Technical Description

The CS451 consists of a piezoresistive sensor and a temperature sensor housed in a 316L stainless-steel 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 sensor ships with a desiccant tube that can be replaced in the field.

The CS451 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 certificateTE.B 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 0to 29 psig range option.

Campbell Scientific offers the A150 Desiccated Case that allows the CS451 to be connected toa prewired enclosure (see Ordering Information).
