The PCE Instruments 110V-230V AC Wind Speed Meter (PCE-WSAC 50W+ 230) is a wireless wind monitoring and alarm system designed for construction cranes, wind turbines, industrial structures, mines, factories, and other applications where changing wind conditions require continuous observation. The remote wind sensor measures velocities from 1 to 50 m/s and transmits readings to the AC-powered display/controller through an IEEE 802.15.4 ISM 2.4 GHz wireless link, providing up to 750 meters of open-field transmission range or approximately 60 meters indoors. Configurable pre-alarm and main-alarm thresholds provide optical, acoustic, and relay-based warnings when preset wind speeds are reached. The system stores up to 30,000 records internally and supports microSD storage for additional logging. Industrial connectivity includes RS485, 4–20 mA signals, and pulse input capability, allowing the wind data and alarm functions to interface with compatible control and monitoring systems. Key Features and Benefits: Wireless Wind Monitoring: Transmits real-time wind-speed measurements over the 2.4 GHz ISM band without requiring a direct data cable between the remote sensor and display/controller. Wide Wind-Speed Range: Measures from 1 to 50 m/s, equivalent to approximately 4 to 180 km/h or 2.5 to 112 mph, for monitoring normal winds through strong gust conditions. Dual-Stage Alarm System: Supports configurable pre-alarm and main-alarm thresholds with separate optical, acoustic, and relay-based warning responses. 30,000-Record Data Logging: Stores wind-speed measurements internally for later operational review, maintenance analysis, and documentation. Expandable microSD Storage: Supports cards up to 32 GB and includes an 8 GB microSD card for removable data storage. Adjustable Logging Interval: Records measurements at user-selectable intervals from 10 seconds to 1 hour. Industrial System Integration: Provides RS485, pulse input, and 4–20 mA connectivity for compatible PLCs, monitoring systems, and control equipment. Long-Range Wireless Communication: Supports transmission distances up to 750 meters in unobstructed open-field conditions or approximately 60 meters indoors.

Package Contents: PCE-WSAC 50W+ 230 display/controller, wind speed sensor with standard bracket, self-levelling additional bracket, radio antenna, 1.5V D-cell battery, 8 GB microSD card, and user manual How to Use: Select the Sensor Location: Choose an outdoor mounting point with unobstructed airflow and adequate clearance from structures or objects that could create turbulence and distort measurements. Mount the Wind Sensor: Secure the sensor to the intended structure using the supplied standard bracket or self-levelling additional bracket according to the installation requirements. Install the Sensor Battery: Insert the supplied 1.5V D-cell alkaline battery into the sensor using the specified polarity and secure the battery compartment. Install the Controller: Position the display/controller within the supported wireless range and connect the supplied radio antenna to the designated connection. Connect Mains Power: With the circuit de-energized, connect the controller to a suitable 110–230V AC, 50/60 Hz supply using appropriate electrical installation procedures and qualified personnel where required. Configure Alarm Thresholds: Set the desired pre-alarm and main-alarm wind speeds according to the operating limits established for the monitored equipment or site. Configure Data Logging: Select a recording interval between 10 seconds and one hour and insert the supplied 8 GB microSD card when removable storage is required. Connect External Systems: With power isolated, connect compatible RS485, 4–20 mA, pulse, or alarm-relay circuits according to the applicable terminal assignments and electrical ratings. Verify System Operation: Apply power, confirm communication between the sensor and controller, verify the displayed wind-speed reading, and test configured alarms and external outputs before relying on the installation. Monitor and Maintain: Observe real-time wind conditions, respond according to established site procedures when alarms activate, and periodically inspect the sensor, brackets, battery, antenna, and electrical connections. Benefits of Using PCE Instruments 110V-230V AC Wind Speed Meter (PCE-WSAC 50W+ 230): Improves Wind-Risk Awareness: Configurable warning thresholds alert operators when measured wind conditions approach or exceed established operating limits. Supports Safer Equipment Decisions: Real-time wind monitoring provides additional information for determining whether cranes, turbines, temporary structures, or industrial operations should continue under changing conditions. Reduces Sensor Cabling: Wireless communication allows the outdoor sensor and indoor controller to be separated without a dedicated measurement cable between them.
