Britannia Interview Questions and Answers

Level measurement is the process of determining the height of a substance in a container. Radar and ultrasonic are two common methods used for this purpose.

• Level measurement is important in industries such as oil and gas, chemical, and food processing.

• Radar level measurement uses electromagnetic waves to determine the level of a substance in a container.

• Ultrasonic level measurement uses sound waves to determine the level of a substance in a container.

• Both methods are non-cont...read more

A transmitter is an electronic device that converts electrical signals into radio waves for transmission.

• Transmitter is used to send information over long distances.

• It converts electrical signals into radio waves.

• Transmitter consists of an oscillator, modulator, and amplifier.

• The oscillator generates a carrier wave, which is then modulated with the information signal.

• The modulated signal is then amplified and transmitted through an antenna.

• Examples of transmitters include rad...read more

A temperature gauge is a device used to measure and display the temperature of a system or environment.

• Temperature gauges are commonly used in various industries such as automotive, HVAC, and manufacturing.

• They can be analog or digital, providing a visual representation of temperature.

• Some temperature gauges are designed for specific applications, such as oven thermometers or refrigerator thermometers.

• They can measure temperature in different units, such as Celsius, Fahrenhei...read more

A pressure gauge is a device used to measure the pressure of a fluid or gas in a container or pipeline.

• It consists of a dial with a needle that indicates the pressure reading.

• There are different types of pressure gauges such as Bourdon tube, diaphragm, and capsule gauges.

• They are commonly used in industries such as oil and gas, manufacturing, and automotive.

• Pressure gauges are also used in medical equipment to measure blood pressure.

• Regular calibration is necessary to ensure ...read more

Capacitor stores electrical energy while varistor protects against voltage surges.

• Capacitor stores energy in an electric field while varistor is a voltage-dependent resistor.

• Capacitor is used in filters, tuning circuits, and energy storage while varistor is used in surge protection.

• Capacitor has two conductive plates separated by a dielectric while varistor has a ceramic or metal oxide material.

• Capacitor is polarized while varistor is non-polarized.

• Examples of capacitors incl...read more

A potentiometer is an electronic component that can vary the resistance in a circuit.

• It is commonly used to control the volume in audio equipment.

• It can also be used to adjust the brightness of a light or the speed of a motor.

• Potentiometers come in different types, including linear and logarithmic.

• They are often represented in circuit diagrams with the symbol of a resistor with an arrow pointing towards a wiper.

• Potentiometers can be single-turn or multi-turn, depending on the...read more
