WIND DIRECTION TRANSDUCER - T007 TDV

Measure principle: the sensing element consists of a counterbalanced vane coupled to an optical encoder disk equipped, a series of infrared emitter – receiver LEDs (Light Emitting Diode) detects the disk position allowing in this way to calculate the wind direction, this characteristics warranty an angular resolution of ± 2° degrees.
Intelligent sensor: The transducer belongs to the intelligent sensor family as based on a micro-processor chip that execute among other functions: the correct control functioning, data pre-processing, electrical signal A/D conversion etc. This characteristics warranty excellent accuracy, long-term stability and high data reliability.
Laboratory calibration: The sensor can be supplied with a SIAP+MICROS calibration certificate or with calibration certificates issues by external primary metrological services (SIT, Colonetti, ecc).
Housing materials and International standards: The dimensions of the vane and materials used warranty high sensibility, low mechanical inertia and a low starting threshold. The transducer complies with CE EMC standards, it’s protected against over tensions and is fully compliant within the WMO (World Meteorological Organization) standards.
