Answer / nitish katoch

no we can we can only calibrate measuring devices..its
calibration is only depend upon its design

Answer / velu

Actuator can be calibrated. for example Pneumatic Actuators
are used in control valves. we have to calibrate the
Actuator as per name plate depend on the actuator size and capacity(call us bench set) for proper opening
and closure of the valve.

Answer / vinoth.s

Actuator can be calibrated. for example Pneumatic Actuators
are used in control valves. we have to calibrate the
Actuator between 3-15psi pressure range, for proper opening
and closure of the valve.
there is nothing saying whether field
devices alone can be calibrated. All process control as well
as sensing devices should be calibrated periodically.

Answer / rezvanian

You cant calibrate an actuator, you can just do setting.(
setting means better performance and more accurate ).
But calibration is the process of measuring the actual
performance of an instrument-under-test using lab
instruments ( or we can do this in the field ) that in
turn have significantly better performance than the
instrument-under-test. The measured performance is then
compared to published data sheet specifications. If observe
the instrument to be out-of-specification, instrument must
adjust and re-test .( for example we can do calibration for
a thermocouple or pressure transmitter )

A DP Endress and Hauser flow transmitter is always tripping pump at low flow. set point is 74 cubic meter/hr. Thorough impulse line flushing and zero calibration has been done, yet problem persists. What do you think is the problem and how do you rectify this fault?
