    The SITRANS LC500 variable frequency oscillator The SITRANS LC500 probe is equipped with a variable frequency oscillator which responds to the capacitance: a change in capacitance is registered as a change in frequency. The relationship between capacitance and frequency is inverse, resulting in high resolution and accuracy.
  • Page 16 As the product level rises the capacitance will increase. Non-conductive or conductive contents In practice, the SITRANS LC500 probe is usually insulated. If the vessel contents are non- conductive, the dielectric is composed of the vessel contents and the insulation, and the separation distance is from the probe to the tank wall.

  • Page 17: The Sitrans Lc500 Electrode

    The SITRANS LC500 electrode The SITRANS LC500 electrode, comprising a measurement section and an active shield section, is the primary sensor of the system. It supplies the electrical capacitance value of the measurement section relative to the environment (tank wall or stilling well).
  • Page 18 This increases the achievable resolution of the measurement, since any change in level will be greater relative to the length of the measurement section. Page 12 SITRANS LC500 – OPERATING INSTRUCTIONS 7ML19985GE04...

  • Page 19: Application: Sitrans Lc500

    The entire SITRANS LC500 transmitter is potted in epoxy resin as part of the intrinsic safety protection. The potting also protects the electronics against mechanical vibration and moisture influences. The transmitter is connected to the electrode by a mini coaxial cable, and grounded to a connection point inside the enclosure.

    The LCD displays the value as mA, or pF, or percent, depending on the setting for the transmitter variable (TV). If you are using HART, you have the option to define the units. Page 14 SITRANS LC500 – OPERATING INSTRUCTIONS 7ML19985GE04...

  • Page 23: Probe Configuration

    SITRANS LC500 Electrode (Probe) Characteristics Apply to all general connection configurations: • The standard SITRANS LC500 insulated electrode is designed for use in both conducting and non-conducting liquid applications. • Most electrodes consist of an active shield portion and a measurement portion, which combine to form the complete electrode.

  • Page 24: Electrode Assembly

    Any standard process connection is available with the SITRANS LC500, and special versions can be fabricated to match the mounting and application requirements. A wide range of threaded and flanged fittings is available. (Contact your local Siemens Milltronics representative for details, or check our website at: www.siemens-milltronics.com.)

  • Page 25: Pressure And Temperature Considerations

    Enamel probes are recommended when the process temperature exceeds 200 C, and/or in combination with very high pressure. Note: Consult your Siemens Milltronics representative if the material to be measured may be incompatible with the SITRANS LC500 materials of construction.

    The loop-circuit will withstand voltages up to 250 Vac/Vdc without any damage. The SITRANS LC500 uses a switched power supply circuit, which makes the most efficient use of the available power present on the terminals. If the signal current is low,...

  • Page 31: Cable

    For a multi-drop application, where the measuring supply is fixed to 4 mA, the voltage on the terminals of the SITRANS LC500 should be at least 12 Volts. The loop circuit is completely isolated from the measurement circuit. It is designed so that the internal capacitance and inductance on the terminals are isolated and do not factor in safety calculations.
  • Page 32 With three devices, at 3 x 68 nF, the allowable cable length will be considerably limited. Notes: • If the device is part of a multi-drop setup, the SITRANS LC500 sets the current to 4 mA, which inhibits analog signalling, including fault signalling. •...

  • Page 33: Terminals

    Terminals The SITRANS LC500 is equipped with two terminal blocks, both insensitive to polarity. One terminal block is intended for connecting the instrument cable (loop power). The other terminal block provides the solid-state switch output. Connecting SITRANS LC500 The processor integrated circuit is covered by a label which contains product information and which also acts as a protective seal against moisture.

  • Page 38: Cathodically Protected Metal Tanks

    Safety Grounding The safety grounding requirements are determined by the application and the connected instruments. The SITRANS LC500 transmitter does not have any special requirements due to the galvanic separation between the measurement section and the loop section. Depending on the DCS characteristics, there are three possible grounding options: Page 32 SITRANS LC500 –...

  • Page 40: Communications

    The internal diagnostic functions continuously monitor the operation of the transmitter. An error signal is generated if a failure or irregularity occurs. The SITRANS LC500 sends the signal current according to the NAMUR NE 43 recommendation. During normal operation the current remains within the range from 3.8 to 20.5 mA.

  • Page 54: Calibration Using Hart

    Calibration using HART The SITRANS LC500 transmitter can be calibrated using HART, with a HART communicator ; a laptop running Simatic PDM, or with the Host system (DCS). The local circumstances determine the manner in which calibration takes place. If the circumstances allow the product to be brought to the 0% and 100% point level, calibration is simple.

    Test function Auto Self-testing SITRANS LC500 continuously performs a variety of tests to verify that the device is functioning correctly. These include a test where a known capacitor is applied to the input of the device. The internal results must match the known capacitance value. If a deviation is detected the Fault/Failure can be flagged with a pre-set loop-current (user configurable) and as a status in each HART message.

    For instruments without a stilling well, the 0% setting needs to be calibrated after the device is installed, and with the tank/vessel empty. Calibration is also sometimes neces- sary after installing a SITRANS LC500 fitted with a stilling well, although in most cases the 0% setting is calibrated at the factory.
