The temperature and Pressure sensors play a vital role in Nuclear Power Plants (NPP). The Rosemount temperature sensor helps to produce the exact temperature and pressure measurement of the nuclear power plant. The sensors that supply real data must respond quickly to the safety systems of NPP. In this paper, first the Dimensionality of the Original dataset is reduced by using Principal Compone...

Fibre Bragg grating (FBG) temperature sensors have already shown short-term radiation tolerance in nuclear environments. However, the effect of long-term irradiation needed to be investigated. We therefore characterized multiplexed FBG temperature sensors inserted early 2000 in an irradiation channel of a low flux nuclear reactor. After 50 months, we show that the sensors still operate satisfac...

The well known TVO temperature sensors were irradiated by a gamma source up to the total dose of 0.1, 0.3 and 0.5 MGy. After these experiments the postradiation behaviour of the sensors was estimated. Besides, several tests of the TVO-carbon sensors with different specific sensitivities were carried out in the magnetic fields (parallel and perpendicular to the sensor package) up to 9 T in the t...

In this paper, we describe a method of optimum temperature modulation of metal oxide semiconductor (MOS) based gas sensor, operated in dynamic temperature measurement for identification of gas. The volatile organic compound (VOC) sample space consists of fourteen laboratory chemicals sampled at various concentration. We have used eleven number of gas sensors, manufactured by Figaro sensors, Jap...

Biomedical sensors, called invivo sensors, are implanted in human bodies, and cause some harmful effects on surrounding body tissues. Particularly, temperature rise of the invivo sensors is dangerous for surrounding tissues, and a high temperature may damage them from a long term monitoring. In this paper, we propose a thermal-aware routing algorithm, called least total-routetemperature (LTRT) ...

Current WPSM research is focused on developing a set of wearable, minimally-invasive sensors that monitor and collect raw data on five elements of a warfighter’s physical and mental function: core body temperature, hydration, cognition, injury, and life signs (heart, respiratory, and activity rates). Sensors would also collect data on variables that affect physical and mental function, such as ...

Advancement of gas sensor technology over the past few decades has led to significant progress in pollution control and thereby, to environmental protection. An excellent example is the control of automobile exhaust emissions, made possible by the use of oxygen gas sensors. Since early 1970’s there have been sustained studies on oxygen sensors and has led to development of sensors for various a...

In recent years, thermal sensing in digital devices has become increasingly important. From a security perspective, new thermal based attacks have revealed vulnerabilities in digital devices. Traditional temperature sensors using analog-to-digital converters consume significant power and are not conducive to rapid development. As a result, there has been an escalating demand for low cost, low p...

Fiber-optic interferometric sensors based on graded-index multimode fibers have very high refractive-index sensitivity, as we previously demonstrated. In this paper, spatial-frequency multiplexing of this type of fiber-optic refractive index sensors is investigated. It is estimated that multiplexing of more than 10 such sensors is possible. In the multiplexing scheme, one of the sensors is used...
