Rudder or propeller angular position transmitter KINAX WT720

Transcription

1 Description The is a robust, absolute angular position transmitter, which is particularly suitable for use in marine applications such as the detection of rudder or propeller positions. In contrast to potentiometers, the Camille Bauer rotary encoder uses a unique, non-contact and maintenance-free capacitive measuring principle. This technology ensures optimal performance and a long life of the devices. The high mechanical strength, the robust design, the easy assembly and commissioning, the free parameter assignment and the GL approval guarantee the highest quality, flexibility and reliability in the application, installation and maintenance. GL approved Ex approved Features Suitable for detecting rudder or propeller positions Thanks to the robust mechanical design and the high protection class IP67 / IP69K, it is ideally suited for use on board of any ship No wear and maintenance thanks to contactless capacitive measuring principle Easy on-site parameterization via push buttons (zero point and min./ max. setting and clockwise / counterclockwise) Angle ranges freely selectable (e.g., ±180, ±38, ±5 ) ma analog output / 2-wire connection technology Continuous shaft rotation (rotatable) Easy and fast assembly and commissioning Various approvals such as the ship's suitability according to GL and the explosion protection according to ATEX and IECEx Customer benefits Ensuring long life without loss of performance Cost savings thanks to simple assembly, commissioning and parameterization High operational reliability thanks to capacitive measuring principle, use of high-quality materials and external approvals No maintenance as there is no wear Easy integration into designs and applications Application Measures and transmits the angular position of the rudder or propeller position of ships Technical data General Transmitter type: Measured quantity: Measuring principle: Measuring input Angle measuring range: Analogue 2-wire...20 ma Angle of rotation Capacitive method Free Programmable between: ±180, ±38, ±5, etc. Drive shaft: Ø 10 mm [0.39"] Ø 19 mm [0.78"] with flange adapter Starting torque: Sense of rotation: Measuring output Standard range: Max.

6 Electrical connections The electrical wires are connected to the transmitter via an M12 x 1 / -pole plug connector (only in the non-ex variant) or an M16 x 1.5 cable gland. The cable gland version is connected according to the connection diagram via a spring-type push terminal. The Ex variant may only be used with the threaded cable connection supplied. Permissible cable-ø: NEx 6-10 mm Ex -8 mm max. conductor cross-section: 2,5 mm 2 Connection allocation spring-type terminal block Connection allocation plug (only for non Ex version) 2 V DC R ext ma Pin Plug not connected Programming Parameters may be set by keys and DIP switches right at the device. The center position can be set to 50% (12mA), min. Angular position 0% (ma) and max. Angle position 100% (20mA), as well as the direction of rotation independent of each other. This greatly facilitates the adjustment during commissioning. For an order with a measuring range parameterized by the manufacturer (for example, ± 5 ) the center position 50% (12mA) can be set by means of push buttons. The defined measuring span (for example, ± 5 ) is maintained. The factory setting can always be restored in case of maloperation.
