ISA500-L

Impact Subsea is proud to present the ground breaking ISA500-L. A highly robust underwater Altitude/Range measurement sensor.

Based on the ISA500 platform the ISA500-L utilizes a broadband composite transducer together with an advanced digital acoustic engine to provide the highest level of stability and range available from a 500kHz Altimeter.

For applications where purely underwater Altitude/Range measurement is required the ISA500-L is the unit of choice.

120 meter range capability, weighing only 0.325kg in fresh water, and using only 51mA of current at 24VDC; makes the ISA500-L a highly compact and efficient long range Altimeter.

The ISA500-L is provided in a robust titanium housing. Alternative OEM configurations are available upon request.
