We are suppliers of B-H Curve Unit, It Consists of Electronic Circuity housed in a cabinet. One specimen of transformer stamping and another sample of ferrite ring is also supplied. This complete unit requires a C.R.O. to perform the experiment. The Unit enables one to trace the B-H loop (hysteresis) of a ferromagnetic specimen using a cathode ray oscilloscope. A measurement of the area of the loop leads to the evaluation of energy loss in the specimen. One of the specimens used in the unit is made using transformer stampings.There are two windings on the specimen (primary and secondary). The primary is fed to low A.C. voltage (50 Hz). This produces a magnetic field H in the specimen. The voltage across R1 (resistance connected in series with the primary) is proportional to the magnetic field. It is given to the horizontal input of the CRO. The A.C. magnetic field induces a voltage in the secondary coil. The voltage induced is proportional to dB/dT (B-flux density). This voltage is applied to a passive integrating circuit. The output of the integrator is proportional to B and fed to the vertical input of the CRO. As a result of the application of a voltage proportional to H to the Horizontal (input axis and a voltage proportional to B to the vertical (input) axis, the loop shown in fig. 2 is formed. The transformer Fig.3 core may be replaced by a ferrite ring supplied with the instrument.

Working Principle
The principle used in the measurement of velocity (ν) is based on the accurate determination of the wavelength (λ) in the medium. Ultrasonic waves of known frequency (f) are produced by a quartz crystal fixed at the bottom of the cell. These waves are reflected by a movable metallic plate kept parallel to the quartz crystal. If the separation between these two plates is exactly a whole multiple of the sound wavelength, standing waves are formed in the medium. This acoustic resonance gives rise to an electrical reaction on the generator driving the quartz crystal and the anode current of the generator becomes a maximum. If the distance is now increased or decreased, and the variation is exactly one-half wavelength (λ /2), or multiple of it, anode current becomes maximum. From the knowledge of wavelength ( λ ) the velocity (v) can be obtained by the relation: Velocity = Wavelength x Frequency v = λ x f The Ultrasonic Interferometer consists of the following parts:

Optional: If the variation in the velocity with temperature is to be studied, water at various desired constant temperatures is made to circulate through the double walled jacket of the cell with external circulating water bath. A number of parameters related to ultrasonic velocity are:

• Comprehensibility
• Effective Debye Temperature
• Excess Enthalpy
• Hydrogen Bonding
• Intermolecular Free Length
• Salvation Number/ Hydration Number
• Vander Wall's Constant
• Rao's Constant
• Wada Constant
• Molecular Interaction
• Proton Relaxation Rate
• Relative Association
• Relaxation Time and Relaxation Strength
• Acoustic Impedance
• Stacking Constant
• Space Filling Factor
• Cohesive Energy Barrier
• Latent Heat Of Vaporization
• Specific Heat Ratio
• Miscibility and Compatibility of Blends and many more

The Air Permeability tester for textiles is used for air permeability testing of the fabrics. Digital and analogue models are available. This system consists of an arrangement for holding the test specimens between two flat faces so as to expose a known area to the flow of air through it, a vacuum system to draw air through the exposed area of the test specimens. There is an arrangement to measure the volume of air flowing through the test specimen, and arrangement to measure the pressure drop between the faces of the test specimen. The test specimen is hold between two round-shaped grips. The grips are lined with rubber gasket to avoid the leakage of air through the edges. The two grips can be held the test specimens with the help of a hand operated screw mechanism. The vacuum needed to draw the air through the test specimens is created with the vacuum pump supplied with the instrument. The vacuum pressure is measured by the digital manometer (or manometer tube) in terms of mm of water level & airflow is measured by the Rotameters attached with the instrument. The equipment is metallic paint & bright chrome plating finish for corrosion resistant finishing.

Specification:

• IS: 11056- 1984: Method for determination of air permeability of fabrics
• DIN 53887: Testing of fabrics determination & the air permeability of fabrics.
