GENERAL DESCRIPTION
The SDI-12 Submersible Pressure Transducer (SDI-PT-KEL) is designed for freshwater level
measurements. Typical applications include lakes, streams, wells, agricultural water level/flow, and
tanks.
The SDI-PT-KEL can be supplied with either a stainless steel (SDI-PT-SS-KEL) or a titanium (SDI-PT-TT-
KEL) case and with either a bayonet connector for use with FTS Axiom Dataloggers or with flying
leads for use with other data loggers.
A vent tube incorporated in the cable vents the sensor diaphragm to the atmosphere. This
eliminates the need to compensate for changes in barometric pressure. Care must be given to
prevent the vent tube from being pinched or crushed which can result in erroneous readings.
Ensure the cable is free from obstructions and kinks.
To prevent water vapor from entering the inner cavity of the sensor, which can cause erroneous
data and damage to the sensor, the vent tube opening terminates inside a desiccated vent tube
enclosure.
