Century Rayon Gat Engineer Interview Questions, Process, and Tips

RTD and thermocouples are both temperature sensors, but they work on different principles and have different characteristics.

• RTD (Resistance Temperature Detector) measures temperature by changes in electrical resistance of a metal, usually platinum.

• Thermocouples measure temperature based on the voltage produced by the junction of two different metals.

• RTDs are more accurate and stable over a wide temperature range, whil...read more

RTD sensor ranges vary depending on the type of RTD used, with common ranges being -200 to 850 degrees Celsius.

• RTD sensors can have different temperature ranges depending on the type of RTD used.

• Common RTD sensor ranges include -200 to 850 degrees Celsius.

• Platinum RTDs typically have a wider temperature range compared to other types of RTDs.

Pt 100 is commonly used in RTDs due to its high accuracy, stability, and linearity.

• Pt 100 RTDs have a resistance of 100 ohms at 0°C, making them easy to calibrate and standardize.

• Pt 100 RTDs offer high accuracy and stability over a wide temperature range.

• Pt 100 RTDs exhibit a linear relationship between resistance and temperature, simplifying temperature measurement calculations.

Transmitters are devices that convert electrical signals into electromagnetic waves for communication purposes.

• Types of transmitters include AM transmitters, FM transmitters, microwave transmitters, and satellite transmitters.

• AM transmitters are used for broadcasting audio signals over long distances.

• FM transmitters are commonly used in radio broadcasting for higher quality sound.

• Microwave transmitters are used for poi...read more
