Detailed description
Detailed description
Designed for rigging on large vessels, the CYCLOPS Smarttune² 1" is a wireless load sensor turnbuckle that replaces existing turnbuckles. It provides real-time load data essential for optimizing headsail shape, rig balance, and achieving repeatable settings. Its design allows for easy retrofit installation without complex modifications or dismasting.
Measurement and Accuracy
With a 1-inch thread size, the Smarttune² 1" is suited for high-load applications on monohulls and multihulls up to 60 feet. It offers a maximum working load (MWL) of 12 tonnes (12 000 kg) and a nominal breaking load (NBL) of 22 tonnes (22 000 kg). Measurement accuracy is ±1% of MWL within a temperature range of 0 to 40°C. The sensor provides data for fatigue monitoring and load cycle history analysis, enabling rigging lifespan assessment.
Connectivity and Integration
The CYCLOPS Smarttune² 1" wirelessly connects to a smartphone via the Smartfittings app using Bluetooth technology. It is also compatible with marine electronics systems such as Vakaros Atlas 2 and Sailmon MAX (directly, without a gateway) or other systems via an optional Cyclops gateway, enabling live data streaming and recording. The Smartfittings app displays live loads, records data for post-sail analysis, adjusts data frequency (up to 10Hz), and manages sensor status. The optional gateway outputs data via NMEA2000, NMEA0183, NKE, UDP, and MQTT, and can handle up to 50 sensors with IP54 waterproofing.
Design and Durability
The sensor measures 400 x 68 x 40 mm and weighs 1.9 kg. Its housing is rated IP68 for water resistance, ensuring durability in marine environments. It is constructed from 316L stainless steel body with brass threaded inserts and an Acetal housing. The Smarttune² 1" is powered by internal rechargeable batteries, offering up to 8 000 hours of battery life in extended mode and 2 000 hours in active mode. Charging is wireless via a Cyclops charging base.
