12. W IND SPEED AND DIRECTION SENSOR

13. Gill ultrasonic wind sensors are true solid-state devices No need for regular maintenance, making them the ideal choice for a wide range of applications, particularly those in hostile environments.

14. W IND OBSERVER All Wind Observer sensors have an IP66 rated stainless steel construction. The Wind Observer 65, 70 & 75 are available with a range of mounting and connection Wind Observer IS has approval for use in hazardous petrochemical environments

15. W IND OBSERVER 65 The Wind Observer 65 will monitor wind speeds up to 65m/s(145mph) and provides data via digital and optional analogue outputs. This wind sensor is particularly suitable for use in land based and marine environments.

16. D ETAILS OF W IND OBSERVER 65 Wind Speed Range 65m/s (145mph) Construction Stainless Steel Operational Temp -55°C to +70°C Weight 1.4kg (50oz)

17. W IND OBSERVER 70 The Wind Observer 70 will monitor wind speeds up to 70m/s (157mph) and has been accepted for service by the FAA and CAA for reporting of surface wind in airport applications

18. D ETAILS OF WIND OBSERVER 70 Wind Speed Range 70m/s (157mph) Construction Stainless Steel Operational Temp -55°C to +70°C Weight 1.4kg (50oz) Heating Option High Power

19. WIND OBSERVER 75 The Wind Observer 75 will monitor wind speeds up to 75m/s (168mph) and features 150 Watts of electrical heating power in the anemometer head. This sensor has been designed for use in freezing weather conditions
