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 dataloggers.Read More
This product is supplied with a standard length of cable (typically 3 m) - other lengths may be available to order.
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 (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 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).

Please note: The following shows notable compatibility information. It is not a comprehensive list of all compatible products.
The CS450 can be used with the A150. The A150 is a small, self-contained junction box that allows the CS450 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 CS450 to be part of a wireless sensor network.
