Temperature 2 °C to 35 °C; pre soak tank available for conditioning transducers or materials before testing (test medium: fresh water)
Cable Specifications cables for devices under test may be packed using existing packing glands (for pressures under 1000 psi); select Brantner SeaCon bulkhead connectors are also available; special flanges may be machined to meet special customer cabling requirements; typically, 10 meters of cabling within the tank and 10 meters topside are required
Accommodations large floor area allows substantial space to set up special peripheral equipment
Type of Operation discrete pulsed sinusoid frequency and arbitrary waveform acoustic measurement system; polar directivity patterns, transmit and receive
Frequency Range 1 kHz to 1 MHz (lower frequencies available via special methodologies)
