WIND SENSOR with 4-20mA outputs

Product catalog summary

Overview: The document describes a combined wind speed and direction sensor manufactured by Instromet Weather Systems Ltd. The sensor is constructed from anodized aluminium alloy, uPVC, stainless steel, and polypropylene, making it lightweight yet robust. It is designed for easy installation on a mast with a diameter of 30-50 mm using a V-shaped clamp and bracket.

Specifications:

Wind Speed: Accuracy is 5% or 1.5 m/s, with a resolution better than 0.5 m/s and a threshold of less than 0.5 m/s.
Wind Direction: Accuracy is +/- 5 degrees typically, with a worst-case scenario of +/- 10 degrees. Resolution is generally less than 1 degree, with a threshold of less than 0.5 m/s.

Output and Power:

The sensor outputs wind speed and direction using a 4-20mA signal.
Wind speed output is calibrated such that 20mA corresponds to 50 m/s.
Wind direction output examples include 4mA for 10 degrees, 12mA for 180 degrees (South), and 20mA for 360 degrees (North).
The power supply required is 12V DC at approximately 10mA.

Installation: The sensor comes with a 3-core screened cable (2m supplied) for wind speed output and a 4-core cable (25m supplied, 100m max) for connection to the wind sensor.

WIND SENSOR with 4-20mA outputs Part numbers: 357 1000 007 - Basic 357 1000 008 - Pro POINT NORTH WIND SENSOR The combined Wind Speed and Direction Sensors are manufactured from anodized aluminium alloy, uPVC and stainless steel with moulded polypropylene cups.The units are lightweight (less than 250 grammes) yet very robust. The sensors are designed to be mounted to a mast of between 30 - 50 mm diameter by means of a V -shaped clamp and bracket. This allows simple orientation of the sensor arm to North using the compass provided ; the only setting up required. Wind Direction is sensed by a precision conductive potentiometer which combines exceptionally long life with high sensitivity.
