HOW TO CALCULATE ACCURACY OF AN INSTRUMENT. WHICH IS COMPITABLE FOR USE.
sir, give me placement papers and interview quistion of birla group company of copper.
I am pujita completed Electronics and Instrumentation Engineering.As a fresher i am going to attend the interviews.Could anybody guide the topics/questions covered mostly in interviews.
why use squareroot in flow measurment by dp transmitter?
1. How many output signals do wew have in process control? 2. Could you write down the names of the pre-commissioning and commissioning stage test instruments and explain them (more than 5 items)? 3. What is the first step to commission a transmitter on service? 4. What is RTD? 5. Find the output value in MA of a temperature transmitter (RTD Type) at 120degree celius? 6. What is the O/P signal of a pneumatic transmitter? 7. What is the O/P signal of an elctronic transmitter? 8. What is the close loop and open loon?
Drum level tx with GP4 with zero elevation:7300mmh20 on HP and 8050mmh2o on LP as range but on commissioning the tx readiing is max,Why this reading?
describe yourself?
how to rectify the problem ,if we erected the DPT instrument wrongly of hp on lp side and lp on hp side?
In a gas over oil actuator, after the opening/closing of valve, how the gas is vented out? How does the hydraulic/gas circuit function?
How a conductivity sensor & analyzer work at boiler, whats the principle & science is beyond this,How conductivity sensor sence & convert signal & move toward analyzer & analyzer show reading in percent? also what is temperature compensate option in conductivity analyzer
