THRU-HULL MOUNT • Speed • Temperature
S650, ST650
With Self-Closing Valve
U.S. Patent No.: 4,898,029; 5,186,050
Canadian Patent No. 1,313,775
Australian Patent No. 605,281
SECTION 1
Introduction
Japanese Patent No. 1851014
The S650/ST650 sensor incorporates a patented self-closing valve
which minimizes the flow of water into the boat when the speed/
temperature insert is removed. This allows routine paddlewheel
cleaning without getting wet. Fins straighten water flow onto paddlewheel and improve flow stability and accuracy at low speeds.
Because of the high degree of tooling, the ST650 is priced comparably with standard paddlewheel sensors.
The S/ST650 paddlewheel and valve assembly can be retrofitted
into Airmar speed/temperature series: S/ST100, S/ST500, and
S/ST550. Boaters can upgrade to a self-closing S/ST650 without
changing their thru-hull fitting or hauling the vessel. Consult Airmar for the part number of the correct retrofit kit for your needs.
The S650 and ST650 are available in low profile and flush mount
styles.
Self- closing valve eliminates “gusher” when speed/temperature
insert is removed

Specifications
Paddlewheel has four asymmetrical, hydrodynamic blades
•
•
Hall-effect magnetic sensor for high-level pulse output
•
Unitary bearing inside the paddlewheel hub assures exact
alignment and minimal rotational friction
•
Polished paddlewheel shaft for quick start up
Dual O-rings for superior sealing
•
•
Reverse polarity protection
Shielded cable to minimize noise pick-up and emission
•
Designed to meet CE requirements
•
•
Arrow and notch on housing facilitates installation
Alignment key for easy speed/temperature assembly
•
removal and insertion in difficult access locations
Installation requires 51mm (2") diameter hole
•
Rubber washer allows tightening hull nut
•
to irregular surfaces.
•
Blanking plug included
•
Standard cable length: 9 m (30')
Fins straighten water flow onto paddlewheel increasing flow stability and accuracy. Particularly effective
when a cross flow is present.
Applications
Plastic not for use in wood hulls
•
•
Bronze for fiberglass or wood hulls only
