MODEL H-3123 SUBMERSIBLE PRESSURE TRANSDUCER The H-3123 is a Submersible Pressure Transducer used to accurately measure water level/pressure. Transmit data digitally over long cable lengths of up to 304.8 meters (1000 feet). APPLICATIONS Accurately measure ground and surface water pressure, temperature, and levels in storm water stations, stream gauge sites, waste water facilities, aquifer monitoring, and hydrometeorological systems. KEY FEATURES • Accuracy over temperature range <= 0.02% FS. For our 15 psi range this exceeds 3mm (±0.01 ft) of water • Stainless steel sensor diaphragm, ballast, and casting • SDI-12 Output • Polyurethane vented sensor cable is durable and rugged • Dry air moisture barrier system provides atmospheric compensation • No on-site calibration requir
