  • Page 3: Table Of Contents

    Information on TEDS is provided in every operating manual of HBM transducers supporting TEDS. For more information on the different mounting possibilities, please refer to the mounting instructions “TEDS memory module in connector” and “TEDS memory module in the transducer cable” at our Web site www.hbm.com/TEDS A1813-1.1 en...

  • Page 4: Safety Information

    General dangers of failing to follow the safety instructions The TEDS module is a state of the art unit and as such is failsafe. The module may give rise to dangers if it is inappropriately installed and operated by untrained personnel.
  • Page 5 TEDS CAUTION Symbol: Meaning: Potentially dangerous situation Warns of a potentially dangerous situation in which failure to comply with safety requirements could lead to damage to property and slight or moderate physical injury. NOTE Symbol: Means that important information about the product or its handling is being given.

  • Page 6: Field Of Application

    A special circuit (patent applied for) makes it possible to use the existing cable leads for transferring the TEDS data. This means that the same cables can be used as for transducers that do not have TEDS.

  • Page 7: The Contents Of The Teds Memory

    TEDS The contents of the TEDS memory The information in the TEDS memory is organized in table form. Only the entered values are stored in the TEDS memory itself. The amplifier firmware assigns the interpretation of the respective numerical values. This places a very low demand on the TEDS memory.
  • Page 8 • Administrator rights (ID level) Administrator rights in relation to TEDS are intended for the sensor manufacturer. In the case of a self-built sensor or subsequent upgrading with TEDS, HBM customers can of course also make use of these rights. A1813-1.1 en...

  • Page 9: Writing To Or Altering The Memory Contents

    If TEDS is referenced at HBM as a complete solution on new HBM transducers or as an expansion of existing transducers, data is already written to the TEDS memory so that the TEDS can be used immediately. This applies to both transducers with TEDS memory integrated in the transducer housing and those fitted with a TEDS module in the transducer connector or cable.

  • Page 10: Using The Teds-Editor

    Calling up the TEDS Editor presupposes that the transducer to be edited is recognized as the TEDS transducer by the higher level software. Call up the Editor by clicking on ”Edit TEDS” in the context menu, which can be opened by right clicking on the transducer.
  • Page 11 • Signal processing (HBM specific): Data regarding high or low pass filtering, tare or zero value. This data is optional, if no values are entered in TEDS, the respective settings of the amplifier are retained when reading in the TEDS data.

  • Page 12: Editing Teds In The Template View

    The Template view uses the definitions in the Standard IEEE 1451.4 and displays the entered values in the same way that they are stored in the TEDS memory. The main templates for use with HBM transducers are listed in the following chapter.

    Standard IEEE 1451.4 makes provision for other templates over and above those explained here. Most of these additional templates describe other transducer types. TEDS-enabled HBM amplifiers currently recognize the following templates from this group: High-Level Voltage Output Sensors Transducers with voltage output...
