3700 Series - Submersible Transducer for Harsh Environmental Service Hastelloy®/UNS31803SS Construction Triple Sealed to Ensure Immersible Integrity <10ms Switch On/Settling Period 19mm Diameter Gems Sensors 3700 Series immersible pressure transducer has been specifically designed to meet the rigors of long term immersibility in harsh environments. A custom designed hermetic header guarantees that water cannot enter the transducer even if the cable sheath is damaged during use. The large bore vent tube is connected directly onto the back of the sensor which provides rapid venting, even on the longest cable run. The sensor itself is impervious to the effects of brackish and salt water. The all welded electronics enclosure is completely segregated from all other areas, with the electronics themselves designed to provide fast switch-on and settling to ensure maximum battery life and ease of calibration.
