# Thermal Sensors Lab

Thermal Sensors Lab

In a processing plant, a chemical tower has a liquid which is vaporized.
However, if the vapor in the tower reaches 150Â°C, an alarm needs to be
generated so that safe shutdown of that system of the plant may be initiated.
An RTD will be used to measure the temperature of the vapor. The RTD will
generally operate between 80Â° to 175Â°C and has a resistance of 220? at 20Â°C.
The fractional change in resistance per 1Â°C is 0.0040. The dissipation constant
is 25mW/Â°C. Design a circuit to activate an LED alarm when the temperature
reaches 150 Â°C. The error should not exceed +/-1Â°C. Use a single supply
voltage.
a.
Draw a block
diagram for your design. Explain the function of each block and why it is
needed.
b.
Design the
circuit showing all calculations. Choose standard resistor values, and specify
the tolerances. Provide a drawing of your circuit with all resistor values and
tolerances and parts. You may do this by creating it in Multisim and then
drawing the values on as appropriate.
c.
Construct the
circuit in Multisim using the resistor values you chose and tolerances. Do a
screenshot showing how you have set up the tolerances for the resistors. For
the RTD, you may use a potentiometer or variable resistor for which you can
change the resistance for different temperatures. If you have a bridge circuit
with a potentiometer for nulling, explain how you decide what resistance to use
for the null.
d.
Create a table
of temperature, RTD resistance, RTD resistance adjusted for self-heating, LED
Status. Test your circuit, and use the table to display your results. Find the
precise resistance and temperature at which the LED turns on. Provide several
screenshots showing the resistance which reflects the RTD resistance value used
in the circuit and the LED alarm. Which RTD resistance do you use in the
circuit for testing?
e.
Put together all
of the above in a well-written report including introduction, requirements,
block diagram, design calculations, final design (including any potentiometer
settings), testing (including which RTD resistance is used in the circuit for
testing), and analysis of results. Be sure to provide a summary at the end,
noting at which temperature the alarm was activated, if this was as designed,
and what accounts for differences. Please note any problems you encountered.
f.
Entitle your
report as EE372W3LYourGID.docx (or other word processing document). Save your
Multisim file as EE372W3LYourGID.ms. Submit both documents.

# Our Service Charter

1. ### Excellent Quality / 100% Plagiarism-Free

We employ a number of measures to ensure top quality essays. The papers go through a system of quality control prior to delivery. We run plagiarism checks on each paper to ensure that they will be 100% plagiarism-free. So, only clean copies hit customers’ emails. We also never resell the papers completed by our writers. So, once it is checked using a plagiarism checker, the paper will be unique. Speaking of the academic writing standards, we will stick to the assignment brief given by the customer and assign the perfect writer. By saying “the perfect writer” we mean the one having an academic degree in the customer’s study field and positive feedback from other customers.
2. ### Free Revisions

We keep the quality bar of all papers high. But in case you need some extra brilliance to the paper, here’s what to do. First of all, you can choose a top writer. It means that we will assign an expert with a degree in your subject. And secondly, you can rely on our editing services. Our editors will revise your papers, checking whether or not they comply with high standards of academic writing. In addition, editing entails adjusting content if it’s off the topic, adding more sources, refining the language style, and making sure the referencing style is followed.
3. ### Confidentiality / 100% No Disclosure

We make sure that clients’ personal data remains confidential and is not exploited for any purposes beyond those related to our services. We only ask you to provide us with the information that is required to produce the paper according to your writing needs. Please note that the payment info is protected as well. Feel free to refer to the support team for more information about our payment methods. The fact that you used our service is kept secret due to the advanced security standards. So, you can be sure that no one will find out that you got a paper from our writing service.
4. ### Money Back Guarantee

If the writer doesn’t address all the questions on your assignment brief or the delivered paper appears to be off the topic, you can ask for a refund. Or, if it is applicable, you can opt in for free revision within 14-30 days, depending on your paper’s length. The revision or refund request should be sent within 14 days after delivery. The customer gets 100% money-back in case they haven't downloaded the paper. All approved refunds will be returned to the customer’s credit card or Bonus Balance in a form of store credit. Take a note that we will send an extra compensation if the customers goes with a store credit.

We have a support team working 24/7 ready to give your issue concerning the order their immediate attention. If you have any questions about the ordering process, communication with the writer, payment options, feel free to join live chat. Be sure to get a fast response. They can also give you the exact price quote, taking into account the timing, desired academic level of the paper, and the number of pages.
