pressure switch range 0 to 2bar.i have to install from
ground level to 5 meters height.what is the formula the to
increse the range ? and every 1 meter how much pressure
should be add ?

Answer / rajkumar.diice
At first you
should know
clearly the
correct fluid
density. If you
are working with
water; the water
density is
1000kg/m3.
Multiply this
with the tank
height 5 meters
then the
pressure acting
on switch at
liquid level 5
mts will be
5000mmWC, set
switch setting
at .5 bars. If
you are looking
to switch a
motor off
automatically
means use NC
contact.

Answer / mrmk
It depends upon the tapping point.In your case if the
tapping point is at ground level and pressure switch
installed above ground level then no need of any
compensation.

How do you calibration D.P transmitter? ?
Generally in which location ( JB or IO card or DCS) the thermocouple compensation is done.Also where they measure the atmosphere temp ( for compensation) in JB OR DCS panel? How they compensating that atmosphere temp? is any circuit for that ( like in rtd wheatstone bridge)?
i have done DAE in Instrumentation and Process Control. i have applied for an apprentice training in chemical company after three day my interview will be conduct but i need more information about industrial process control and controller. my e mail is imran_dilsetu@yahoo.com please tell me interview question relative to instrumentation ?
A temperature sensor (RTD) connected via a temperature transmitter is adjusted to give an output of 4ma at 60 deg and 20 ma at 600 deg. This output (4-20ma) from the transmitter is connected to an IGBT-inverter to control a high speed (-12,000 to +12,000 RPM) DC motor. And in the inverter it is programmed as, for 4ma the motor speed will be -3,000 RPM and for 20ma the motor speed will be +10,000 RPM. The question is : If the motor speed is +5,500 (RPM), what will be the temperature? (-sign indicates that the motion is in reverse direction).
