dataTaker DT85M Logger

Versatile Measurement

Connect an array of sensors through the versatile analog and digital channels, high-speed counter inputs, phase encoder inputs and programmable serial sensor channels.

Temperature, voltage, current, 4-20mA loops, resistance, bridges, strain gauges, frequency, digital, serial and calculated measurements can all be scaled, logged and returned in engineering units or within statistical reporting.

Set up sampling, logging, alarm and control tasks to suit your own requirements while interfaces for smart sensors, GPS and other intelligent devices expand the DT85M flexibility.

Designed For Remote Applications

The dataTaker DT85M intelligent data logger is a fully featured low-powered logging platform with an integrated cellular modem, making it perfect for remote applications. The rugged design and wide operating temperature range of the DT85M provides reliable operation in virtually any environment.

The DT85M’s perfect balance of performance with low-power also allows you to use a smaller solar panel without compromising on functionality.

Automatic Data Delivery

Forget travelling long distances to get your data. Utilise the DT85M’s automatic data delivery features to schedule your data to be automatically emailed to your inbox every day, week, month or other time interval.

More sophisticated systems can make use of the automatic data delivery features to send logged data to an FTP server. Alarm conditions can also trigger data delivery in addition to sending alarm messages to multiple email addresses or mobile phones.

Easy to Configure

The DT85M is configured directly in your web browser using dataTaker’s dEX graphical interface. dEX takes you through the configuration of your logger, showing you wiring diagrams and allowing you to decide – in as much or as little detail – how you want to the system to work, suiting both novice or advanced users.

Using the internal modem you can even re-configure your system remotely over the internet if required.

thermal tank testing

Comparing Thermal Efficiency of Materials

Our client – a major research organization – had a project where they were to compare the effects of various surfacing materials on a series of tanks and how efficient these surfaces were in reducing temperature losses. The temperature in the tanks was to be cycled up to 60°C by internal steam coils and allowed to cool. The temperatures were to be logged at all times with sensors at various depths within the tanks. Data collection needed to be simple, but remote communications were unnecessary…

Rice Crop Research

In the surrounds of the city of Guangzhou, a spell of cold weather poetically named the cold winds, threaten to slash the yields from the second rice crop of the season by 50%. These conditions frequently occur within the months of September and October. Rice breeders at the Guangdong Academy of Agricultural Science aim to develop new rice varieties that can withstand and thrive in the cold dew winds. Apart from records of average daily temperature, they lacked precise information on the severity of the conditions which the new varieties have to endure. The lack of data severely hampers the development of the new rice varieties. A monitoring solution was therefore required to further this research…
