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
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
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...
Final control elements are classified based on their action, type of motion, and type of signal.
Based on action: On-off control, proportional control, PID control
Based on type of motion: Linear motion, rotary motion
Based on type of signal: Pneumatic, hydraulic, electric
Examples: Control valves, actuators, solenoid valves
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...
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
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
Transducers can be classified based on various criteria such as principle of operation, electrical output, and application.
Classification based on principle of operation: resistive, capacitive, inductive, piezoelectric
Classification based on electrical output: analog, digital
Classification based on application: temperature, pressure, level, flow
Other classifications: active vs. passive, contact vs. non-contact
