Hello,
I've been trying to find a reasonably priced pair or LED DPMs for passively monitoring fahrenheit in a water cooling loop.
All I find are very expensive industrial or laboratory units.
I don't need programmability or control functions. Simply a thermometer.
I've found a few of this sort of unit
**broken link removed**
I've asked at three forums prior to this. I've asked each of the parts suppliers. I've searched deep into the web for information on how to mate a transducer to one of these DPMs for measuring temp.
I'm astonished and extremely frustrated that this seems so difficult to achieve. These led panels measure millivolts. A transducer produces millivolts. Some transducers are more linear than others. Some are more/less accurate. I don't need much accuracy. I'm trying to simply monitor gross changes in temp in this cooling loop. I have to use red LED dpms in this project - not LCD.
Can anyone help me figure out what type and value of transducer to use with the above unit and perhaps tell me if it's possible to simply wire them together? I'm not competent enough to design a circuit. It appears that the above unit is already a designed circuit for displaying voltage in four red led digits. Is this not correct?
I hope someone can help me. This seems like it should be so simple, it's driving me nuts!!!!!!
Thank you so much for any assistance.
