Seametrics PT12 Pressure & Temperature Transducer (Modbus / SDI-12)

The Seametrics PT12 is a submersible pressure and temperature transducer that combines a Modbus® RTU communication interface with an SDI-12 interface in a single device. The combined output lets the PT12 transform an analog sensor network into a digital sensor system and slot directly into existing SDI-12 recorders.

The transducer is engineered for noise immunity, thermal performance, and transient protection — targeted at groundwater, well, tank, tidal-level, pump-test, and flow-monitoring sites where instrumentation must survive both electrical and environmental stress.
