jryan Posted September 23, 2006 Report Share Posted September 23, 2006 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.pdfI have looked at using a PLC but I am not sure that this is the way to go.Thanks for anyone willing to help!!

ante Posted September 23, 2006 Report Share Posted September 23, 2006 Hi jryan,Welcome to our forum.The Martel calibrator looks expensive; you are obviously looking for a simpler solution. I had a similar question not long ago here: http://www.electronics-lab.com/forum/index.php?topic=8260.0This might be a start. ;) Quote Link to comment Share on other sites More sharing options...
