DYACON UA-1 Manual Product Overview
3.0 Product Overview
3.1 Product Description
Dyacon UA-1TM is an ultrasonic anemometer developed by Calypso Instruments with
modifications by Dyacon. The wind sensor may be used as a standalone sensor, a component of
Dyacon weather station, or integrated into other automated equipment.
UA-1 is a digital sensor, sending instrument data and receiving control commands via a digital
serial port using Modbus-RTU protocol over TIA-485-A (RS-485). Consequently, there is no
measurement degradation due to cable length.
UA-1 is easily mounted on the end of a vertical /4” pipe with no additional hardware. Other
fittings and mounting adapters may be developed as needed.
Sensor Protocol Descriptions
Modbus-RTU (RS-485) is an electrically robust protocol used in automation systems, such as
programmable logic controllers (PLCs). UA uses a default data rate of 19200 bps, ensuring
adequate data throughput while extended cable length capability.
Design Objectives
The design for UA-1 was designed to meet the following objectives.
•Minimize installation hardware and complexity
•Flexible cable routing – The cable can be routed inside or outside of the mounting pipe.
•Reduce wear components
•No wind direction dead spots
•Durable construction
•Field serviceable – Cable may be replaced by the user.
