Resumen
El CS120A es un sensor de visibilidad por infrarrojos de dispersión frontal para uso autónomo o en una estación meteorológica automática, para aplicaciones en carreteras, marinas y aeropuertos. El CS120A utiliza la conocida técnica de dispersión frontal para determinar la visibilidad, utilizando un ángulo de dispersión de 42° que proporciona estimaciones precisas del Meteorological Observable Range (M.O.R.) para niebla y nieve.
Para aplicaciones aeronáuticas el CS120A cumple normativas CAA y ICAO; y también las CAP437, CAP670 y CAP746.
Certificado por el Deutscher Wetterdienst para controlar la luminosidad de las balizas luminosas en los aerogeneradores de parques eólicos, según norma 506/04, General Administrative Rules for the Identification of Aircraft Obstructions.

Descripción detallada
Comparado con sensores de otros fabricantes, el diseño del CS120A permite medir la visibilidad en un espacio relativamente limpio, porqué la posición de los cabezales y cuerpo del sensor minimizan la perturbación del flujo de aire en el volumen de medición.
El CS120A utiliza muestreo a alta velocidad continuo, que mejora la precisión de las medidas tomadas en condiciones de lluvia y granizo, y proporciona lecturas fiables durante situaciones más estables como niebla y neblina. El muestreo a alta velocidad también permite que el sensor responda mejor ante cambios repentinos de las condiciones meteorológicas.
El diseño característico del CS120A permite mantener limpias las ópticas. Las ópticas mirando hacia abajo minimizan la acumulación de suciedad y nieve. Los calentadores de bajo consumo (dew heaters) evitan la formación de escarcha, mientras que los calentadores de alto consumo (hood heaters) evitan la formación de hielo.
El sensor tiene un consumo muy eficiente, de tan sólo 3 W durante un funcionamiento normal con los calentadores contra escarcha (dew heaters) activos; se puede reducir el consumo posteriormente bajando la velocidad de muestreo y realizando el control manual de los calentadores.
Hay disponibles dos salidas de alarma mediante relés, que pueden activar sistemas de aviso externos como sirenas y semáforos. También se pueden utilizar, dependiendo de los niveles de visibilidad, para controlar la intensidad lumínica de las balizas luminosas en los aerogeneradores.

Most Campbell Scientific sensors are available as an –L, which indicates a user-specified cable length. If a sensor is listed as an –LX model (where “X” is some other character), that sensor’s cable has a user-specified length, but it terminates with a specific connector for a unique system:
- An –LC model has a user-specified cable length for connection to an ET107, CS110, or retired Metdata1.
- An –LQ model has a user-specified cable length for connection to a RAWS-P weather station.
If a sensor does not have an –L or other –LX designation after the main model number, the sensor has a set cable length. The cable length is listed at the end of the Description field in the product’s Ordering information. For example, the 034B-ET model has a description of “Met One Wind Set for ET Station, 67 inch Cable.” Products with a set cable length terminate, as a default, with pigtails.
If a cable terminates with a special connector for a unique system, the end of the model number designates which system. For example, the 034B-ET model designates the sensor as a 034B for an ET107 system.
- –ET models terminate with the connector for an ET107 weather station.
- –ETM models terminate with the connector for an ET107 weather station, but they also include a special system mounting, which is often convenient when purchasing a replacement part.
- –QD models terminate with the connector for a RAWS-F Quick Deployment Station.
- –PW models terminate with the connector for a PWENC or pre-wired system.
-
Not every sensor has different cable termination options. The options available for a particular sensor can be checked by looking in two places in the Ordering information area of the sensor product page:
- Model number
- Cable Termination Options list
If a sensor is offered in an –ET, –ETM, –LC, –LQ, or –QD version, that option’s availability is reflected in the sensor model number. For example, the 034B is offered as the 034B-ET, 034B-ETM, 034B-LC, 034B-LQ, and 034B-QD.
All of the other cable termination options, if available, are listed on the Ordering information area of the sensor product page under “Cable Termination Options.” For example, the 034B-L Wind Set is offered with the –CWS, –PT, and –PW options, as shown in the Ordering information area of the 034B-L product page.
Note: As newer products are added to our inventory, typically, we will list multiple cable termination options under a single sensor model rather than creating multiple model numbers. For example, the HC2S3-L has a –C cable termination option for connecting it to a CS110 instead of offering an HC2S3-LC model.

Many Campbell Scientific sensors are available with different cable termination options. These options include the following:
- The –PT (–PT w/Tinned Wires) option is the default option and does not display on the product line as the other options do. The cable terminates in pigtails that connect directly to a datalogger.
- In the –C (–C w/ET/CS110 Connector) option, the cable terminates in a connector that attaches to a CS110 Electric Field Meter or an ET-series weather station.
- In the –CWS (–CWS w/CWS900 Connector) option, the cable terminates in a connector that attaches to a CWS900-series interface. Connection to a CWS900-series interface allows the sensor to be used in a wireless sensor network.
- In the –PW (–PW w/Pre-Wire Connector) option, the cable terminates in a connector that attaches to a prewired enclosure.
- In the –RQ (–RQ w/RAWS Connector) option, the cable terminates in a connector that attaches to a RAWS-P Permanent Remote Automated Weather Station.
Note: The availability of cable termination options varies by sensor. For example, sensors may have none, two, or several options to choose from. If a desired option is not listed for a specific sensor, contact Campbell Scientific for assistance.
