T24-WSS [Wind Speed Sensor]

Overview
The T24-WSS wireless anemometer is built on the same technology as previous Mantracourt wireless sensors
interfaces offering the same sleep and wake functionality and operation with peripheral devices including
handhelds, USB base stations and GPRS data loggers.
The Anemometer features a high quality 3-cup rotor pressed on a stainless steel shaft with rugged Delrin body
with bronze Rulon bushings
The output value of the anemometer can be calibrated and configured to the user's requirements and measure
over the range 5 to 125 mph.
Accuracy:
0.5mph from 5 to 10 mph
•
± 4% from 10 to 125 mph
•
The T24-WSS is powered either from internal batteries or an external supply. For applications which require high
sampling rates for long periods Mantracourt's PowerPack1 and SolarPanel1 (PP1 & SP1) offers an ideal solution.
Communications
To configure the device you will use the Read and Write mechanisms described in the Data Packet Structures
section to read and write parameters and execute commands.
