Current Draw: Same as sensor output
Warm Up Time: 3 seconds minimum
Operating Temp: -40 to +55C
Sensor Size: 7" diameter x 8 1/2"
Weight: 1lb.

WE570 Wind Direction Sensor

Wind Direction Weather Sensors 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 +55C
Sensor Size: 8 1/2" diameter x 10 1/2"
Weight: 1lb.

WE600 Humidity Sensor, WE700 Temperature Sensor, WE770 Solar Shield

Humidity Weather Transmitters,Temperature Weather Instruments 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).
