CS451 Stainless-Steel Pressure Transducer

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 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 CS451 to be connected to a  prewired enclosure.
