Dataloggers
In almost all industries, the acquisition of measurement data and its analysis form the basis for a wide range of optimization and decision-making processes. Dataloggers collect and save the data required for this. These are versatile, powerful, yet inexpensive data acquisition devices that process analog, digital, and other types of variables at high speed and resolution. Whether you want to save the measurement data from temperature-, humidity-, or force sensors, our dataloggers offer the best way to do this.
Models:
- Industrial multichannel datalogger
- WLAN datalogger
- 3G / 2G multi-channel datalogger
- Micro datalogger for temperature and humidity
- USB temperature datalogger
- Micro datalogger for analog signals
Specifications:
Inputs / outputs and interfaces:
- Universal analog input channels (thermocouples, V, mV, mA, Pt100 and Pt1000)
- Digital I/Os (individually configurable as input or output)

- Chemicals, oil & gas
- Textiles
- Energy
- Agriculture
- Mining
Dataloggers consist of a programmable microprocessor, one or more cables for connecting the data source, at least one interface, and a storage medium. The data is recorded internally or externally via a manufacturer-dependent interface.
The following interfaces allow the data to be integrated into a controller and transmitted over a large range. The most common interface variants in the industrial and machine sectors are:
- RS232
- RS485
- CAN
- USB
- Ethernet
Any external sensors, devices or machines can be connected as data suppliers via connections like USB, Bluetooth, WLAN, D-Sub, or industrial terminals. These forms of access usually also make it possible to configure the datalogger for an area of application. Depending on the desired measured variable, dataloggers have one or more channels in order to be able to connect several sensors to them at the same time. The storage rhythm depends on the specific use. The storage process always takes place fully automatically at precise time intervals, or at the moment of data generation.
The datalogger presented here has configurable analog inputs that can be used for thermocouples, resistance thermometers based on Pt100 and Pt1000, as well as voltage and current signals. In addition, two relay outputs and eight digital ports can be configured individually as inputs or outputs. Up to 128 math channels are available for operations on the measured values. In addition, the datalogger can recognize up to 32 alarm events and send corresponding output activations, e-mails and SNMP traps.
The RS485 interface of the datalogger can be operated as a Modbus RTU master or slave. As a master, it can read and log up to 64 external channels. A 10/100 MBps ethernet interface enables access via browser (HTTP), FTP (server and client), SNMP, sending e-mails (SMTP) and Modbus TCP. The 512K basic logging memory used for data storage can be expanded using an SD card. An exclusive color HMI can also be connected or installed remotely for local display or configuration.
