With options for SDI-12, RS-232, RS-485, and Modbus interfaces, to name a few, data loggers from NexSens Technology are capable of working with nearly any sensor that utilizes an analog or digital connection.
These data loggers offer superior data acquisition performance in extreme conditions, and they are specifically designed for remote environmental monitoring applications. There are options for landline phone, cellular, radio, Ethernet, WiFi, and satellite telemetry.
NexSens data loggers are commonly used to read and transmit data from multiparameter datasondes, including datasondes from Hydrolab. Hydrolab datasondes, such as the DataSonde 4a or minisonde, typically posses both SDI-12 and RS-232 interface options, allowing them to work seamlessly with advanced NexSens data logging solutions.
A NexSens data logger simultaneously supports eight analog inputs and four digital inputs for multi-sensor data logging capability. All electronics are housed in a rugged, NEMA 4X enclosure constructed of heavy-duty fiberglass. The built-in 8.5 amp-hour sealed lead acid battery provides 12-volt power to the system, and the battery can continuously charge using AC or solar power. Polymer-coated circuit boards, sealed connectors, corrosion-resistant stainless steel hardware, and built-in lightning protection ensure reliable performance in even the harshest conditions. All sensor cables run through waterproof gland fittings to ensure protection from the elements.
The NexSens SDL500 submersible data logger is also available for situations in which the data logger will be exposed to more severe environmental conditions. The SDL500 can withstand extreme wave action, drops, and floods. It consists of the data logger and communications module housed in a fully-submersible, five-inch-diameter round enclosure. It can be outfitted with either a spread-spectrum radio or cellular modem and antenna for real-time communication. It also offers five sensor ports for connection to industry-standard digital and analog sensors and datasondes. Each sensor port offers a UW receptacle connection with double O-ring seals for waterproof sensor connections. (Learn more about this underwater data logger.)Expansive Device Library: iChart Software
Both data loggers are capable of working with iChart Software, a complete, ready-to-use software package that simplifies and automates many of the tasks associated with acquiring, processing, analyzing, and publishing environmental data.
iChart offers the industry’s largest device library for integrating data from popular environmental sensors and systems, including datasondes from Hydrolab. Simply select the manufacturer and model number from a device index. A built-in device profile simplifies the setup and eliminates complex sensor programming.
The software has been designed with an open architecture, offering an easy-to-use set of tools to configure and customize monitoring projects. The graphical user interface eliminates the need for learning complicated programming languages to set up and maintain a network of remote sensors.
