Data logger of the latest V7 generation
The professional measuring instrument ALMEMO® 204 provides numerous outstanding functions for special applications using digital ALMEMO® D6 sensors and the latest ALMEMO® D7 sensors.
Four measuring inputs for all digital ALMEMO® D6 and D7 sensors
All new digital ALMEMO® D6 and D7 sensors for a wide variety of measurable variables can be connected and evaluated. ALMEMO® standard sensors with the DIGI measuring range can also be used, e.g. for crossflow turbines and high-voltage modules for thermocouples, and DC and AC voltages. The ALMEMO® 204 supports all ALMEMO® functions.
New digital ALMEMO® D7 sensors
With these digital ALMEMO® D7 sensors the ALMEMO® system is enhanced by many new functions and applications. ALMEMO® D7 sensors operate via an all-digital interface to the ALMEMO® 204 data logger ensuring high-speed serial transmission of all measured values. Each ALMEMO® D7 sensor has its own processor. They all work in parallel at their own sensor-specific sampling rate. D7 sensors thus attain very high measuring speeds in dynamic measuring operations.
Digitise and calibrate the existing sensor technology
Using the ALMEMO® V7 input plugs the existing sensor technology can easily be digitised. 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.
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.
One measuring instrument for every need
This compact, handy device can, as an option, be fitted with rubberised impact protection for mobile use. The latest energy saving technology ensures long operating times. For stationary applications a H-rail mounting is available.
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 soft-keys and a cursor block. The menu guidance is clearly structured and easy to understand. Users can even configure their own customised user menus from a range of 50 different parameters to display exactly those parameters required by a particular application. Choice of languages: German, English, French.
End-to-end programming of all parameters for ALMEMO® D6 and D7 sensors
The ALMEMO® 204 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 two ALMEMO® output sockets can be used to connect a PC / network and an ALMEMO® output interface with relays and analogue output at the same time. With option KL it is possible – for a digital ALMEMO® sensor (i.a. ALMEMO® D6 / D7 temperature or pressure sensors) to program multi-point adjustment or linearisation in the ALMEMO® plug itself.
ALMEMO® devices can be used for a variety of applications, examples:
Monitoring the indoor climate conditions: temperature, air humidity, CO2 level, air flow.
Measuring the illumination and the UV exposure at the workplace: illuminance in lux, UV index.
Mobile measurements in ventilation systems: air velocity, temperature, air humidity.
Meteorological station with meteo multi sensor and radiation sensors: air velocity, wind direction, temperature, air humidity, atmospheric pressure, global radiation, UV radiation, UV index.
Monitoring temperatures in test stands and in industrial processes: temperature, non-contact measurement (infrared sensor).
Mobile test measurement in heating furnaces and climatic chambers: temperature, air humidity, dew point, absolute humidity.
Measuring the quality of deionized process water (ultrapure water): electrical conductivity in the lower range of few μS/cm.
Test measurement of process water and waste water in industry (i.a. chemistry, pharmacy, paper, food): pH value, redox value, electrical conductivity, temperature.
Test measurements in compressed air systems: fast pressure measurement (up to 500 mops), dew point measurement (residual moisture).
Measuring AC and DC voltage signals with high galvanic isolation: voltage/power/output DC (up to 1000 mops), true RMS value AC
