Introducing the ISD4000
A temperature compensated piezo-resistive pressure sensor is used to determine Depth to 0.01% Full Scale accuracy.
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.
The ISA500 utilises sonar technology to derive distance measurement.
Operating by default at 500kHz, the unit utilises a broadband composite transducer and electronics together with an advanced digital acoustic engine. The combination of these enable the unit to achieve long range and high accuracy.
The unit can be operated at any frequency from 400 to 600kHz – ideal for different applications or operating in conjunction with other hydro-acoustic or sonar equipment.
A Resistance Temperature Detector (RTD) probe provides temperature to 0.01 degrees C accuracy.
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
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.
