Heavy duty underwater pan and tilts to remotely position
camera systems, acoustic equipment, RF and microwave antennas,
and other instrumentation.
The unparalleled reliability of the PT-25 heavy duty pan and
tilts is due in part to its rugged construction. Housings and
machined components are made of corrosion resistant, hard-anodized
aluminum. All external hardware is made of stainless steel, with
oceanographic and nuclear applications in mind.
The PT-25 underwater pan and tilts provide 30 lb-ft (40 N-m)
of output torque on each axis. Heavy-duty ball bearings supporting
the output shaft allow it to accommodate payloads up to 100 pounds.
The drive train for each axis of the pan and tilt uses either
a reversible synchronous motor or a brushless stepper motor coupled
to low backlash harmonic gearing. The rugged design of the gear
train allows stalling of either output shaft without damage to
the gears or the motor.
With the choice of different AC or DC power configurations the
PT-25 underwater pan and tilts can be used in a wide array of
varying environments and applications.
The PT-25 pan and tilts are available in two versions: air-filled
or oil-filled. Air-filled pan and tilts are used for shallow water
applications up to 30 meters depth. Also, air-filled pan and tilts
are suitable for above water applications where rain, humidity,
and dust are issues. Oil-filled pan and tilts are used for underwater
applications up to 3,000 and 6,000 meters depth.
The PT-25 underwater pan and tilts complement all ROS underwater
lights and underwater video
cameras and was designed to be an integral part of turnkey,
remotely operated, video inspection
systems.
