1/2

DESCRIPTION:

The low level signal output of electrical transducers are

need to be amplified before further processing. This is

done by the use of instrumentation amplifier. The

thermocouple transducer output is connected as a

input of instrumentation amplifier, Which is directly

amplify the low level signal output of transducer to a

fixed amplification. This output is terminated on the

front panel.

FEATURES:

Experiment to study the instrumentation amplifiercharacteristics by using thermocouple input transducer.

Low and high values of input and gain Resistor sets are provided to connect different Amplifying outputs. Thermocouple sensor is be provided as a Input transducer of

Instrumentation amplifier.

It can compatible to connect any form of resistive transducer in a bridge circuit All the components are mounted separately on the front panel. Inter connection cords and technical reference manual are provided.

DESCRIPTION:

This trainer is designed to find out the iron loss and

permeability of a given ring specimen using Maxwells

Bridge. The specimen is connected in one arm and the

effective resistance and effective capacitance of the arm is

calculated and the iron loss is found out. The AC

permeability can be found out by finding the inductance of

specimen through experiment and from the physical

constances.

FEATURES:

Excellent observation of Hystersis loop in CROpossible

Possible to measure Hystersis loss and Eddy current loss and finally, the iron loss of the givenring specimen.

Verification of theoretical & practical valve matching is possible Provided with student patchable front panel & circuit diagram Enclosed in a fine finished metal cabinet, detailed experiment with sample calculations are

provided
