Water pressure transducer CS451

relativepiezoresistiveRS-232

The CS451 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 CS451 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. The CS451 replaces the CS450 transducer. The new transducers have a smaller gap between the water ports and the diaphragm so that less air is trapped that the user must remove during deployment. Trapped air causes the transducer's readings to drift as the air slowly dissolves into the water. Benefits and Features - Quality construction to ensure product reliability - Rugged stainless-steel case protecting the piezoresistive sensor - Compatible with most Campbell Scientific data loggers - Fully temperature-compensated - Low-power sleep state between measurements to reduce power consumption - Optional weighted nose cone to facilitate submersion - Optional NPT nose cone to enable usage in closed-pipe applications - Quick shipment after receipt of order (ARO) 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.
