Operation of the CSP-S with a boomer sound source.
The CSP-S has a 300J Limit switch which must be engaged when operating with a
boomer sound source to prevent accidental damage. The CSP-S should only be
operated on POWER Level 1 HI, MED and LOW for boomer acquisition.
A boomer plate as a sound source produces a single pulse and the amplitude and
duration of this pulse is controlled by the energy going into it. The energy is derived from
the voltage and the quantity of energy stored in the CSP unit. Traditionally, boomers
have operated from around 3500 to 3800 volts. However a feature of the AA200 and
AA300 boomer plates is that they will produce a longer pulse (and hence more
penetration) with a lower voltage and higher capacitance from the energy source (CSP-
S). The LO voltage setting achieves this so, for example, using an AA300 boomer plate
at 200J at 3 pulses per second may be a common way of using the transducer with the
traditional 3.5 kV supply voltage.
Load Specifications:
The CSP-S units are designed to deliver high currents into boomer or sparker type loads.
The loads are quite different in make-up.
Boomer Load
A boomer plate consists of a coil imbedded in an epoxy or plastic material and thus by its
nature is an inductive load. The inductive ‘kickback’ is controlled by circuitry inside the
CSP. Typical currents into a boomer plate are listed below:-
Energy AA200 Plate EG+G Uniboom
300J 1250A 1350A
The currents will vary according to the length and type of cable used between the load
and the energy source. Note that the CSP-S units are specified for AAE and EG+G
boomer plates and have not
– to date- been tested with any other type.
Ensure that the energy and repetition rate do not over drive the sound source ! (boomer
plate - check the boomer plate manual).
