VEGACAL 67 Product Overview
VEGACAL 67 adopts the capacitive measurement principle, detecting level through changes in capacitance between the probe and the vessel wall. This instrument is suitable for various working conditions, including high temperature, high pressure, and corrosive media, making it a reliable choice in industrial level measurement.
Main Application Areas
- Chemical industry: level measurement of reactors and storage tanks
- Petroleum industry: oil-water interface, crude oil storage tanks
- Water treatment: level monitoring of sewage and clean water tanks
- Food and pharmaceutical: level detection in hygienic applications
- Building materials and metallurgy: level measurement of powders and granular materials
Working Principle and Technical Advantages
VEGACAL 67 is based on the capacitive measurement principle. The probe acts as one plate of a capacitor, and the vessel wall acts as the other plate. When the material covers the probe, the change in dielectric constant causes a change in capacitance, and the instrument converts the capacitance change into a level signal output.
Core Advantages
- High-precision measurement: suitable for media with various dielectric constants
- Strong adaptability: can measure liquids, solids, and interfaces
- High temperature and pressure resistance: process temperature up to 200°C, pressure up to 40 bar
- Multiple outputs: 4…20 mA/HART, PROFIBUS PA, Foundation Fieldbus
- Easy installation: multiple process connections and probe materials available

Installation and Commissioning Points
Correct installation and commissioning are key to ensuring the measurement accuracy of VEGACAL 67. The following steps can help you quickly complete instrument commissioning.
Installation Steps
- Confirm that the vessel opening size matches the process connection.
- Install the probe vertically on the top or side of the vessel, avoiding contact with the vessel wall.
- Ensure the probe extends fully into the vessel and is not subjected to feed impact.
- Tighten the process connection to ensure sealing.
- Connect the power and signal cables, paying attention to polarity.
Commissioning Points
- Empty tank calibration: perform zero calibration when the vessel is empty.
- Full tank calibration: perform full-scale calibration when the vessel is full.
- Dielectric constant setting: adjust instrument parameters according to the dielectric constant of the medium.
- Output verification: check whether the 4…20 mA output corresponds to the level.
Selection and Procurement Recommendations
During selection, it is necessary to comprehensively consider medium characteristics, process conditions, and installation environment. It is recommended to confirm the specific model with a VEGA authorized distributor or technical personnel.
Key Selection Factors
- Medium dielectric constant: low dielectric constant media require high-sensitivity probes.
- Process temperature and pressure: ensure the instrument rating covers the working conditions.
- Probe material: corrosive media require PTFE or PFA coating.
- Output signal: select according to the control system interface.
- Explosion-proof requirements: hazardous areas require intrinsically safe or flameproof types.
