ALMEMO® Measuring Instruments The ALMEMO® system The ALMEMO® system comprises an ALMEMO® measuring instrument and intelligent ALMEMO® connectors for the relevant sensor equipment. An extensive range of measuring instrument variants is thus available from the single-channel transmitter right through to data acquisition systems with over 1000 measuring points. The only differences between most of the measuring instruments in the ALMEMO® series concern their housing (i.e. handheld instruments, desktop instruments, 19inch systems, fitted panel instruments, transmitters, etc.), the number of...

ALMEMO® Measuring Instruments ALMEMO® measuring instruments are real individuals ALMEMO® instruments automatically recognize the specifications of a sensor as it is connected. Specific functions will only be activated as and when the appropriate connector, interface cable, or module is detected. With humidity sensors the dew point, mixture ratio, vapor pressure, and enthalpy will be calculated automa- tically. Measuring operations involving psychrometers, dynamic pressure probes, or probes for solute oxygen may require pressure compensation; for this purpose the prevailing atmospheric...

ALMEMO® Measuring Instruments Input connector ALMEMO® input connector, also for existing sensors, see chapter ALMEMO® input connectors ALMEMO® standard plug • The ALMEMO® measuring system makes it possible to process four channels per measuring input – depending on the sensor and the measuring instrument. • The ALMEMO® plug incorporates 6 screw terminals - 2 for the sensor‘s power supply and 4 for its measuring signal. • With Pt100 sensors using 4-conductor circuitry all 4 free connections will be required for the measuring signal. Only one sensor of this type can be connected therefore per...
