  • Page 8: Principle Of Operation

    In addition to the type label outside, you can also find the serial num- ber on the inside of the instrument. Principle of operation Area of application VEGACAL 65 is a level sensor with partly insulated probe for continu- ous level measurement. The electronics functions according to the admittance principle (phase-selective admittance processing). It is designed for industrial use in all areas of process technology and can be applied in all areas of industrial process measurement.

  • Page 12: Mounting

    Fig. 4: Measures against moisture penetration Pressure/Vacuum The process fitting must be sealed if there is gauge or low pressure in the vessel. Before use, check if the seal material is resistant against the measured product and the process temperature. VEGACAL 65 • Foundation Fieldbus...

  • Page 13: Mounting Instructions

    During operation, the probe must not touch any installations or the vessel wall. The measured value can also change if the distance to the vessel wall changes considerably. If necessary, secure the end of the probe (insulated). In the gravity weight there is a thread (M12), e.g. for a ring bolt (article no. 2.27424). The thread is already insulated in the gravity weight with an adapter. Make sure that the probe cable is not completely taut. Avoid tensile loads on the cable. VEGACAL 65 • Foundation Fieldbus...
  • Page 14 If the instrument is mounted in the filling stream, unwanted false measurement signals can be generated. For this reason, mount the instrument at a position in the vessel where no disturbances, e.g. from filling openings, agitators, etc., can occur. This applies particularly to instrument versions with a longer probe. Fig. 6: Inflowing medium VEGACAL 65 • Foundation Fieldbus...

  • Page 15: Connecting To Power Supply

    • Connect only in the complete absence of line voltage • If overvoltage surges are expected, overvoltage arresters should be installed according to Foundation Fieldbus specification Tip: We recommend VEGA overvoltage arrester B63-32. In hazardous areas you must take note of the respective regulations, conformity and type approval certificates of the sensors and power supply units. Voltage supply The instrument requires a operating voltage of 9 … 32 V DC. Operat- ing voltage and the digital bus signal are carried on the same two-wire connection cable.
