New Rugged Pressure Transducer

The CS451 from Campbell Scientific (UK) is a temperature-compensated pressure transducer for water-level measurements in canals, wells, ponds, harbours, lakes, streams and tanks. For reliable operation the probe features a rugged stainless-steel case and a Hytrel cable that remains flexible, even under harsh environmental conditions. An NPT fitting allows it to be used in closed-pipe applications.

The CS451 replaces the older CS450 transducer with the new probe having a smaller gap between the water ports and the diaphragm less trapped air for the user to remove during deployment. Trapped air causes the transducer's readings to drift as the air slowly dissolves into the water. The CS451 outputs either a digital SDI-12 or RS-232 signal to indicate observed pressure and temperature.
