Underwater Thruster

MODELS

DWT6532

DWT6537

DWT1

DWTEK provides three magnetically coupling underwater thrusters. Their main feature is the absence of mechanical commutators, which naturally reduces shaft friction and inertia, and creates less noise. Also, there are no connecting shafts, which makes them easy to install and results in extremely low maintenance with high reliability.

Static seals: easy to maintain and zero failure out
Easy installation to plug in-and-out
Over-temperature protection, over-current protection, signal zero-crossing protection
Gear reducer mechanism

Sensor PCG-1000

PCG-1000 is exclusively designed for subsea inertial positioning and navigation system. The device integrates Pressure, Compass, and Gyroscope into single unit. The pressure sensor has an accuracy of 0.05%FS. It outputs Depth (meter/feet), Heading, Pitch, Roll and Turn via protocol RS232. The protocol also allows users to define sampling rates of 1Hz, 5Hz, 10Hz, 25Hz, or single shot.

Furthermore, two output formats (Binary or ASCII). Al6061 -T6 with engineering anodized treatment housing increases capability in corrosion resistance.

Integrated pressure, compass, and gyroscope
5 user-selectable measurement rate
Data directly readout in serial console
Instant plug-in & high resolution and reliability
Depth rating: 1,000m /3,000m
