Th igned prepiicaly for nd beaker. - The board require other OMEGA TYPE Measurement 4 ra apparatus like Neal? e on ; this set up carri Practical experien® p '8S great educative value for Science and Engineering students: OBJECT Measuremen FEATURE : a The unit consists of following built in parts: and control of temperature using RTD transducer 01 ev pcat 100 mA, IC Regulated Power Supply. 02 Four Op-Amp. ICs- 03 Relay6V DC, one change over. 04 One NPN transistor. 05 31/2 digits display panel meter, to display temperature in °C. 06 RTD sensor with 3 pin connector. 07 One switch for setting temperature on one side and to read actual temperature on other side 08 Potentiometer to control temperature. 09 AC mains socket to connect load whose temperature is to be controlled. 10 Adequate no. of other Electronic Components. 41. Mains ON/OFF Switch and Fuse 400 mA. 42 The unit is operative on 230V +10% at S0Hz AC Mains. 13 Good Quality, reliable terminal/sockets are provided at appropriate places on panel for connections/observation of waveforms. OTHER APPARATUS REQUIRED 01 Heater 1000 W 230V 02 Beaker THEORY The resistance of a conductor changes when its temperature is changed. This property is used for Measurement of temperature. The variation of resistance (R) with temperature (T) can be represented by following relation for most of the metals as : ReRo(t+Llot + Where Ro = Resistance at temperature T = 0 And 4, ba, Lg are constants.
