CGEO-DT80G DT85G CEM20

Description

The datalogger is a bespoke, site specific logger with variousmodules and communication options, combined with a powersupply, contained within a steel or reinforced ABS enclosure. We configure all the datalogging equipment to suit yourindividual needs and our technical expertise ensures a tailoredsolution to read an extensive range of sensors, in a vast range of environments. 

The datalogging system mainly includesthe dataTaker DT80G/D85G GeoLogger and CEM20 models. Awide variety of communication options are available for thedatalogger, including: 

Direct link to PC or laptop 

Fibre optic link 

Extended RS485 link (up to 13Km) 

Satellite up link 

Cellular (GSM/GPRS) modem 

Telephone modem 

IP via GPRS modem, i.e. direct to internet 

Dedicated radio communication

Applications

The Dataloggers can monitor a wide variety of geotechnicaldatalogging applications. They are ideally suited for structuraland geotechnical monitoring and are used extensively in harshenvironments on projects around the world. Typical applications include: 

Concrete curing 

Earthquake early detection

Dams and bridges 

Land slide 

Mining exploration 

Pipelines monitoring 

Railways 

Rock falls 

Tunnels

Operation

The system can be setup to generate alarms remotely, via emailor SMS, or locally using a siren and/or beacon if user definedparameters are exceeded. The datalogger consumes minimal power from either a 12VDC or mains power source. Power supply options are flexibledepending on the site and can include mains, solar cell, and windgeneration. Increasing the channel capacity of the dataTaker DT80 range ismade very easy by adding dataTaker Channel Expansion Modules(CEM20). Each CEM20 connects 20 universal data loggingchannels to the dataTaker data logger. A dataTaker CEM20connects to one analogue channel of the dataTaker data logger.This effectively expands the total channel capacity of the DT80to up to 100 sensors (with temperature compensation) or 300analog inputsor and the DT85 to an incredible up to 320 sensors(with temperature compensation) or 960 inputs.
