VEGACAL 69 Product Overview
VEGACAL 69 is a capacitive level transmitter launched by VEGA, specifically designed for continuous level measurement of liquids and bulk solids. The instrument uses the capacitive measurement principle, detecting the level height through the capacitance change between the probe and the vessel wall.
VEGACAL 69 is suitable for high-temperature, high-pressure, and corrosive working conditions, and is widely used in industries such as chemicals, petroleum, water treatment, and food. Its rugged construction and stable measurement performance make it a reliable choice for industrial level measurement.

Selection Considerations
- Medium characteristics: The dielectric constant must be greater than 1.5. For low dielectric constant media, a probe with an insulating layer should be selected.
- Process connection: Select threaded, flanged, or sanitary connections according to the vessel interface.
- Environmental conditions: For high-temperature, high-pressure, or corrosive working conditions, select corresponding materials and protection ratings.
- Output requirements: When remote monitoring is required, select HART protocol or 4…20 mA output.
Installation and Commissioning Steps
Installation Steps
- Confirm that the vessel has been depressurized and emptied to ensure installation safety.
- According to the manual requirements, install the VEGACAL 69 at the specified position on the vessel, ensuring that the probe remains parallel to the vessel wall.
- Tighten the process connection to ensure reliable sealing and prevent leakage.
- Connect the power supply and signal cables, paying attention to polarity and shielded grounding.
Commissioning Points
- After power-on, use the display module or HART handheld communicator to set parameters.
- Perform zero calibration when the tank is empty and full-scale calibration when the tank is full.
- Adjust the sensitivity according to the medium characteristics to ensure stable measurement.
- After commissioning is completed, record the parameters and lock the settings to prevent misoperation.
Common Problems and Maintenance
Common Problems
- Fluctuating measured value: Check whether the probe has buildup and whether grounding is good.
- No signal output: Check the power supply and wiring, and confirm whether the fuse is blown.
- Large measurement deviation: Recalibrate zero and full scale, and confirm whether the dielectric constant has changed.
Routine Maintenance
- Regularly check the probe for corrosion, wear, or deposits, and clean it if necessary.
- Perform calibration verification every six months to one year.
- Check whether the process connection is loose to ensure the seal is intact.
Following the above guidelines can effectively extend the service life of the VEGACAL 69 and ensure measurement accuracy. For more information, please download the complete Chinese manual.
