VEGACAP 64 Product Overview
VEGACAP 64 is a capacitive level switch launched by VEGA, mainly used for limit detection of liquids and bulk solids. This instrument uses the capacitive measurement principle and determines whether the material has reached the set limit by the change in capacitance between the probe and the container wall. VEGACAP 64 has a robust structure and is suitable for various industrial occasions, making it a classic model among level switches.

Working Principle and Technical Features
Capacitive Measurement Principle
The probe of VEGACAP 64 and the container wall form the two plates of a capacitor. When the material rises and covers the probe, the dielectric constant changes, causing the capacitance value to change. The internal circuit of the instrument detects this change and outputs a switching signal to achieve limit alarm or control.
Main Technical Features
- Wide application range: Can measure liquids, granular and powdery bulk solids.
- Pressure and temperature resistance: Process pressure up to 64 bar, process temperature up to 200°C.
- Multiple outputs: Provides relay, transistor, and two-wire output modes.
- High protection rating: Standard IP66/IP67, optional IP68.
- Various materials: Probe can be made of stainless steel, PTFE, PFA, etc., adapting to corrosive media.

Installation and Commissioning Points
Installation Steps
- Confirm that the process connection size matches the container interface, and prepare the sealing gasket.
- Install VEGACAP 64 vertically or horizontally on the top or side wall of the container, ensuring the probe extends into the container.
- Tighten the process connection, being careful not to use excessive force to avoid damaging the probe insulation layer.
- Connect the power supply and output signal wires according to the wiring diagram in the manual, paying attention to polarity.
- After power-on, use the commissioning tool or buttons to perform empty tank and full tank calibration.
Commissioning Precautions
- Before calibration, ensure that the material in the container is in a known state (empty or full).
- For adhesive media, it is recommended to clean the probe regularly to avoid false alarms.
- When used in hazardous areas, intrinsically safe models must be selected and explosion-proof regulations must be followed.
Selection and Procurement Suggestions
When selecting, it is necessary to clarify the medium characteristics (dielectric constant, corrosiveness, adhesion), process conditions (pressure, temperature), and output requirements. For media with low dielectric constant, it is recommended to use a probe with an insulating layer. When purchasing, please check the model code and request the VEGACAP 64 Chinese manual to ensure correct installation and use.
FAQ
What media is VEGACAP 64 suitable for?
