High Voltage Testing
For
high power transducers, amplified load and transducer efficiency
are all important. The Piezotest HV DiMeter Systems provides a direct
means of testing capacitance and dielectric loss over a wide range
of electrical fields. The system is capable of delivering from 100
V to 3500 V into a wide range of capacitive or resistive loads.
The test frequency range is from 300Hz to 3kHz. Good accuracy is
provided on samples from 100pF to 3000pF.

All
systems include a safety enclosure and clamping unit, which grips
the sample under test and provides shielding to protect the user
and prevent undesirable RF emissions in the event of arcing. A full
interlock mechanism exists, making it impossible to access the test
electrodes while the power is applied. An all-round polycarbonate
shield protects against debris which may be produced when a sample
shatters due to overheating.

PC or Stand-alone Operation
As with
most Piezotest instrumentation products, the HV DiMeter system includes
a microprocessor subsystem. This offers the ability to provide a printout
of measurements, when used with a standard computer printer. A statistical
analysis of a set of data - such as a batch of elements - may be carried
out. There is also a facility to store up to one hundred measurements
for a later recall and analysis.
Use of
digital signal processor (DSP) technology yields rapid response times
for all readings, as well as improved reliability and rapid calibration
and setup procedures.
The unit
may be interfaced to a computer system for further processing of results.
This is achieved using a RS-232C communications link, present on almost
all computers. A simple command set used via this link gives complete
remote control of the HV DiMeter, including the setting of the measurement
range and test frequency.
