Temperature Measurement and Control devices interview QA

Dear Students,

Are you Preparing for Interview ?

Taking a Quiz may be the quickest and easiest way to prepare yourself for your Interview.

With this Quiz we are making it simple to absorb new information as you go, and you might find that it saves you some time( No need to refer a variety of books and Websites in order to cover the ocean of topics).

With series of practice tests containing Multiple Choice Questions Quiz, this Quiz will build your confidence by providing tips and trick to solve questions ( Answer with explanation where required).

*************What You Will Learn****************************

The need for more consistent and accurate ways for temperature measurement & Control led to the invention of temperature-measuring devices, or sensors.

In industrial environments, high process temperatures, pressures, and vibration make it necessary to have a robust temperature sensor. Fast response time, accuracy, and stability are also needed. While several types of temperature sensors are available, the two most commonly used in the process measurement industry are resistance temperature detectors (RTDs) and thermocouples (T/Cs).

You will learn about the principles on which RTDs and T/Cs operate and how they are constructed. You will also learn about additional apparatus needed to protect sensors and to transmit their signals to process control systems.

The following topics are included in this practice test:

Importance of Temperature measurement & Control?

Temperature Measurement Scales

• Fahrenheit

• Celsius

• Absolute (Kelvin and Rankine)

Temperature Sensors

• Resistance temperature Detector (RTD)

• Thermocouple (T/C)

• Selection criteria

Thermowells

• Materials of construction

• Mounting methods

• Stem designs

• Selection criteria

• Thermowell failure reasons & How to prevent

The Temperature Sensor Signal transmission to Control system i.e. DCS/ PLC

For control, safety, or monitoring purposes, a temperature measurement signal must be transmitted from the point of measurement to the DCS of the process.

• Benefits of using a temperature transmitter

• Potential drawbacks of using wiring direct

• How input/output (I/O) cards work both with transmitters and with wiring direct.
