PTW-9500 Portable Tetheredsonde
The Model PTW-9500 Portable Tetheredsonde Winch is designed to support and control tethered balloon-borne meteorological sensors. In addition to a constant tension mode, full remote control of the powerful variable speed motor permits users to precisely control the altitude and tension of a tethered balloon radiosonde. The ATW-9500 is essentially a portable computer-controlled electronic cable winch specifically optimized for the precise control of vertically-lifted balloon payloads. As the system operates, motor current and speed is measured by the internal CPU to govern safe and proper cable payout rates.

General DescriptionThe Model PTW-9500 Portable Tetheredsonde Winch is designed to support tethered balloon-borne meteorological sensors. Full remote control of the powerful variable speed motor provides precise control over the altitude and tension of a tethered balloon radiosonde (tetheredsonde). Principle of OperationThe PTW-9500 is a portable remote controlled electronic cable winch specifically optimized for the precise control of vertically-lifted balloon payloads such as tetheredsondes. As the system operates, motor speed is controlled by the user and a handheld RF-linked remote control to govern safe cable payout rates under various wind conditions. Tetheredsondes replace the need for temporary meteorological towers and provide instant vertical wind profiles. Depending on wind conditions and loads, tethered sensors such as the YES Refrensonde can be raised & lowered throughout the boundary layer up to altitudes approaching 6500 feet (≈2000 meters). The system consists of a sturdy reel mounted in an aluminum chassis, coupled to an internal variable speed DC gear motor drive. Line payout is controlled by an anti-tangle mechanism similar to those used on large fishing reels. A durable waterproof high impact plastic case protects the system and permits rapid setup. Reel speed and direction are governed by a battery-powered handheld wireless remote control unit. Features
