I work for a company that sells valves and valve controllers for the process industry. Each package that we design has to be tested before it can ship. To make testing faster I am building a test panel that will integrate a variety of pressure regulators, 24VDC, 12VDC and 110VAC. I am having trouble finding a 4-20mA loop calibrator. I have found many of the handheld versions but I want to build it in to the panel. The calibrator needs to be able to vary from 4-20mA with a digital display of the current and using a pot to vary it. I am not well versed in electronic circuit design but I think I am going to have to build this to get what I need. If there anybody that can help me with this project? This link provides the type of calibrator that I am looking for http://www.martelcalibrators.com/pdf/M-B_LC-100B&WDS.pdf I have looked at using a PLC but I am not sure that this is the way to go. Thanks for anyone willing to help!!
