Digital Loadcell Amplifier
The Digital Loadcell Amplifier converts standard load cells or load pins into RS232, NMEA 0183, CANbus (NMEA 2000 ready), Bluetooth option or 0-5V analogue data. It also has a trip relay for use as an alarm output or limit switch. The DLA1 can be connected directly to our Stowe Dataline GX display and Loadpin to work as a standalone system, with user friendly calibration and alarm settings carried out entirely from the display buttons. Alternatively the DLA1 can also be calibrated from a PC connected via RS232 or via a push button and adjustment inside the top cover. The DLA1 has two RS232/NMEA inputs and can be programmed to multiplex these inputs to combine data with the measured load before re-transmitting it via any one of the outputs. The output of the DLA1 can be logged using a PC running Expedition software. The DLA1 offers fantastic accuracy, stability and noise immunity.
The A+T DLA2 Loadcell module is an element of a new A+T Instruments processor system. It also provides a direct replacement for the now discontinued B&G Fastnet Loadcell Amplifier and it will provide an additional configurable linear channel input.
Paddlewheel to B&G Underwater Unit Converter
Converts new style paddlewheel boat speed sensor signals to old style B&G UWU signals. NMEA output also available as an option, providing a standalone unit with built in calibration and NMEA output to interface to, for instance, a PC or chartplotter. Paddlewheel to UWU NMEA Installation
NMEA 2000 Transducer Change Over Switch
The Tack Change Over Switch allows two NMEA 2000, Simnet, Seatalk NG, or CANbus ‘Smart’ sensors such as the Airmar DST800 on one instrument system or display. Boat Speed and/or Depth PGN’s are automatically routed from either the Port or Starboard transducer or boat speed sensor and output as a single source to the connected instruments. If the apparent wind information is available on the bus then the Tack COS will use this as priority for deciding which tack the vessel is on. If no wind PGN is available then the Tack COS has its own gravity change over switch built in. Installation couldn’t be easier. Simply screw to the bulkhead and connect to the bus using the supplied NMEA 2000 connection.
Gravity Transducer Change Over Switch
The standard version has change over contacts for use with more traditional sensors. However, it is no ordinary gravity change over switch. Running intelligent algorithms, the switch avoids unnecessary switching which causes inaccurate boat speed readings, delayed depth readings and early switch contact failure. With an inbuilt microcontroller, it prevents the unwanted switching between transducers whilst sailing in light breeze, downwind, motoring or stationary. The standard version works on gravity alone to calculate which transducer to use. There is also an NMEA version that takes NMEA wind angle data to calculate which tack the boat is on, but still using change over contacts to switch traditional sensors. This version is especially useful in catamarans or other craft with very small heel angle. These products are designed to work with almost any speed or depth instruments.
The NMEA Paddlewheel converts NMEA from either a GPS or electromagnetic log to a paddlewheel output suitable for connecting directly to an instrument system, such as a B&G Hydra/Hercules.
