Can anyone suggest a recognized standard (ISA, IEEE,...) that provides information on sizing 4-20mA process control wire? I am specifically looking for a recommended maximum voltage drop for the wire using a 24VDC, two conductor circuit.

I am using an industrial interface controller that contains real time data such as flow rates and pressures. I am new to web development and this interface is also a web server. I am able to display the data using SSI and CGI commands in the web pages I create on the server. I'm using commands...
Does anyone know of any specific plumbing codes that specify stainless steel pipe material grades permissible for potable water? I'm mainly interested in codes for use in cold water applications and limitations that may apply.
Thanks.

I am trying to generate a list of results from a list of values by plugging each value into a formula to calculate the result. My list of values is quite extensive so I would like to have Excel increment through the list and produce a result for each, thus generating a respective list of...
I am looking for a way to allow my Mitsubishi FX2N PLC to link to a BACnet network (and/or LonWorks). I have found plenty of protocol converters but either the serial protocol does not match or networking format is not compatible. Does anyone have experience with this or know where I might go to...
Is anyone aware of an output filter/choke capable of limiting dV/dt to 500V/microsec.? I have a submersible motor application with a maximum of 200ft. wire run between the drive and the motor. This is a 460VAC/3ph./60Hz. application operating a 75Hp motor. The filters I’ve reviewed thus far are...
Does anyone know if there is a published standard that provides guidelines for routing process signal wires (4-20mA)? This would be as opposed to power wiring (e.g. route signal wire in separate conduit, separated by a distance...). Thanks.

I am in search of an odd WROT Copper fitting that I have been unable to locate. I need a copper reducer, cup x fitting (CxFtg) in sizes 3x2.5in. and 3x2in.. I am using type “L” copper pipe with 175psig max. working pressure. Does anyone know where I can find such a fitting? Any help you can...

I am developing a manufacturing procedure for installing vfd’s on our equipment. I am specifically looking for a standard or code (ISA, IEEE, etc.) that gives guidelines on routing process control signal wires to power equipment, such as 4-20mA speed signals to vfd's. I would like to use more...
