Data logger DL200P

Environmental data logger with an expandable sensor system

DL200P data logger

Just like the DL200H this data logger, too, comes equipped with two internal sensors for the detection and documentation of air temperature, dew point and both relative and absolute humidity.

Moreover, the DL200P has additional connection options for up to four external measured value sensors, thus offering its users considerably enhanced fields of application.

The DL200P can be simultaneously fitted with two electrode pairs for measuring resistance dampness, as well as two TS910 contact temperature sensors.

Therefore, the DL200P can be used for the most varied monitoring tasks – also via LAN in the network using further DL data loggers – for example for silo surveillance and control of bulk goods, or for checking the temperature of water-based fluids.

Furthermore, all documentation can be completely collated for insurance or regress resistance for construction drying and water damage clearance. The practical alarm function also makes it possible to detect and avoid potential damages to buildings or inventory before they occur.

Definition of measurement channel – How many measured values can be recorded?

All devices from the DL series are powerful multi-channel data loggers with which you can not only detect, but also record all of the compatible measured values (see technical specifications).

The term "measurement channel" is not used to mean the same as it is by some of our competitors – meaning the available sensors, but instead – the same as in analysis software – it means one individually selectable "recording track", i.e. the value which should be logged.

For each measured value and measured unit (channel group), one or more of the four following types of measured values can be recorded: current, minimum, maximum or average. Each of these four values represents a measurement channel.

The maximum amount of available measurement channels for each data logger is thus the amount of detectable channel groups (e.g. temperature in °C) multiplied by the four types of measured values.

In total, 20 of these measurement channels can be freely selected for logging and three for being displayed. 

Many measurement channels –
many possibilities...

The data logger can detect up to 32 measurement channel groups of the most varied sensor signals. Then, it can record an individually configurable composition of measured values from up to 20 separate measurement channels in freely selected intervals.

Due to the wide range of possible applications, the instruments are perfectly suited for monitoring the environment of buildings, controlling climate sensitive production processes and storage conditions or even providing evidence when required.

The devices are fitted with LAN and USB interfaces by default to offer a quick transfer of data.

Pro software for configuring
and managing measured data

Each measuring device comes with pro software, which can be used to simultaneously read as many data loggers as the user likes – and when using LAN, they don't even need to be nearby.

In addition to the comfortable option for administering and configuring various data loggers, the software can also be used to create reports or to export recorded measured data for archiving.

Real-time data compilation
in a network

All data loggers of the DL series can be assigned an individual IP address – even in decentralised measuring networks with many various data loggers – allowing both the transmission of measured data and also device configuration via LAN.

One to two TS910 contact temperature sensors ➊ can be connected to the data logger via plug sockets ➋.

Moreover, one electrode pair for measuring resistance dampness can be attached to each of the two BNC connectors ➌ at the DL200P.

Pro software for configuring and managing measured data

Using the software included in the scope of delivery, all DL data loggers can conveniently be set up or configured for network operation. The measured data can simultaneously be read, analysed and exported by all data loggers – using LAN also from remote installation sites.

Now upgrade the standard software with the options MultiMeasure Studio Professional has to offer.

Since all DL models are fully compatible with this, the software is not only perfectly suited for the analysis of all measured data, but can also be used to calculate the dew point temperature or absolute humidity in retrospect, if it wasn't recorded already.

Finally one software for basically all measuring devices

Even owners of partially compatible or isolated measuring instruments can benefit from MultiMeasure Studio Professional: This software enables the analysis and administration of all measuring projects and customer data across multiple devices in a single application!

Using the unique report generating function you can create professional measurement reports in a trice:

Numerous boilerplate texts for building diagnostics, moisture measurement, leak detection and thermography are already included completely formulated.

All information about the "MultiMeasure Studio Professional" can be found here... 

Besides the standard anthracite colour, the data logger DL200P is optionally also available with a white or yellow housing.
