The TECMES Model TS235 anemometer is a static 2-axis ultrasonic sensor used to measure wind speed and direction, U-V Cartesian components of wind speed.

Wind speed and direction are determined by measuring the transit time of the ultrasonic pulses between two pairs of ultrasonic transducers.

Serial interfaces RS232, RS485, and SDI-12 with NMEA communication protocols, and SDI-12 are available on the sensor.

All versions have two analog outputs for wind speed and direction, factory congurable between 4 to 20 mA (standard), 0 to 5 V.

The option can also be supplied with heating, which prevents snow accumulation and ice formation, allowing precise measurements in extreme environmental conditions.

The installation is carried out on a 1.5 ”or 2” mast by means of the accessory that accompanies the sensor. The electrical connection is made through the 12-pin connector located on the bottom of the instrument.

The low consumption of the instrument allows installation in remote sites,

with power from photovoltaic panels and backup battery.

The absence of moving parts minimizes instrument maintenance.
