Description
This probe system is built around a Dukane 2220HN4-VL1 2200 watt 20kHz DPC I generator built in about 2008. This generator is designed to be mounted in an electrical cabinet hanging from the panel, preferably with a window so the front panel of the unit can be viewed without opening the door and with access to relatively cool air. It could be mounted hanging from some sort of structure ( or if feet were attached lying on its side) outside an electrical cabinet but the power connection is by a terminal block on the bottom of the unit (near the grounding lug in the photo) and protecting the wiring and/or protecting personnel from the wiring would need to be taken into account. Manual is still available for download from Dukane and we will email a copy to you if you are contemplating how to mount this generator. This generator has a microprocessor-based driver with linear ramp soft start and Auto-Trac fully automatic tuning. The driver also uses feedback from the transducer ceramics to match actual amplitude to desired amplitude, so amplitude does not vary either with line voltage in nor with acoustic load. This makes the generator much more efficient so the power electronics run cooler. The high power input module and DC buss as well as the matching module are analog and mounted on heat sinks that protrude into a cooling tunnel with a thermostatically-operated fan, so plant air is only drawn into the tunnel when required and only the heat sinks are in contact with air in the tunnel which reduces dust-blanket effect on circuit board components to a significant degree. This generator is equipped with current loop amplitude control and will be shipped with JU716 jumpered on the circuit board behind the front panel door which disables this feature. To reenable the feature move the jumper to JU715, but if current is not then applied to control the amplitude there will be no amplitude (see manual). The history of this generator is not known but it is in good condition inside and out and had an inspection and input module replacement done in Dukane’s repair department prior to being offered for sale here. Warranty is 30-day money back or exchange in the USA, no return or refund on international sale.
This generator is matched to a new tributek AM30122C 3000W transducer (replaces Dukane 41C30) with three year limited warranty (or 2,080 ultrasound hours, whichever is less).
New BT30250 titanium booster by tributek with 3.25″ ring (specify gain ratio) 1/2-20 input and output threads, one year warranty.
New CSHV03M ultrasound cable SHV/SHV by tributek, 3 meters, one year warranty.
Power cable is not included for obvious reasons.
System start cable not included. Generator runs ultrasound when pin 2 and pin 8 receive dry contact closure on SYSTEM INPUTS/OUTPUTS connector on front panel (HD15 15-pin subminiature as on VGA cable). It is suggested this contact closure be hold relay style so ultrasound shuts off if control voltage is lost (as in emergency stop).
All above made in USA.
One system available, subject to prior sale.
