Description
The datalogger is a bespoke, site specific logger with various modules and communication options, combined with a power supply, contained within a steel or reinforced ABS enclosure.We configure all the datalogging equipment to suit your individual needs and our technical expertise ensures a tailored solution to read an extensive range of sensors, in a vast rangeof environments. The datalogging system mainly includes the dataTaker DT80G/D85G GeoLogger and CEM20 models. A wide variety of communication options are available for the datalogger, 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


Key Features

Operation

The system can be setup to generate alarms remotely, via email or SMS, or locally using a siren and/or beacon if user defined parameters are exceeded.The datalogger consumes minimal power from either a 12 VDC or mains power source. Power supply options are flexible depending on the site and can include mains, solar cell, and wind generation.Increasing the channel capacity of the dataTaker DT80 range is made very easy by adding dataTaker Channel Expansion Modules (CEM20). Each CEM20 connects 20 universal data logging channels to the dataTaker data logger. A dataTaker CEM20 connects to one analogue channel of the dataTaker data logger. This effectively expands the total channel capacity of the DT80 to up to 100 sensors (with 澳门永利网站:Temperature compensation) or 300 analog inputsor and the DT85 to an incredible up to 320 sensors (with 澳门永利网站:Temperature compensation) or 960 inputs.
