Ahlborn Almemo MA104

Data logger ALMEMO® 104 for all sensors, 4 measuring inputs ALMEMO ® data logger and precision measuring instrument, latest V7 generation Comprehensive range of functions for all application areas Increased measuring accuracy, fast measuring rate 4 measuring inputs

Data logger of the latest V7 generation

The professional measuring instrument ALMEMO® 104 provides numerous outstanding functions for special applications using all ALMEMO® sensors (analog, DIGI, ALMEMO® D6) and the latest ALMEMO® D7 sensors.

Digitize and calibrate the existing sensor technology

Using the ALMEMO® D7 input plugs the existing sensor technology can easily be digitized. For digital sensors the overall accuracy of the measurement is independent from the ALMEMO® V7 display device / data logger. The complete measuring chain, consisting of sensor and connected ALMEMO® D7 measurement plug, can be calibrated. The accuracy during the calibration process can be increased by using multi-point adjustment.

One measuring instrument for every need

This compact, handy device can, as an option, be fitted with rubberized impact protection with mounting bracket for mobile use. For stationary applications H-rail or magnetic mounting are available.

Data logger for all storage applications

To save measured values a large flash memory is integrated. For monitoring tasks it can also be configured as a ring memory. For larger amounts of data, an external memory is available featuring a plug-in SD card. For autonomous long-term monitoring the data logger can also be run in energy-saving sleep mode.

Measuring inputs for ALMEMO® sensors, all generations

Data logger ALMEMO® 104 incorporates 4 measuring inputs. All new and already existing sensors designed for any measurable variable can be connected and evaluated. Sensors using analog signals pass via the integrated high-speed, high-resolution A/D converter. Additional electrical isolation between measuring inputs and power supply (device ground) increases measuring quality. Digital D6 and the latest digital D7 sensors transfer measured values to the measuring instrument directly in digital form.

New digital ALMEMO® D7 sensors

With these digital ALMEMO® D7 sensors the ALMEMO® system is enhanced by many new functions. They operate via an all-digital interface to the ALMEMO® 104 measuring instrument ensuring high-speed serial transmission of all measured values. The measuring ranges of ALMEMO® D7 plugs are independent of the measuring instrument and can be expanded as and when required for new applications. Measured values can be displayed with up to 8 digits (depending on range) and the units with up to 6 characters. Sensor designation and information can be up to 20 characters. The ALMEMO® D7 sensor has its own processor. These all work in parallel at their sensor-specific sampling rate. Scanning times on the ALMEMO® 104 can be set individually for quick-acting and slow-acting sensors. The ALMEMO® D7 plug can process up to 10 channels for measured values and function values. This includes new applications, especially for multi-purpose sensors (e.g. Meteo sensors) and for linking up to complex third-party devices (e.g. chemical analysers, power analysers).

Bright graphics display, easy and convenient operation by means of soft-keys

The white, illuminated graphics display ensures that functions and measured values can be viewed in the clearest way possible. The device is easy and convenient to operate by means of 4 softkeys and a cursor block. The menu guidance is clearly structured and easy to understand. The sensor display shows the measured values together with all relevant sensor-specific functions, e.g. temperature compensation, atmospheric pressure compensation. Measured values, peak values, average values, and limit values can all be displayed in easy-to-understand lists. Choice of languages: German, English, French.

End-to-end programming of all parameters for ALMEMO® D6 and D7 sensors

The ALMEMO® 104 professional measuring instrument provides a programming menu for the end-to-end programming of all the parameters needed for digital ALMEMO® D6 and D7 sensors. The required measuring ranges are selected (with ALMEMO® D7 sensors up to 10 measuring channels) and other relevant sensor parameters are configured, e.g. moving average, atmospheric pressure compensation, temperature compensation.

Other equipment

The two ALMEMO® output sockets can be used to connect a PC / network and an ALMEMO® output interface with relays and analog output at the same time. With option KL it is possible - for an ALMEMO® sensor (i.a. temperature or pressure sensors) to program multi-point adjustment or linearization in the ALMEMO® plug itself. This option is possible with all ALMEMO® plug versions. Standard connector (analog or DIGI), ALMEMO® D6 and D7 plugs.
