Sensor Size: 3"x2"x1"
Weight: 0.13 lb. |
WE300 Solar Radiation Sensor
 |
Global
Water's Solar Radiation Sensor is a precision
pyranometer and includes a bubble level, leveling
screws and mounting hardware for quality
installation. The detector uses a high stability
silicon photovoltaic detector (blue enhanced) to
obtain accurate readings. Detector: High-stability silicon
photovoltaic detector (blue enhanced).
Output: 4-20 mA
Range: 0 to 1500W/m2
Spectral Response: 400 to 1100 nanometers
Accuracy: 1% of full scale
Operating Voltage: 10-36 VDC
Current Draw: Same as sensor output
Warm Up Time: 3 seconds minimum
Operating Temp: -40° to +55°C
Sensor Size: 3" diameter x 1 1/2"
Weight: 1/4 lb. |
WE550 Wind Speed Sensor
 |
The Global
Water Wind Speed Sensor is constructed of
high-impact materials, ensuring its durability and
ruggedness even in severe weather conditions. The
Wind Speed gauge measures wind speeds of up to 110
MPH with a 3 cup anemometer. The wind speed
indicator has a very low threshold, and it responds
accurately to subtle changes in wind speed.
Type: Three cup anemometer
Threshold: <=3 MPH (1.35 m/s)
Output: 4-20 mA
Range: 0 to 50 m/s (110 MPH)
Accuracy: .2 MPH over the range 11 to 55 MPH
Operating Voltage: 10-36 VDC
Current Draw: Same as sensor output
Warm Up Time: 3 seconds minimum
Operating Temp: -40° to +55°C
Sensor Size: 7" diameter x 8 1/2"
Weight: 1lb. |
WE570 Wind Direction Sensor
 |
The Global
Water Wind Direction Sensor is designed to
accurately measure wind direction even in the
harshest environments. The wind direction indicator
measures wind direction with a wind vane connected
to a potentiometer that converts the signal to a
4-20 mA output with almost infinite resolution.
Type: Wind Vane with potentiometer
Output: 4-20 mA
Range: 0-360° (352° electrical, 8° open)
Sensitivity: 1 m/s (2.2 mph)
Accuracy: 1% of full scale
Operating Voltage: 10-36 VDC
Current Draw: Same as sensor output
Warm Up Time: 3 seconds minimum
Operating Temp: -40° to +55°C
Sensor Size: 8 1/2" diameter x 10 1/2"
Weight: 1lb. |
WE600 Humidity Sensor,
WE700 Temperature Sensor,
WE770 Solar Shield
 |
The Global
Water Humidity Sensor is a precise, durable unit.
It is composed of a solid state capacitative element
with a linear amplifier.
The Global Water Temperature Sensor is a high
quality, rugged, precision RTD instrument calibrated
to US National Standards.
The Global Water Solar Shield is a ventilated sun
shield, with high reflectiveness, low heat
retention, and low thermoconductivity. The unit is
designed to protect the Global Water Humidity and
Temperature sensors from direct sunlight that may
affect the sensor's 4-20 mA output.

Weather Sensors Installation
Proper siting
for weather sensors is important to ensure accurate
readings. For example, wind sensors should not be
installed too close to a building, as turbulence created
by the building can interfere with readings. The Solar
Radiation sensor should be installed in direct sunlight
on a level surface (bubble level and leveling screws are
included with purchase).
Purchase of both the Wind Direction and Wind Speed
sensors includes a T-mounting bar with a 1" stainless
steel coupling unit and allen wrench for easy allen set
screw instalation. Individual wind sensors or solar
radiation sensors include 1" stainless steel elbow
couplers and an allen wrench. The Solar Shield (with a
stainless steel elbow coupler) can be used for
protection and easy installation of the Temperature and
Humidity sensors. The Barometric Pressure sensor can be
mounted with straps for a variety of applications
(including inside a datalogger or to a display for
hand-held use).
