Overview
The CS450 is a pressure transducer for water level measurements in canals, wells, ponds, harbors, lakes, streams and tanks. It has a stainless-steel case that can be submerged in most canals, wells, ponds, lakes, and streams. The CS450 outputs either a digital SDI-12 or RS-232 signal to indicate observed pressure and temperature. This output can be read by many of our data loggers.
Key Advantages
Ideal for long-term deployment in harsh conditions
Technical Description
The CS450 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 CS450 has several pressure range options and two accuracy options . 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 CS450 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).
