ESDL-30 Data Logger for Vibrating Wire Sensors
Product description
The ESDL-30 datalogger is designed for data acquisition from sensors via the SDI-12 interface. All types of sensors—MEMS, vibrating wire, and strain gauge sensors—can be connected through the SDI-12 interface. The datalogger features a wide operating temperature range, low power consumption, and compatibility with various telecommunication systems as well as different measurement and control applications.
The datalogger can be connected to a large number of SDI-12-compatible sensors. It can be programmed to perform measurements at intervals ranging from 5 seconds to 168 hours in linear mode, allowing the number of daily measurements to be minimized, which significantly saves battery power. The SDI-12 interface greatly reduces cabling costs, as only a 3-core cable is required to connect sensors, multiplexers, and loggers into a single network.
In addition to sensor data, the datalogger stores battery charge status, current date, and time in non-volatile memory.
