Description
The ISD4000 is a compact, survey grade Depth & Temperature Sensor.
Optionally, the unit can also be provided with an integrated Attitude and Heading Reference System (AHRS). This provides highly stable Heading, Pitch and Roll readings.
Depth
A temperature compensated piezo-resistive pressure sensor is used to determine Depth to 0.01% Full Scale accuracy. Optional 0.005% FS
Available in a variety of pressure ranges (10, 30, 50, 100, 300, 400 & 600 Bar) ensures that the highest level of accuracy can be achieved for any depth of application.
Depth can be provided at any rate up to 100 Hz – ideal for precision control and monitoring applications.
Temperature
A Resistance Temperature Detector (RTD) probe provides temperature to 0.1°C Temperature Accuracy, Optional 0.01°C
The RTD is located directly inside the temperature probe, placing it exceptionally close to the water. This enables a very high accuracy temperature reading to be obtained, with exceptionally low latency.
Attitude & Heading Reference System (AHRS)
Optionally available on the ISD4000 is an integrated Attitude & Heading Reference System (AHRS) providing Heading, Pitch & Roll. The AHRS is based on Micro-Electrical-Mechanical-System (MEMS) technology. Within the ISD4000 there are three MEMS based Gyros, Accelerometers & Magnetometers. The outputs from each of these MEMS devices are fused together, providing highly stable Heading, Pitch & Roll. The Heading is highly resilient against temporary magnetic interferes. This is aided by a soft and hard iron calibration feature once the unit has been installed on the ROV, AUV or other underwater system.
