A Rope Brake Dynamometer is a mechanical device used to measure the brake power of an engine by utilizing frictional resistance created by a rope wound around a rotating drum. It is commonly used for testing the power output of engines, particularly in laboratories and workshops.
Measurement & Instrumentation
Prony Brake Dynamometer: Definition, Working, Construction, Derivation, Diagram, Advantages, Applications & Disadvantages
A Prony Brake Dynamometer is a simple mechanical device used to measure the power output of an engine or motor by absorbing energy through friction. It is one of the oldest types of dynamometers and operates by applying friction to a rotating shaft and measuring the resulting force.
Inclined Manometer: Definition, Working, Construction, Derivation, Diagram, Advantages, Applications & Disadvantages
An inclined manometer is a device used to measure small pressure differences with greater accuracy. It consists of an inclined tube filled with a liquid, allowing for more precise readings compared to a standard U-tube manometer.
U Tube Manometer: Definition, Working, Construction, Derivation, Diagram, Advantages, Applications & Disadvantages
A U-tube manometer is a device used for measuring pressure differences in fluids. It consists of a U-shaped tube filled with a liquid (usually mercury or water) and is used in applications requiring accurate pressure measurements.
Pneumatic Load Cell: Definition, Working, Construction, Diagram, Advantages, Applications & Disadvantages
A pneumatic load cell is a force-measuring device that uses compressed air or gas pressure to determine the applied load. It operates based on the principle of balancing an applied force using air pressure and is commonly used in precision weighing applications where high accuracy and environmental resistance are required.
Hydraulic Load Cell: Definition, Working, Construction, Diagram, Advantages, Applications & Disadvantages
A hydraulic load cell is a force-measuring device that uses hydraulic pressure to determine the applied load. It operates based on Pascal’s principle, where an external force applied to a fluid-filled chamber results in a pressure change that can be measured using a pressure gauge. Hydraulic load cells are commonly used in industrial applications requiring precise force measurement.
Strain Gauge Load Cell: Definition, Working, Construction, Types, Diagram, Advantages, Applications & Disadvantages
A strain gauge load cell is a force-measuring device that converts mechanical force into an electrical signal. It operates based on the principle of strain measurement, where an applied force deforms a structure, and the strain gauge sensors detect the change in resistance, providing an accurate weight or force measurement.
Bellows Pressure Gauge: Definition, Working, Parts, Diagram, Advantages, Applications & Disadvantages
A Bellows Pressure Gauge is a mechanical device used to measure pressure in fluid systems. It operates on the principle of expansion and contraction of bellows (a flexible, accordion-like component) when exposed to pressure variations. This movement is converted into a readable measurement using a mechanical linkage and pointer.
Dial Gauge: Definition, Working, Parts, Diagram, Advantages, Types, Least Count, Applications & Disadvantages
A dial gauge, also known as a dial indicator, is a precision measuring instrument used to measure small linear distances with high accuracy. It is widely used in mechanical engineering and manufacturing for measuring flatness, alignment, and deflections in machine components.
Tomlinson Surface Meter: Definition, Working Principle, Parts, Diagram, Advantages, Applications & Disadvantages
A Tomlinson Surface Meter is a mechanical instrument used to measure the surface roughness of a material. It operates by tracing the profile of the surface with a stylus and amplifying the vertical displacement, which is then recorded as a trace on smoked glass.
This instrument is widely used in metrology and quality control to ensure that manufactured components meet required surface finish standards.
