Multi-channel Datalogger
ESDL-30 datalogger is designed to log data from sensors with SDI-12 interface. Any sensor with a SDI-12 signal interface can be connected to the datalogger. It can be programmed to take a measurement from 5 seconds to 168 hours in linear mode. All the measured data is stored together with the current date, time and battery voltage, as a data record in the internal non-volatile memory of the datalogger.
Following options are available:
- > Telemetry through GSM/GPRS modem
- > Readout/data retrieval using laptop
The SDI-12 system allows a huge reduction in cabling costs as only a single three conductor cable is required to interconnect the sensors, multiplexers and dataloggers in a network that can be spread over a wide area.
Encardio-rite provides SDI-12 interface units for various types of sensors like vibrating wire, resistive strain gage type, MEMS technologies tipping bucket rain gauge etc. to connect to Encardio-rite model ESDL-30, SDI-12 interface datalogger.
