Borehole pressure transducer

Gems Sensors' 2400 slim line pressure transducer measures 19 mm in diameter and features triple sealing to prevent water ingress and condensation. The unit is designed for use in water industry applications, such as level measurement in bore holes.

The cable is water blocked including the wire strands and a custom designed hermetic header has been incorporated, so only the vent tube penetrates the sensor chamber. Consequently, water cannot enter the transducer - even if the cable sheath is damaged during use.

The large bore vent tube is connected directly to the back of the sensor, which provides rapid venting - even on the longest cable run. The sensor itself is also impervious to the effects of water.

In addition, the electronics are conformally coated to protect against possible damage, in the unlikely event of water ingress. The electronics are also designed to provide fast switch on and settling - ensuring maximum battery life and ease of calibration. These factors, combined with a long fatigue life of more than 100 million FS cycles, are a benefit when the transducer is used in remote locations.

The unit is supplied in pressure ranges of 0-4 to 0-200 mwg (mA and V), 0 to 10, 20, 50, 100, 200 mwg (mV). The sensor offers good stability, long-term drift of just 0.2% pa and accuracy of 0.2% - as well as good resistance to shock and vibration.
