What is a device that changes a voltage signal to a current signal? P/I Transducer E/I Transducer D/P Transmitter V/C Converter 2. RTD is short for: Reactive Tuning Deviation. Resistance Temperature Detector Resistance Tone Dampening. Resonant Temperature Device 3. 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 instrument 4. 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 reached 5. 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. 6. 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 elements 7. Hydrostatic head level can NOT be measured with a: dP cell resistance probe dip pipe pressure gauge 8. In this “bubbler” level control application, FI-1: sets LIC-1 setpoint. controls purge gas flow. controls gas pressure indicates purge gas flow 9. Which of the following types of actuators responds to a pneumatic signal? solenoid motor diaphragm electromagnetic valve 10. 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 thermocouple For more Knowledge please visit: Automationforum.in Automationforum.co Time's up Share your love Facebook Twitter Pinterest Linkedin
