Ultrasonic Machining (USM) also called as ultrasonic vibration machining is a machining process in which material is removed from the surface of a part by low amplitude and high frequency vibration of a tool against surface of material in the presence of abrasive particles.
Working Principle of Eductor on Ships. Eductor works on Bernoulli’s principle. It states that an increase in the speed of a fluid occurs simultaneously with a reduction in pressure. Refer to the simplified Bernoulli’s equation below for an in compressible flow. Where, v = Velocity of the fluid. p = Pressure of the fluid, and. ρ = Density .
In split range control, we will control 2 outputs with time interval. Eg :(with 4-20 ma signal, for 4-12 ma we are operating one control instrument like valve & for 12-20ma we are operating other control instrumet (other valve).

In a molecular gas laser, laser action is achieved by transitions between vibrational and rotational levels of molecules. Its construction is simple and the output of this laser is continuous.In the CO2 molecular gas laser, transition takes place between the vibrational states of Carbon dioxide molecules.
5.4.5 Engineering implications of vibration behavior The solutions listed in the preceding sections give us general guidelines for engineering a system to avoid (or create!) vibrations. Preventing a system from vibrating: Suppose that we need to stop a structure or component from vibrating e.g. to stop a tall building from swaying.
The first vibrator motor was developed in the year 1960 which are used for product massaging, but the motor development has taken a new twist in the year 1990 as users need vibration calls on their cell phones. At present, the motor designers, as well as users, have discovered from mobile phones, that mobile alerting with vibration is an outstanding technique to alert mobile operators to an .
vibration measuring instruments (contd..) • Two types of seismic transducers known as vibrometer and accelerometer are widely used. • A vibrometer or a seismometer is a device to measure the displacement of a vibrating body.

I want to know the details working principle of self generating vibration sensor which is used in gas turbine bearings or large generator. It's model number is 5485C and made by METRIX. Why it shows -10V dc when Turbine is in shutdown condition? and what is the output voltage of it in Turbine.
Potentiometric accelerometers : Relatively cheap and used where slowly varying acceleration is to be measured with a fair amount of accuracy. In these, the displacement of a spring mass system is mechanically linked to a viper arm, which moves along a potentiometric resistive element.
Working of Bourdon Gauge As the pressure is applied at the fixed end free end undergoes deformation. The free end is attached with sector which further meshes with the pinion on which pointer is mounted. Deformation of the pointer is transferred to pointer via this mechanism.
Vibrator Motor Working and Applications The first vibrator motor was developed in the year 1960 which are used for product massaging, but the motor development has taken a new twist in the year 1990 as users need vibration calls on their cell phones.
12. VIBRATION ISOLATION 12.1 Introduction High vibration levels can cause machinery failure, as well as objectionable noise levels. A common source of objectionable noise in buildings is the vibration of machines that are mounted on floors or walls. Obviously, the best place to mount a vibrating machine is on the ground floor. Unfortunately (but

vibration measurements using an accelerometer.. 3.1 Overall Vibration Values. The output of the accelerometer is an AC waveform that exactly reproduces the vibration acceleration. This waveform might be useful for an experienced vibration analyst to use for fault diagnosis but for most situations it is not appropriate or even necessary. It is much

The simplest Vibrating Screen Working Principle can be explained using the single deck screen and put it onto an inclined frame. The frame is mounted on springs. The vibration is generated from an unbalanced flywheel. A very erratic motion is developed when this wheel is rotated.
In short, vibration monitoring is a key tool for plant and equipment maintenance today. Vibration levels are measured using accelerometers, which, like most powerful engineering tools, provide excellent service as long as the engineer concerned takes a little time to appreciate how they work.
The dynamic vibration absorber is a tuned spring-mass system, which reduces or eliminates the vibration of a harmonically excited system. The working principle of the dynamic vibration absorber, as shown in Fig. 4.53A, is added to the mass spring system on the vibration objects.In order to let the amplitude of the primary system be zero, the design working frequency of the vibration absorber .
Vibration Welding of Engineering Plastics 7 2.2 Process parameters Vibration welding is generally used on large parts, yet smaller parts can be welded eco-nomically in multiple cavity tooling. A vibra-tion welded air inlet manifold is a common example of large part welding, see figure 4. The most important process parameters of
Working Principle The basic underlying working principle of an accelerometer is such as a dumped mass on a spring. When acceleration is experienced by this device, the mass gets displaced till the spring can easily move the mass, with the same rate equal to the acceleration it sensed.
Ejector Working Principle.An ejector is a device used to suck the gas or vapour from the desired vessel. An ejector is similar to an of vacuum pump or compressor. The major difference between the ejector and the vacuum pump or compressor is it had no moving parts..
How Does the Instrument Work? Before taking a vibration measurement, you need to attach a sensor that can detect vibration behavior to the machine that is being measured. Various types of vibration sensors are available, but a type called accelerometer is normally used as it offers advantages over other sensors.
