Overview
The NexSens micro-T temperature logger is a self-contained, self-powered, field-rugged package capable of taking 2048 temperature samples. The logger consists of a temperature sensor, memory chip, and battery housed in a 16mm thick stainless steel enclosure that measures just over half an inch in diameter. The small size of the temperature loggers allow them to be securely mounted out of sight in important monitoring areas.
micro-T loggers are rugged enough to withstand harsh environments, indoors or outdoors. The durable stainless steel package is highly resistant to environmental hazards such as dirt, moisture, and shock with an IP 56 rating for protection against dust and moisture. For applications with continuous exposure to condensing environments, the loggers should be protected using NexSens DS9010K Underwater Housings.
The micro-T logger uses its stainless steel enclosure as an electronic communications interface. Each enclosure has a data contact, called the 'lid', and a ground contact, called the 'base'. By simply placing the logger in the DS1402 USB reader, the user can setup deployments, upload data, and view logger status using NexSens micro-T Software.
micro-T Software
NexSens micro-T software is a user-friendly software package that simplifies the task of deploying micro-T temperature loggers and managing their data. Common sampling options such as log intervals, sampling start time, and units of measurement are setup through easy to navigate dialog boxes and graphical menus.
micro-T software uses a single database to store temperature data from each logger. Each logger is stored as a "device" inside the database. When connected, the software automatically recognizes the device's unique ID. Uploading temperature data is as simple as placing a micro-T logger in the USB reader and following step-by-step instructions while the software automatically stores the data with the associated device.
For analyzing and presenting data, micro-T software includes a unique historical report creation tool that can generate customized reports with data from all loggers in a single database. While creating a report, users can include specific information about the monitoring site, location, sensors, and project along with the recorded measurements from each device. After creation, reports can be converted to PDF, exported to Microsoft Excel, sent to colleagues via e-mail, etc.
Transit Applications
Businesses desire to offer customers a guarantee of quality and freshness in regards to the products they make or the services they provide. Tracking temperature and humidity throughout the lifetime of a product or service, or throughout various stages of manufacturing and delivery, can be vital to achieving this goal.
Perishable foods or produce, beverages, flowers, plants, works of art, or containers of temperature-sensitive chemicals can use micro-T loggers to trace their exact temperatures from manufacturer to the end user. By using the worlds smallest and most cost-effective digital temperature loggers in the world, businesses can provide customers with better quality goods without sacrificing costs.
Process Monitoring Applications
micro-T data loggers are ideal for monitoring changes in temperature through manufacturing processes. Temperature-sensitive processes can be easily monitored by attaching micro-T loggers. The micro-T line offers temperature ranges from -40° C up to 140° C with an accuracy of +/- 0.5° C to encompass most process applications.
DS1923 temperature and relative humidity loggers are popular in applications where humidity levels must be tightly controlled. For example, many woodworking companies clip DS1923 loggers to all employees via DS9093N Keychain Fob to ensure that remote work areas are not subject to high humidity levels that could result in the wood warping.
Water Profiling Applications
micro-T mooring systems are the perfect solution for cost-effective temperature profiling studies such as lake stratification. Monitoring the yearly evolution of temperature stratification is a critical component in many lake management and research programs due to its pronounced effects on aquatic chemistry and biology. A typical application includes attaching multiple DS9010K waterproof housings to a stainless steel 3/16" mooring line at user-defined spaces.
With a very similar equipment list, horizontal stream profiles can easily be measured using NexSens micro-T temperature data loggers. Rather than suspending the temperature loggers vertically from a line, a horizontal line is staked into the ground and run along the stream. Horizontal stream profiles are quite popular when measuring the ecological and biological effects of industrial discharge at elevated water temperatures.
Because each micro-T logger is synchronized to the same PC clock, all micro-T loggers can take measurements in-sync at any sampling interval ranging from 1 minute to 255 minutes. This allows for the creation of a highly-effective, yet low-cost temperature string.
