3.0 System Components
3.1 Probe
The ISA500 probe is the core sensor used in the ISFMD system. The
ISA500 is a hydro-acoustic device, which transmits pulses of sound
and detects corresponding returning echoes.
The probe operates at an acoustic frequency of 500kHz. The probe
utilises a broadband composite transducer and electronics
together with an advanced digital acoustic engine. The
combination of these enable the probe to achieve a high level of
sensitivity, making it an ideal FMD sensor probe.
3.2 Probe Protective Holder
A robust acetal holder, complete with stainless steel (316) 'T-
Bar', is provided for the ISA500 probe to protect the connector
and cable.
The holder also allows the unit to be held securely by a diver or
ROV manipulator during operation.
3.3 Cable Reel
A 100 or 200 meter length of cable is supplied on a reel.
Subsea, the cable is terminated with a Subconn connector for quick
connection to the ISA500 probe.
Topside the cable is terminated with a Souriau connector for quick
connection to the topside interface box.
