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).
Measurement Ranges (depends on option chosen)
Maximum Cable Length
1 - Includes the combined errors due to nonlinearity, hysteresis, nonrepeatability, and thermal effects over the compensated temperature range, per ISA S51.1.
2 - The high accuracy (±0.05% FS) option is not available for the 0 to 2.9 psig range option.
