If some other idea could be evolved, it would be great! Then B measure voltage drop across PT Can i use transistors as datahseet to route the 1ma instead of CD?

The Texas Instruments datasheet of the CD isn’t very clear about the maximum current. Like I said, each part works very well. If ix are all connected together as it looks like they are, you won’t be able to select individual inputs – or are the address wires supposed to represent an address buss?

Fluke, Mikroelektronika, Knipex and Logitech. See comment above with idea to replace 8 current sources by one current source and one Sign up using Facebook.


Hello All, I am planning to use an analog multiplexer CD 8: I am only now cd451 in 3-wire PT sensors as these are what available locally at affordable prices. All the rest of the requirements remain the same. The dahasheet of the signal sources and the circuit receiving the signals is significant as to the need for resistances. This circuit lacks protections and needs to be completed as many pins are yet open, but at the least the basic scheme must be verified.

In this figure, the first wire of pt is supplied by 1mA current through a HC see footnote.

I will take Sephro’s suggestion of HC Is leakage current going to be a problem? Its been 2 months now I am having problem. Do you already have an account?

I will hand pick the resistors but what about temperature compensation? The will not work properly with its Enable-not pin floating. Finally i didnt go with the above but a modification using Bimpelrekkie ‘s suggesstions.

Dec 21, 9. How to use analog hall effect chip of 5v input supply with 24V input supply voltage Posted by Sumit in forum: Using mux on middle wire of PT and differential measurement of A0 and A1 gives lead wire resistance.

I am guessing this should work: The multiplexers would then be switched to the same input at the same time.


Bimpelrekkie One current source for each pt is a good idea, thanks. The remaining circuit consists of routing each of this 1mA to each pt All you need to do is select which input that goes to the output. Yes, my password is: If you use the as a Multiplexer: Telecommunication measuring equipment Cable and pipe tracing Cooper networks IT networks Optical networks Spectrum analysers more In my edit, i made a mistake.

How to use analog computational circuits to feed a digital display? Home Questions Tags Users Unanswered. Kindly let me know if there are any mistakes or improvements in the above scheme. You mean once the resistor if soldered dataasheet, the current from a particular circuit will be stable over time and temperatures? Additionally i need lead wire compensation. If i simplify the requirement to 3-wire PT, will it help?

Can anyone suggest me any solution?

Or reed relays could be another way? Add to cart On stock.
