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. WIND SPEED Typical accuracy Resolution Threshold WIND DIRECTION Accuracy +/- 5 degs. typical (+/- 10 degs. worst case) Resolution Generally < 1 deg. ( +/- 10 degs. at North) Threshold <0.5 m/s Instromet Weather Systems Ltd 10b Lyngate Industrial Estate North Walsham Norfolk NR28 0AJ www.instromet.co.uk - [email protected] Tel: 0044 (0) 1692 502800 4-20mA wind sensor Part number: 357 1000 0xx - Serial no:xxxxxx Wind direction Wind Speed Wind Sensor Wind speed output: 20mA = 50 m/s Supply 12 Volt D.C. @ 10 mA approximately To suitable input device 3 - core screened cable 2m supplied Wind Direction output 4-20mA Example Outputs:4mA output = 10 degs. 12 mA output = 180 degs.
