What is a dynamometer definition?
Definition of dynamometer 1 : an instrument for measuring mechanical force. 2 : an apparatus for measuring mechanical power (as of an engine)
What is dynamometer and its type?
A dynamometer is a device used for measuring the torque and brake power required to operate a driven machine. Dynamometers can be broadly classified into two types. They are: Power Absorption Dynamometers: Power Absorption dynamometers measure and absorb the power output of the engine to which they are coupled.
What is basic principle of dynamometer?
In an engine dynamometer, water flow, proportional to the desired applied load, creates resistance to the engine. A controlled water flow through the inlet manifold is directed at the center of the rotor in each absorption section. This water is then expelled to the outer dynamometer body by centrifugal force.
Where are dynamometers used?
Dynamometers are commonly referred to as a dynameter or dyno. They are used to measure power, output, force, and torque. A force is applied to the flexible metallic ring of the dynamometer, it bends, and the applied force is measured. They are used in a variety of industries from laboratory science to manufacturing.
What is another name for dynamometer?
In this page you can discover 5 synonyms, antonyms, idiomatic expressions, and related words for dynamometer, like: ergometer, dyno, drive-train, and null.
What are the different types of dynamometers?
There are two main types of dynamometers, which are both used frequently in the auto industry and in industrial and manufacturing processes. These are chassis dynamometers and engine dynamometers. Chassis dynos measure automobile wheel rotation with computer software in order to determine engine or motor torque.
What are the various types of dynamometer?
What are the advantages of dynamometer type instruments?
Advantages of Dynamometer type instrument:
- As the instrument has Square Law response so can be used on both the dc as well as on AC.
- These instruments are free from hysteresis and Eddy current errors.
- Ammeter up to 10A and voltmeter up to 600V can be constructed with precision grade accuracy.
What is a dynamometer made of?
It is made up of brake blocks that press against a rotating wheel attached to the motor. The braking blocks create friction force to slow the velocity of the wheel. The purpose of a Prony brake dynamometer is to measure braking power.
What are the different types of brakes and dynamometers?
Prony brake dynamometer, and 2. Rope brake dynamometer.
Which dynamometer type has uniform scale?
Wattmeter
Dynamometer instrument can be used as Ammeter, Voltmeter, and Wattmeter. But it is more effective in the Wattmeter type because power is proportional to the square of the current. The scale is uniform in the Wattmeter type.
How many coils are there in dynamometer type wattmeter?
two fixed coils
Electrodynamometer instrument has two fixed coils and one moving coil. For using this instrument as a wattmeter to measure the power, the fixed coils acts as a current coil and must be connected in series with a load.
