Ideal para uso a largo plazo en duras condiciones
Resumen
El CS456 es un transductor de presión para medir el nivel de agua en canales, pozos, estanques, puertos, lagos, ríos y tanques. Con carcasa de titanio, puede sumergirse en agua salada y en otras duras condiciones. La salida de señal está disponible tanto en digital SDI-12 como RS232, y nos devuelve valores de profundidad y temperatura del agua. Estas señales pueden leerse en la mayoría de nuestros dataloggers.
El CS456 es una versión mejorada del CS455. El nuevo transductor tiene un espacio más pequeño entre los orificios de entrada de agua y el diafragma, de forma que queda atrapado menos aire y que el usuario debe quitar durante su uso. El tener aire atrapado hace que las lecturas del transductor tengan deriva en función de la lenta disolución del aire en agua.

Descripción detallada
El CS456 está formado por un sensor piezoresistivo y un sensor de temperatura, alojados en un cuerpo de titanio. Tiene un cable resistente Hytrel que sigue siendo flexible incluso en condiciones ambientales adversas. El cable incorpora tubo de venteo para compensar las fluctuaciones de presión atmosférica. El tubo de venteo dentro de un tubo desecante, evita que el vapor de agua ingrese en la cavidad interna del transductor.
El CS456 está disponible en varios rangos de presión y en dos opciones de precisión (consultar). La opción con precisión estándar proporciona ± 0.1% FS TEB en el rango de temperatura de 0° a 60 °C. La opción de alta precisión proporciona ± 0.05% FS TEB en el rango de temperatura de 0° a 60 °C e incluye certificado de calibración. TEB corresponde al error combinado debido a la no linealidad, histéresis, no repetibilidad y efectos térmicos sobre el rango de temperatura compensado, según ISA S51.1. Tenga en cuenta que la opción de alta precisión no está disponible para la opción de rango de 0 a 2.9 psig.
Campbell Scientific ofrece como opción el estuche de desecado A150 que permite que el CS451 se conecte a un armario precableado (consultar).

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.
