  • Page 8 Introduction Measuring Ranges There are corresponding measuring ranges for sensors with a non-linear characteristic such as 10 thermocouple types, Ntc and Pt100 sensors, infrared sensors, and flow sensors (rotating vanes, thermoanemometers, pitot tubes). Humidity sensors are available with function channels that also calculate humidity data such as dew point, mixture ratio, vapour pressure and enthalpy.
  • Page 9 Introduction Limit Values and Alarm Two limit values (1 max and 1 min) can be set for each meas. channel. An alarm value printout can be performed if a limit value is exceeded and, by means of relay output modules, alarm contacts are provided that can be individually allocated to limit values.
  • Page 10 Introduction Average Value of a Channel A manual averaging over a particular period or over single measurements is available for the selected channel. For the purposes of measuring the volume flow, the channel diameter or cross-section can be specified. PROCESS FLOW PROGRAMMING A cyclic measuring point scan with a time-based process flow control is required to register the measuring data of all connected sensors.
  • Page 11 Introduction Card can be used as storage device. The programming is saved with each change of the configuration. The output can be carried out via the display or the interface. It is possible to specify a selection according to a time interval, number or alarm value. Numbering of Measurements By entering a number, single scans or entire series of measurements can be identified and selectively read out from the memory.

  • Page 14: External Power Supply (Option U)

    Power Supply Tips regarding the correct handling of rechargeable batteries: In most cases, the batteries supplied are not charged when delivered! If NiMH cells are only partly discharged, the full capacity cannot be reached by a normal recharging. Therefore,use the device until the batteries are nearly totally discharged. Completely recharge the batteries afterwards.

  • Page 15: Data Buffering

    Power Supply 3.5 Data Buffering To ensure an uninterruptible power supply (UPS) for the real-time clock and the memory, a rechargeable lithium battery (3 V) is installed; this ensures that, in the event of the mains supply being interrupted, the date and time-of-day and all stored values over several years are saved.

  • Page 16: Connection Of The Transducers

    Connection of the Transducers 4. CONNECTION OF THE TRANSDUCERS ® ® Any ALMEMO sensors can be connected to the ALMEMO input sockets Mxx of the plug-in modules (8) and (9). For connecting existing sensors it is only ® necessary to connect a corresponding ALMEMO connector.
  • Page 17 Connection of the Transducers The analog inputs are electrically isolated by using photovoltaic relays and a potential difference of 50V DC or 60V AC, at maximum, is permissible between them. However, sensors combined within one connector and sensors with an own power supply are electrically connected to each other and must, therefore, be operated in isolation.
