non-linearity of 3.6%, with the sensitivity of 0.014푉℃−1; the resolution was quite very small as such it can easily detect the slightest change at its input; the rotating shutter was configured to supply the chopped signal; it operates at a frequency of 50Hz that is lower than the system frequency of 200Hz; the data acquisition system was able to capture data at a periodic time of 0.02 second and below, the system operates within the specified sampling range thus, satisfying Nyquist criteria. The signal so received by the detector is translated to a human readable form and sent to a display. Keywords:- Broadband Radiation Pyrometer, Temperature Sensor, Instrument, Chopped and Detector.
