Überblick

Der CS456 ist eine Drucksonde für Wasserpegelmessungen in Kanälen, Brunnen, Häfen, Seen, strömen und Tanks. Durch die Titanhülle kann er in Salzwasser und anderen korrosiven Medien eingesetzt werden. Der CS456 gibt Wasserstand und Temperatur entweder als SDI-12 oder als RS232-Signal aus und kann mit fast allen Campbell-Logger abgefragt werden.

Der CS456 ist der nachfolger des CS455. Er hat eine kleiner Lücke zwischen den Wassereinlässen und der Membran so dass weniger Luft sich dort anlagern kann, die dann vom Benutzer entfernt erden muss. Luftblasen führen zu langsamen Änderungen der Messwerte während sich die Luft im Wasser löst.

Technische Beschreibung

The CS455 consists of a piezoresistive sensor and a temperature sensor housed in a titanium case. It has a rugged Hytrel cable that remains flexible, even under harsh environmental conditions. The cable incorporates a vent tube to compensate for atmospheric pressure fluctuations. The vent tube terminates inside a desiccant tube, which prevents water vapor from entering the inner cavity of the transducer.

The CS455 has several pressure range options and two accuracy options (see Ordering Info). The standard accuracy option provides ±0.1% FS TEB over the 0° to 60°C temperature range. The high accuracy option provides ±0.05% FS TEB over the 0° to 60°C temperature range and includes a calibration certificate. TEB is the combined errors due to nonlinearity, hysteresis, non-repeatability, and thermal effects over the compensated temperature range, per ISA S51.1. Please note that the high accuracy option is not available for the 0 to 2.9 psig range option.

Campbell Scientific offers the A150 Desiccated Case that allows the CS455 to be connected to a CWS900 Wireless Sensor Interface (for use in a wireless sensor network) or to be connected to a prewired enclosure (see Ordering Information).

Additional Compatibility Information

Desiccated Case

The CS455 can be used with the A150. The A150 is a small, self-contained junction box that allows the CS455 to be connected to a continuation cable, a prewired-enclosure connector, or a CWS900-series wireless-sensor connector. Connection to a CWS900-series interface allows the CS455 to be part of a wireless sensor network.
