The FTS Submersible PT provides outstanding Total Error Band (TEB)2 accuracy for reliable, accurate measurements in real-world conditions.
The FTS Submersible PT is ideally suited for environmental monitoring applications such as surface water, streams, and reservoirs using existing SDI-12 monitoring equipment.
The FTS Submersible PT is ideal for remote applications where battery-powered operation with minimal current draw and networking multiple sensors to a data recorder are required. And, the included lightning protection makes it more robust for installation in areas prone to high current and voltage transients.

1. Level range may be specified in units of bar, mbar, mH2O, psi, ftWC, or inWC.
2. Total Error Band (TEB) includes the combined effects of non-linearity, hysteresis, and non-repeatability as well as thermal dependencies, over the compensated temperature range.
3. Optional accuracy is written in compliance with USGS OSW specification mandates.
4. Optional accuracy is written in compliance with USGS OSW specification mandates and limited to a compensated temperature range of 0…40° C.
5. The Submersible Pressure Transducer SDI can communicate in either SDI-12 or RS485 at any one time. By default, the Submersible Pressure Transducer SDI will ship in SDI-12 mode. A USB Dongle is required to change to RS485 mode.
