Q2. 2) What is bourdon type pressure gauge?
Ans. 
A bourdon type pressure gauge is a mechanical device used to measure pressure in a system.
• Consists of a curved tube that straightens with pressure, causing a pointer to move on a dial

• Commonly used in industrial applications for measuring pressure in pipelines, tanks, and machinery

• Available in various designs such as C-type, spiral, and helical bourdon tubes

Q3. 3) What is the liquid filled in pressure gauge?
Ans. 
The liquid filled in pressure gauge is typically glycerin or silicone oil.
• Common liquids used are glycerin and silicone oil

• The liquid helps dampen the effects of vibration and pulsation on the gauge

• It also helps lubricate the internal components of the gauge

• The choice of liquid depends on the application and operating conditions

Q4. 4) What is functioning of nucleonic type radar level transmitter and for which applications?
Ans. 
Nucleonic type radar level transmitter uses radioactive sources to measure level of liquids or solids in tanks. It is commonly used in industries like oil and gas, chemical, and power plants.
• Uses radioactive sources to emit gamma rays towards the material being measured

• The gamma rays are then reflected back to the detector, with the time taken for the reflection used to calculate the level of the material

• Suitable for m...read more

Q6. 6) Working of solenoid valve
Ans. 
A solenoid valve is an electromechanically operated valve that is commonly used to control the flow of liquids or gases.
• Solenoid valves use an electromagnetic coil to open or close the valve mechanism.

• They are commonly used in applications such as controlling water flow in irrigation systems, gas flow in HVAC systems, and fluid control in industrial processes.

• When the coil is energized, it creates a magnetic field that...read more

Q7. 7) Working of float type level measurement
Ans. 
Float type level measurement works by using a float that rises or falls with the liquid level, activating a switch or transmitter.
• Float rises or falls with the liquid level

• Float activates a switch or transmitter

• Commonly used in tanks and vessels for level control

• Examples: magnetic float level switch, displacer level transmitter

Q8. 8) Different units of pressure
Ans. 
Units of pressure include psi, bar, atm, mmHg, and Pa.
• PSI (pounds per square inch) is commonly used in the United States

• Bar is a metric unit of pressure equal to 100 kilopascals

• Atmosphere (atm) is the pressure exerted by the weight of the Earth's atmosphere

• Millimeters of mercury (mmHg) is commonly used in measuring blood pressure

• Pascal (Pa) is the SI unit of pressure
