What is VEGACAL 64?
VEGACAL 64 is a capacitive level switch launched by VEGA, mainly used for limit detection of liquids and bulk solids. It determines whether the probe is covered by the medium through capacitance changes, thereby outputting a switching signal.
This instrument is suitable for process vessels in the chemical, petrochemical, water treatment, and food industries, and can perform high-level, low-level alarms, or pump control interlocking. For working conditions requiring reliable limit protection, VEGACAL 64 is a common choice.

It is recommended that engineers and procurement personnel read the manual thoroughly before selection and installation to confirm that the process connection, power supply method, and output type are consistent with the site.
Core Measurement Principle
Capacitive Limit Detection
The probe of VEGACAL 64 and the vessel wall form the two plates of a capacitor. When the medium rises and contacts the probe, the dielectric constant changes, and the capacitance changes accordingly.
The built-in electronic module detects this capacitance change and triggers the switch output when the set threshold is reached. This principle does not depend on medium movement, so it is suitable for viscous, easily scaling, or particle-containing media.
Applicable Media and Limitations
- Applicable: water-based liquids, oils, acid and alkali solutions, powders, granular solids.
- Note: Media with too low dielectric constant (such as some hydrocarbons) require confirmation of sensitivity.
- Note: Strongly conductive media require a probe version with an insulating coating.

Installation and Commissioning Points
Installation Position
- Avoid the inlet and agitator to prevent the probe from impact or false triggering.
- The probe should extend into the vessel to ensure it can contact the target liquid level or material level.
- For side mounting, pay attention to the probe length and distance from the vessel wall to avoid interference from material buildup.
Commissioning Steps
- Confirm the supply voltage and wiring terminals, and connect according to the wiring diagram in the manual.
- Perform zero calibration (empty calibration) in an empty vessel.
- Fill to the target position and perform full-scale calibration (full calibration).
- Observe whether the switch action is consistent with the liquid level, and fine-tune the sensitivity if necessary.
Key reminder: Before commissioning, be sure to confirm that the vessel has been depressurized and emptied, and comply with on-site safety regulations.
Selection and Procurement Recommendations
- First confirm the medium name, dielectric constant, temperature, pressure, and corrosiveness.
- Select relay, transistor, or two-wire electronic module according to output requirements.
- Confirm the process connection specifications and materials to avoid on-site installation failure.
- When purchasing, request the VEGACAL 64 Chinese manual and certificate of conformity for acceptance and subsequent maintenance.
FAQ
What to do if the switch malfunctions?
Common causes include material buildup, improper sensitivity setting, or poor grounding. It is recommended to clean the probe, recalibrate, and check vessel grounding.
Can it be used for conductive media?
Yes, but a probe version with an insulating coating must be selected and set according to the manual requirements.
