CADEANCO manufactures two OEM Voltage measurement data loggers for clients that are custom designed to record data from their range of sensors for geotechnical applications.  Loggers are housed in a polycarbonate housing for clients to incorporate in their own external case.   Connections to the logger are easily made via screw terminal connectors and a series of pre-drilled cable access ports provides flexibility for cabling.  The loggers use an external, user-supplied power source including the option of a lead-acid battery with solar charging or AC power module.  With a stand-by current of only 65uA, these loggers are ideal for use in applications where re-charging is impractical and access for battery replacement is difficult.

Loggers can be ordered with access options for initial configuration and data recovery.  Standard options include a RS232 port, a USB access port, LoRaWAN data push, a 4G GSM Modem or a FTP modem to push data to a private server.

ISO 9001 Certified

More Information
