You evaluate a number of different temperature measuring devices in your laboratory classes.
a. Explain how at least three operated and justify why you would choose those devises for the scenario below.
‘A local company requires measuring devices to measure temperature in various situations they could use for measuring temperature in the air conditioned Offices, the foundry where they melt non ferrous materials for molding, and the outside temperature at the outlet of the heat vents located on the foundry roof’.

can you please provide some bullet point
We don't know what temperature measuring devices you evaluated.
thanks for the reply.
we evaluated
*Glass and mercury thermometers
*PROBE THERMOMETERS
*Electronic ear thermometer
*Dual Sensor Thermometer
the purpose of this laboratory class was to only understand different types in terms of contact and non-contact thermometer and a little overview of which might be accurate.
the laboratory class wasn't much too useful and we were told to do our own research on the types of measuring devices.
Sure! Here are three temperature measuring devices that could be suitable for the scenario you provided, along with explanations of how they operate and why they would be appropriate for the different situations:
1. Thermocouples:
- Thermocouples consist of two different types of metal wires joined together at one end. When there is a temperature difference between the joined end and the free ends of the wires, it generates an electrical voltage.
- Thermocouples are durable and can measure a wide range of temperatures, making them suitable for the foundry where high temperatures are involved.
- They are also relatively inexpensive, making them a good choice for a company looking for a cost-effective solution.
- However, thermocouples may require calibration to ensure accuracy, and their small voltage signal may require amplification or special equipment for measurement.
2. Resistance Temperature Detectors (RTDs):
- RTDs are temperature sensors that operate on the principle that electrical resistance changes with temperature.
- RTDs typically use pure platinum as the sensing element due to its stability and linearity.
- They offer high accuracy and stability, making them suitable for temperature measurements in air-conditioned offices where precision and reliability are important.
- RTDs also have a wide temperature range capability, ensuring they can measure hot air coming from the heat vents on the foundry roof.
- However, RTDs can be more expensive compared to other options, and they may require additional signal conditioning to obtain accurate temperature readings.
3. Infrared Thermometers:
- Infrared (IR) thermometers measure temperature by detecting the thermal radiation emitted by an object.
- They are non-contact devices that measure the temperature of a surface without physically touching it.
- Infrared thermometers provide quick and easy measurements, making them suitable for measuring the outside temperature at the outlet of the heat vents on the foundry roof.
- They can also be used to measure temperatures in air-conditioned offices without disturbing the environment.
- However, it's worth noting that IR thermometers may not provide accurate readings for shiny or reflective surfaces, and their accuracy may be affected by distance and other factors.
By using a combination of thermocouples, RTDs, and infrared thermometers, the local company can effectively measure temperature in various situations. However, before making a final selection, it may be prudent to consider other factors such as budget constraints, calibration requirements, and the level of accuracy needed for each specific measurement scenario.
