Sensors

Tougher materials stand up to the toughest environments
The Model C3 rotor is made of tough polycarbonate for exceptional durability and reliability. The Model C3 sensor base is also made of rugged polycarbonate, making it more resistant to damage during installation. The Unique Bearing System Assures that wind blown dirt and moisture will not destroy the bearings and degrade Performance. Recorded Wind speeds up to 97 m/sec, make the C3C Anemometer the first choice for professional use in all fields.

Second Wind C3C Anemometer
The Second Wind C3 anemometer offers a new choice, including calibrated or uncalibrated anemometers to meet your needs. Our Model C3C anemometer has been calibrated at the highly respected Massachusetts Institute of Technology’s Wright Brothers wind tunnel. MEASNET Calibrated Anemometer is also available.

Second Wind PV-1 Wind Vane
The PV-1 is a continuous-rotation potentiometric wind direction vane. It is ideal for applications including wind resource assessment, meteorological studies, and environmental monitoring. The mechanical range is a full 360 degrees with continuous rotation, and the instrument is compatible with all Nomad data loggers from Second Wind and similar data logging devices. The Second Wind PV-1 Wind Vane has an innovative design featuring drip overhang to prevent icing. Combine this with a reduced dead band of as little as three degrees, and you get more reliable performance and accurate reads all the way around.

The Vector A100 Anemometer
The A100 Anemometer has a 3 cup rotor running a shaft, and is available as either a passive version using a magnetically-actuated switch or an active version using a chopped optical beam. Both versions provide pulse signals proportional to the wind speed being monitored. However, the active version provides more pulses for greater signal resolution when determining turbulence. A MEASNET calibration service is also available.

SWI Thermister with Radiation Shield
The SWI Thermister is designed specifically for use with the nomad 2 wind resource assessments data logger. It consists of a 10K type thermister encased in a aluminum shaft, and comes pre wired with 3.5 meter of sensor cable with radiation shield to minimize errors from gains due to direct sunlight. The sensor is ideal for collecting temperature data for energy density calculations and monitoring air temperature at remote sites.

The six plated shield can be mounted to a 1 to 2 inch diameter pipe with a U-bolt clamp or a larger diameter mast with hose clamp.

Setra Barometric Pressure Transducer
Setra systems has been a technology leader in environmental pressure measurement for over three decades. The model 276 is an extremely accurate and stable transducer based on the proven setracreamTM sensing element. Another major features of the 276 is setra's custom application specific integrated circuit (ASIC). The ASIC works hand in hand with the setracreamTM sensor to achieve long term stability and high accuracy.

Li-Cor-2005Z Pyranometer Kit
The Li-cor Pyranometer kit is designed for a field measurement of global solar radiation in agricultural, metrological and solar energy studies. In clear unobstructed daylight conditions the Li-Cor Pyronometer compares favorably with first class thermopile type Pyronometer but is priced at a fraction of the cost.

Vaisala Humidity Sensor
The Vaisala Intercap Humidity and Temperature Probe HMPSO is a simple and cost effective humidity transmitter suitable for volume application on integration into other manufacturer equipment. Because of its very low current consumption and short up 4me. The 4MP50 is well suitable for battery powered applications.

The RM Young Rain Gauge
This high quality rainfall measurement sensor consists of a large collection area (200cm2) and two tipping buckets with a switch. Accuracy is 2% up to 25mm/hr and 3% up to 50mm/hr and is available with or without heater. The sensor is designed to be self-cleaning and has leveling screws built in. Operating temperature range of -20 to + 50C. WMO standard resolution of 0.1mm per switch actuation.

Booms
Side mount booms are used to mount Second Wind Anemometer or Wind Direction Vane to Shah Masts up to 8 inches in diameter. Made of galvanized steel, these 2.2 m & 1.5 m booms resist corrosion and mount sensors away from Shah Masts to minimize mast induced flow distortions.

• For use with Second Wind Anemometer or Wind Direction Vane
• Easy to assemble
• Robust, dual-beam support structure
• Mounting bracket tabs assure proper boom installation
• Self-aligning mounting bracket assures secure, 90-degree vertical orientation
• Meets or exceeds industry IEC 61400-12-1 recommendations for mast and boom offset distances.

Wavecom (GSM) Modem (remote date collection)
Dial the NOMAD 2 from your office computer to view real-time data from all sensors. Use the Zoom inputs button in NOMAD Desktop to make sure all devices connected to the logger are functioning properly and to check the battery voltages. Use the Zoom Nomad 2 button to view the amount of space remaining on the Compact Flash card, the local time at the logger, the version of firmware running on the logger, and more.

Solar Panel with 12 V battery
In most remote circumstances, the 12 V battery will be charged by a combination of an externally mounted 10 watt solar panel to use as part of a charging system to power a modem or sensors recurring additional power.

Cables
0.5 Sq.mm , 5 & 3 Core cables with and Without Shield available to connect between Sensors and Data Logger with Numeric Coding.

Inspeed Vortex Hand Held Wind Meter
Inspeed 3-Cup rotor. Tilts flat for storage. Does not care where unit is pointed. Reed switch/magnet provide 1 pulse per rotation. approx. 3 mph to 125+ mph (~5 kph to over 200 kph). Pole Mount Hand Held Anemometer are also available.

Grounding Kit
Meteorological sensors, loggers, and masts accumulate static charge unless they are properly grounded. High winds, low humidity, and the height of the mast above ground increase the rate of charge accumulation.

A properly installed grounding kit protects your sensors and loggers from electrostatic discharge (ESD) by bringing the mast and everything mounted on it to ground potential. The copper-clad lightning spike provides an umbrella of protection for sensors at the top of the mast
