PEU Posted September 29, 2004 Report Share Posted September 29, 2004 Hi, this is my 1st post in the forum.Is there any circuit/PCB available to measure milivolts, like the 3161/3162 or 7106 with the option to send that info via rs232 using a max232 or similar?Thanks Quote Link to comment Share on other sites More sharing options...
MP Posted September 30, 2004 Report Share Posted September 30, 2004 RS232 is a communication protocol. You will need something to implement this. Since you are talking about millivolts, I would use a micro with an Analog to Digital Voltage converter built in.MP Quote Link to comment Share on other sites More sharing options...

Kevin Weddle Posted October 1, 2004 Report Share Posted October 1, 2004 Any of the electronics devices can be used in the millivolt range. In fact the uV range. They are presumed very accurate in terms of the voltage they exhibit. When you say measure, I am assuming you want to convert the voltage to a display. So you might use a device set to trigger at a threshold. This is a comparator. Not an opamp but a special opamp. An assortment of these will create a window of voltage for you.
