The SPT Dry Air System prevents moisture from condensing in the submersible pressure transducer, provides compensation for changes in atmospheric pressure without impairing the sensor's accuracy. This system also eliminates moisture in the vent tube which can block the tube and prevent accurate measurements.
The system includes a desiccant case which is a desiccant chamber for pressure transducers. The pressure transducer vent tube terminates inside the case, which vents to the atmosphere.
