Posted on : March 13, 2018 By Sivaranjith Welcome to your Quiz. This quiz is about Loop checking Part 2 . it contains 10 questions 1. While increasing the pressure during a performance test, if you overshoot the specified test point by a small margin, you should: take the reading at the pressure you have reached. reduce pressure gradually to the test point value. reduce pressure to zero and start again reduce pressure to below the test point and increase it again until the test point is reached2. The relationship between thermocouples and thermopiles is: thermocouples consist of two or more thermopiles thermocouples consist of two or more thermopiles thermocouples only measure heat conductivity thermopile is another name for thermocouple3. Hydrostatic head level can NOT be measured with a: dP cell resistance probe dip pipe pressure gauge4. Which of the following types of actuators responds to a pneumatic signal? solenoid motor diaphragm electromagnetic valve5. In this “bubbler” level control application, FI-1: sets LIC-1 setpoint. controls purge gas flow. controls gas pressure indicates purge gas flow6. RTD is short for: Reactive Tuning Deviation. Resistance Temperature Detector Resistance Tone Dampening. Resonant Temperature Device7. What is a device that changes a voltage signal to a current signal? P/I Transducer E/I Transducer D/P Transmitter V/C Converter8. This function symbol from ISA-5.1-1984 (R1992) -- Instrument Symbols and Identification indicates a field mounted: O programmable logic controller. computer function. shared display, shared control. discrete instrument9. Changing the point of origin for input data, and the output signal destination is easy with a Distributed Control System because many changes can be implemented by: relocating wire jumpers in a junction box changing the pneumatic tubing connections reassigning inputs/outputs by changing loop configuration installing new transmitters and final control elements10. One significant advantage of single loop/stand alone digital controllers is: flexibility of configuration. 4 to 20 mA input and output capability. internal I/P and P/I transducers. imrnunity to electrical surges and lightning strikes.For more Knowledge please visit: Automationforum.in Automationforum.co Related Sivaranjith News Reporter You must log in to post a comment.
