Resumen

El WXT520 es un instrumento meteorológico todo en uno que mide velocidad y dirección de viento, precipitación, presión barométrica, temperatura y humedad relativa del aire. Su pequeño tamaño lo hace ideal en instalaciones rápidas y aplicaciones de duración limitada. El WXT520 no está pensado como alternativa a una estación meteorológica de grado científico.

Descripción detallada

The WXT520's wind sensor consists of three equally spaced transducers that produce ultrasonic signals. Wind speed and direction are determined by measuring the time it takes for the ultrasonic signal of one transducer to travel to the other transducers.

Precipitation is measured one raindrop at a time. Whenever a raindrop hits the precipitation sensor, an electrical signal is produced that is proportional to the volume of the drop.

The WXT520 has a PTU module that contains a capacitive silicon BAROCAP® sensor for barometric pressure measurements, a capacitive ceramic THERMOCAP® sensor for air temperature measurements, and a capacitive thin film polymer HUMICAP® sensor for relative humidity measurements. The PTU is housed in a naturally-aspirated radiation shield that protects it and reflects solar radiation.

Mounting

The WXT520 is shipped with a mounting tube. The mounting tube fastens to a CM202, CM204, or CM206 crossarm via the CM220 Right Angle Mounting Bracket or 17953 1-in x 1-in NU-RAIL Fitting.

The 25299 is an optional mounting kit for the WXT520. It provides better water protection. When using the 25299, the WXT520’s IP classification is IP66; otherwise its classification is IP65. The 25299 fastens to a crossarm via the CM220 bracket or 17953 NU-RAIL fitting.

Bird Spike Kit

The 25300 Bird Spike Kit is used to discourage birds from roosting on the WXT520. This kit is fastened on top of the WXT520. It consists of a metallic band with spikes pointing upward. The spike’s shape and location ensure minimal interference of wind and rain measurements. The spikes are designed not to hurt the birds. Please note that when the kit is attached to the WXT520, more snow can accumulate on the WXT520, and the snow may melt slower.

  1. The unit needs to be sent to Vaisala for repair.

  2. The information included on a calibration sheet differs with each sensor. For some sensors, the sheet contains coefficients necessary to program a datalogger. For other sensors, the calibration sheet is a pass/fail report.

  3. This depends on the information contained in the calibration sheet:

    • If the calibration sheet contains coefficient information, Campbell Scientific keeps a copy, and a replacement copy can be requested.
    • If the calibration sheet does not contain coefficients, Campbell Scientific does not keep a copy. It may be possible to contact the original manufacturer for a replacement copy.
