i/p converter always for supply pessure from 3~15 psi only !! And from where this converter bleed the air.
2 5536My flow transmitter range is 0-1000mmwc.DCS range is 0- 100m3/hr.What is correspond out put in terms of milliamps if my flow is 65m3/hr
4 9690Coriolis flow meter coil supply is 24vdc but why still we given 230ac for this transmitter let me explained detailed review please
1 4857Q1: Consider part of a control loop, which excludes the transmitter, consisting of a process, a controller and a control valve which may be represented by two dead times of 0.5 min each and three exponential lags of 0.8 min., 1.0 min. and 1.5 min. respectively. We wish to express this system as an overall first order plus dead time (FOPLD) model ie gain, time constant and process dead time. (We will see later that this is often done, to simplify controller tuning). For this exercise, gain is considered to be 1.0. (A) If the transmitter is a flow transmitter whose behaviour can be described by a dead time of 0.2 min. and an exponential lag of 0.5 min. in terms of the overall dead time and overall first order lag how can the system behaviour be approximated ? Overall dead time = Overall time constant = (B) If the transmitter is a temperature transmitter with a temperature sensor in a protecting well whose behaviour can be described by a dead time of 0.7 min. and an exponential lag of 15 min. how can the overall system behaviour be approximated now? Overall dead time = Overall time constant =
19931)why we are using mostly Ultrasonic Flow meters to measure flow, rather than Radar waves? 2)why we are using Ultrasonic waves and Radar waves to measure the Level?
NTPC,
1 4784Air pressure in a pressure vessel can rise or fall at up to 2.5kpa/s.The pressure is sampled every 0.5 seconds.If range of the the pressure indication is 0 to 1500 kPa, what is the max value of the error due to sampling in % of Span
2 4387a pressure transmitter with a range of 0 to 2500kpag has a specified accuracy of 0.5 % of span.It is to be calibrated using a comparison gauge to have an accuracy of 0.1% of span.The comparison gauge has a range of 0 to 3000kpag What is the accuracy ratio? is this ratio acceptable?

What is intrinsic safety mean.
I am teja. I am studying Msc(tech) Electronics and Instrumentation (3years course) in Andhra university. But my course is not recognised by UGC and AICTE. Please tell me the job opportunities after this course. And i fineshed PLC course in IGIAT ,Vizag.Also complted my short term coure in SCADA, Seimans WinCC in ATI,Hyd.After Msc can i join Mtech for good job? or phd. How i can get good job in INdustrial Automation Side. Please give replay.Because this is my life matter.

Lux meter is the measuring device to measure the lux level of lighting fixture. in industrial sector two types of lighting fixture is being used as street lighting purpose 1. HPSV (Sodium) and 2. HPMV (Mercury). HPMV having white light which is an combination of red, blue and yellow colour, while HPSV haivng Yellow lighting. in HPSV red & blue colour will be absent. during measurement of the lux level of HPSV and HPMV fixture. 1. Lux meter can measure the actual lux level of both fixture? 2. or it will show false reading for HPSV fixture light as it has only yellow light present. please give me answer

i have used level transmitter in starch cooking preparation tank. tank total height 2mtr.sometime LT display shows some error value when tank is fully empty and diaphragm side i already checked okay no problem in diaphragm area. field cable checked 24volt and mA shows correct value while tank empty mA is 4mA. 4mA i needed that 0% but display showing 10% or 15% percentage values are varying continously please give any good solution for me.....
