Answer / jccarlisle

An I/P transducer is a device which converts a current
signal (usually 4-20mA) to a pneumatic signal (pressure
depends on actuator size requirement). The pneumatic signal
goes either directly to control device (valve, damper, etc)
for operation of the device or to a positioner which
measures the amount of mechanical travel of the control
device and adjusts the input until the exact percentage of
movement called for is achieved.

An E/P is a device that integrates both devices above into
one unit.

Answer / pavan

i think i/p
converter
converts current
in to
pressure,where e/
p converter
converts voltage
to pressure.

Answer / somaraju

if varing voltage with a constant current it is E/P
if varing current with constant voltage it is I/P

Answer / mike betts

My understanding that the IP positioner would be that you
are using a current signal (I) and converting it to a
pressure signal (P) in order to operate a positioner valve.
I would call the signal conditioner in this case an I to P
converter.

I am not so sure about EP, but E can be used to mean EMF
which is measured in volts and so could ve voltage to
pressure signal conditioner in the same way as I to P in
the example above.

Answer / dennis

The "E/P" elector-pneumatic positioner is used for
operation of pneumatic rotary valve actuators by means of
electroller or control systems with an analog output signal
of "DC4 to 20mA" or split ranges.
I/P not sure yet.

Answer / rahul dhumal

E/P is combination of I/P & positioner i.e. the o/p pf E/P is directaly given to the valve actuator.
And in the case of I/p 4-20ma is given to it & output of I/P is given to the positioner .

Answer / s.m.patel

I to p means input signal is 4-20MA
E to p means input signal is 0 to 10 VDC

Answer / xyz

i/p is a converter and e/p is a positioner
