Thanks Jim!
1- Yes, you are correct! they are equivalent.
2- I was mistaken in the page number, it should be page 5 (for 4-wire). I have corrected that on my previous reply too. Thanks for the catch!
Many thanks Baluncore for your feedback!
The RTD that we plan to use belongs to Class A, which has accuracy defined as: Class A = ±(0.15 + 0.002* t) [-30 to 300°C] (Where t is temperature). The data acquisition module is either NI 9216 for 100 RTD OR NI 9226 for 1K RTD. Both NI devices have...
Many thanks Tom for the valuable tips! Our application is a vapor compression refrigeration cycle that involves measuring temperatures inside the pipes. The temperature media is carbon dioxide. The temperatures are relatively high (~ 200 °C). The test rig located inside a building within a...
Many thanks Baluncore for the nice explanation.
In fact to elimnate any error related to the lead resistance, we were planning to use the 4-wire RTD arrangement which I think correlates exactly with what you said about using pair of twisted cables. Using this 4-wire configuration (shown below)...
Hi all,
We are planning to use RTD (Resistance temperature detectors) for our system which basically are temperature sensors that contain a resistor that changes resistance value as its temperature changes. The RTD can come in two nominal values: either 100 ohm or 1k ohm. Knowing that the RTD...
I am trying to derive an expression for the Tension T in the massless bar in the given photo. Where there is a cart that is moving only in the x-direction and the bar is rotating around a point pivoted at the cart with angle theta. The expression that I have is deduced from:
∑ F (towards...
Homework Statement
Solve the ODE: y''+x*y'-y=0
Homework EquationsThe Attempt at a Solution
Since this is a variable coefficient ODE, I have used the method of reduction of order, and assumed the solution in the form: y=c1*y1+c2*y2
In this case: y1=x, and I have the reached the integral below...
Thank you for your comment. But the problem asks to find a general solution. So, even if it can be approached numerically, do you think this can be considered a general solution?
Homework Statement
What is the general solution of:
y'=(3*y^2-x^2)/(2*x-y)
Homework EquationsThe Attempt at a Solution
This First Order equation is neither linear nor separable. I also have checked the Exact test, which turns to be Not Exact.
Any help regarding how...
Many Thanks All for your great help.
I managed to get the answer assuming that x(0)=1, and performing the integration using partial fraction.
The final answer is:
500
---------------------------
exp(log(499) - t) + 1
I also confirmed this using Matlab.
Once again, thank you very much.
