Output: 4-20 mA Range: 800-1100 mb Accuracy: ±1% of full scale Linearity/Hysteresis: ± 0.1% 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"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: <.5 m/s (1.11 MPH) 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. Humidity Sensor Type: Capacitance Output: 4-20 mA Range: 0 to 100% RH Accuracy: ±2% RH Operating Voltage: 10-36 VDC Current Draw: 3mA plus sensor output Warm Up Time: 3 seconds minimum Operating Temp: -40° to +55°C Sensor Size: 1 1/2" diameter x 7" Weight: 1/2 lb. Temperature Sensor Type: Precision RTD Output: 4-20 mA Range: -50°C to +50°C Accuracy: ±0.2°F or ±0.1°C Operating Voltage: 10-36 VDC Current Draw: Same as sensor output Warm Up Time: 5 seconds minimum Operating Temp: -50° to +100°C Sensor Size: 3/4" diameter x 4 1/2" Weight: 1/2 lb. Solar Shield Size: 4" diameter x 8 1/2" Weight: 1 lb. 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).
