Impact Subsea explores the advanced capabilities of its ISD4000 depth and temperature sensor in a new audio overview featuring Alana and Andrew, who discuss how the compact device delivers reliable subsea measurements in demanding underwater environments. Read more >>
Designed for integration into Remotely Operated Vehicles (ROVs), Autonomous Underwater Vehicles (AUVs), and other deployed systems, the ISD4000 combines precise sensing performance, robust construction, and straightforward configuration to meet the needs of scientific and industrial operations.
At the core of the ISD4000 is a temperature-compensated piezo-resistive sensing element that achieves accuracy levels of 0.01% of full scale, with an optional upgrade to 0.005% for applications requiring exceptional precision. Housed in titanium or acetal, the unit is engineered to withstand continuous exposure to pressure, shock, and vibration, providing reliable operation over extended deployments.
The podcast highlights the sensor’s versatility, with an optional integrated Attitude and Heading Reference System (AHRS) that delivers heading, pitch, and roll data along with a turns counter. This feature enhances situational awareness for vehicles conducting mapping, inspection, or positioning tasks, supporting greater consistency and mission efficiency.
Configuration is managed entirely through Impact Subsea’s seaView software, allowing all parameters to be adjusted without opening the sensor housing. This approach simplifies setup, reduces risk, and streamlines operations in the field. Combining precision, durability, and ease of integration, the ISD4000 provides a dependable sensing solution for a wide range of underwater applications.
