Keller DCX-22 AA data logging probes for water level monitoring

Click2Contact

Bestech Australia introduces Keller DCX-22 AA data logging probes to monitor groundwater levels and tank filling levels, which can be used under a wide range of conditions.

The design utilises two AA (absolute-absolute) sensors technology; hydrostatic and barometric probes. These probes offer fully autonomous operations, or they can also be used as an integrated data logger, wireless transmitter, an ambient-pressure compensating capillary or a separate absolute pressure sensor. The probes are designed for robustness and long-lifetime operations of 10 years.

The electronics employ the latest microprocessor technology for high-resolution reading from both hydrostatic and barometric sensors. The devices are highly resistant for use in humid and damp environments, and will not be affected by a short period of flooding.

The DCX probes can be adapted for event-controlled reading using the user-friendly GUI so that only useful data are stored in the probes. The captured data can be retrieved either by manual download using USB cable or through wireless GSM data transmission from the remote location. The data can also be sent to any mobile device as a short message (SMS).

Key features include: pressure range of 800–2300 mbar absolute; accuracy of ±0.05% of FSO; resolution of ±0.0025% of FSO; and a probe diameter of 22 mm.
