    DVRT Temperature compensation?

    Thanks for the ideas, VE1BLL, I have contacted the manufacturer for circuit ideas and I even purchased one of their amplifiers but they use a monolithic chip for part of the circuit (which doesn't work to high temperature) and they also have a patent on some of the circuitry so they are a bit...

    DVRT Temperature compensation?

    Another question just came to mind, how would I go about finding a matching temperature coefficient to my sensor?

    DVRT Temperature compensation?

    I have contemplated the microcontroller approach, but I would rather have the analog signal be as free from drift as possible, I know I have tested the results with just the sensor under heat and seen a resulting drift in the output. I am driving the bridge with AC, but have one side pulled to...

    DVRT Temperature compensation?

    Yes, that is what I am doing but I am using resistors to complete the bridge, could this possibly be the source of my problems?

    DVRT Temperature compensation?

    Has anyone else out there ever worked with a DVRT as a displacement sensor at high temperature? I am currently doing so, and have electronics that operate up to 175°C but there is drift, mostly due to the resistance change of the windings of the sensor. Does anyone have any ideas/techniques...

    RG6 versus RG58

    Thanks - that is a great reference! [noevil]

    RG6 versus RG58

    Thanks, BrianR - that gives me a good amount to work with - I suppose if I wanted to get really detailed in my anlysis of this, I should dust off my transmission cable textbooks and find the formulas I need - I just wasn't sure of all the ratings for these types of cables. BTW the actual...

    RG6 versus RG58

    Hello to all; I'm looking for some info on the coaxial cable standards for RG6 and RG58. I have been able to see that the RG58 is a 50 Ohm cable and the RG6 is a 75 Ohm cable. What I was really after, and I was unable to find was an accurate comparison of the distance propogation...
