Greetings,
Would like to know the reason for the inclusion of a bypass
line at the outlet of a L.P. steam coil on an AHU.
Obviously a strainer is in front of the F&T Trap on the
return piping but after the F&T a 3/4" line runs back to the
coil outlet. This line is fitted with a check which is...
Hello all,
To anyone who may be interested.
I wish to demonstrate a P/I Transducer which when fed an input
of 4-20mA will output to a pneumatic actuator an air signal of
3-15psig. I need to be able to generate a signal of 4-20mA.
I seem to recall that 10volts and a 500ohm resistor will produce...
Hello all!
For anyone who may be interested,
I wish to demonstrate a P/I transducer which receives an input signal of 4-20mA and uses a 20 psig air signal to produce an air signal out of 3-15psig to some pneumatic actuator, such as a damper
motor or a modulating valve.
Is there an inexpensive...
