Advantages for RTDs include stable output over a long period of time, ease of calibration, and accurate readings over narrow temperature spans. Since liquids have a property of self draining. Gas Service: On gas service the transmitter is mounted above the orifice plate because Gases have a property of self venting and secondly condenlate formation. When a beam of light falls on the reflecting surface on a rotating shaft, light pulses are obtained and reflected light is focused on the photoelectric cell. Q.13. These objective type Electrical and Electronic Measurements & Instrumentation questions are very important for campus placement test, semester exams, job interviews and competitive exams like GATE, IES, PSU, NET/SET/JRF, UPSC and diploma. Flow varies directly as the square root of different pressure F = K square root of ΔP. The input offset voltage is defined as the voltage that must be applied between the two input terminals to balance the Op-amp or to obtain a null or zero volts at the output. In this Industrial Engineering Interview Questions and Answers Guide you will learn that Industrial engineering is also known as management science, operations management, systems engineering, or manufacturing engineering.
