技术说明

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.

  1. The CS45x-series pressure transducers are suitable for monitoring lake levels. However, be sure to submerge the pressure transducer below the frost line. If ice forms against the diaphragm, it will deform the diaphragm and cause permanent damage.

  2. No. Because of the SDI-12 protocol, the CS45x-series pressure transducers can only make measurements every 1.5 seconds.

  3. No. To prevent damage to the pressure transducer, it must be removed if freezing is anticipated.
  4. Yes, but a data logger is required. The CS45x-series pressure transducers are not autonomous. They require a data logger to initiate and retrieve a measurement. The data logger can initiate an event-based measurement.

    In contrast, the CRS45x-series water-level recording sensors support event-based recording using built-in data-collection features. 

  5. No. A data logger must be used with the CS45x-series pressure transducers.

  6. No. The A200 is only used to configure the CS451 and CS456 pressure transducers.
