Resistance temperature detector (RTD) Almost all metals have a positive temp. coefficient of resistance so that their resistance increases with an increase in temperature. employ a sensitive element of extremely pure Platinum, Copper or Nickel wire that provides a definite resistance value at each temperature within its range.

Temperature transmitter A temperature transmitter is a device, which after measuring temperature with some kind of sensor converts the temperatures into electrical values Aditya cement uses Siemens temperature Transmitter. The transmitter is calibrated using a window based TRANSWIN package- During calibration we feed in the required data

Kiln shell temperature scanner It uses principles of non contact temperature measurement. It measures an objects naturally emitted infrared radiation to determine its temperature. Infrared radiation enters through a sensor window. A mirror rotating at 19.6 Hz receives infrared energy and reflects it on to a lens, which focuses it on to a thermoelectrically cooled detector. The detector receives energy from the target for every 90 degrees of rotation of the mirror. It is used for precise evaluation of the refractory's condition at all times. Even if a single brick falls out its location can be identified as a hot spot.

FLOW SWITCHES Flow Switches are used for visual & electrical checking of liquid flows. used in cooling ckts, lubrication ckts. It has a hinged measuring disc moving freely in the axis of the conical tube. At flowing conditions, the system adjusts so that the force acting on the disc is in equilibrium with the spring force. Each flow rate thus corresponds to a particular position of measuring disc.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
