The following studies can be carried out with the set- up:
1. study of Dielectric constant in solids
Experiment:
Dielectric constant in solids
probes Arrangement
it has two individually spring loaded probes.
The probes arrangement is a suitable stand , which also holds the sample plate. To ensure
the correct measurement of sample temperature the RTD is embedded in the sample plate just
just below the sample . this stand also serves as the lid of temperature controlled oven. proper leads are provides for provided for connection to capacitance meter and Temperature controllr.
SAMPLE:
Barium Titanate (BaTiO3)
OVEN
This is a high quality temperature controlled oven. The oven has been designed for fast
heating and cooling rates, which enhances the effectiveness of the controller.
MAIN UNITS
The set-up consists of two units housed in the same cabinet.
a)over Controller
platinum RTD (A CLASS) has been used for sensing the temperature. A Wheatshone bridge
and an instrumentation amplifier are used signle conditioning. Feedback circuit ensure offset and linearity trimming and a fast accurate control of the oven temperature.
B.) Specifications of the oven
C.) This a compact direct instrument for the measurement of capacitance of the sample.
