  • Page 4: Almemo ® D7 Digital Sensors

    ALMEMO D7 digital sensors ® The latest ALMEMO D7 digital sensors have been designed to overcome all the limita- ® tions experienced with earlier sensors regarding measurable variables, speed, range of measured values, and number of channels per sensor. It is also possible to perform effi - cient measuring operations simultaneously using high-speed and low-speed sensors with any range of measured values.

    errors. To ensure the highest possible level of accuracy these D6 sensors are fitted as standard with an atmospheric pressure sensor; this is always used automatically for atmo- spheric pressure compensation (PC) - even if the particular channel is not activated. The atmospheric pressure is programmed by default as a climate variable and can thus be configured as reference function (s.6.3.6);...

    2.D7 UI connectors ZED700-FS, ZED701-FS, ZED702-FS D7 connectors are used, depending on connector type, to record voltages and currents in three different variants and each of these at two rates; they do so by means of an integrated 24-bit delta-sigma A/D converter. At five measuring operations per second (mops) 200,000 digits can be acquired or at 500 mops, 20,000 digits.

  • Page 10: D7 Bridge Connector Zkd700-Fs

    5.D7 bridge connector ZKD700-FS D7 bridge connector ZKD700-FS is used to record the output voltage of a 4-wire full bridge with a 5V supply (5V, Gnd); it does so by means of an integrated high-speed 24- bit A/D converter. It is thus possible to record dynamic changes in force by means of wire strain gauges at two different conversion rates, namely 10 or 1000 measuring opera- tions per second.

  • Page 11: Sensor Adjustment And Scaling

    5.2.Sensor adjustment and scaling These two quantities offer two different conversion rates and thus also different measuring ranges and resolutions. It is important to strictly adhere to each of the maximum final valu- es including the decimal point. For the purpose of zero adjustment the 'ZERO' key is provided. For configuring the sensor's individual gain and scaling there are two possible procedures.

    8.D7 conductivity probe FYD741LF 8.1.Basic principles The conductivity (unit S/m = Siemens/meter) is a measure for the ion concentration in a measuring solution. Conductivity is proportio- nal to the amount of salt, acid, or base alkaline content measured in the solution, High-purity water has a conductivity of approx.

    8.2.Measuring principle The conductivity in electrolytes is obtained via an electro-chemical resistance measure- ment using a 4-electrode measuring cell. An AC voltage with a frequency of approx. 1 kHz is applied to the electrodes. The current flowing through the test object is conver - ted into a voltage.
