VEGACAP 67 Product Overview
VEGACAP 67 is a capacitive level switch launched by VEGA, mainly used for limit detection of liquids and solid bulk materials. Its robust mechanical structure and high reliability make it suitable for industries such as chemicals, petrochemicals, water treatment, and food.
The instrument detects whether the material has reached the set point through the principle of capacitance change, outputs a relay or transistor signal, and realizes pump control, alarm, or interlock functions.
Working Principle and Core Advantages
Capacitive Measurement Principle
The probe of VEGACAP 67 and the vessel wall form a capacitor. When the material covers the probe, the dielectric constant changes, and the capacitance value changes accordingly. The internal circuit of the instrument detects this change and triggers the switching action.
Main Technical Features
- High adaptability: Can measure liquids, granules, and powders, not limited by dielectric constant (adjustable).
- Rugged and durable: Stainless steel or PTFE-coated probe, corrosion-resistant and wear-resistant.
- Flexible installation: Supports multiple process connections such as threads and flanges.
- Easy commissioning: Zero point and span calibration can be completed via potentiometer or buttons.

Installation and Commissioning Points
Installation Steps
- Confirm that the process connection size matches the vessel interface, and install the sealing gasket.
- Insert the probe vertically or at an angle into the vessel to avoid material accumulation affecting detection.
- Tighten the process connection to ensure sealing without leakage.
- Connect the power supply and output signal cables according to the wiring diagram in the manual.
- After power-on, adjust the sensitivity potentiometer according to the dielectric constant of the material.
Commissioning Precautions
- In an empty vessel state, adjust the zero point so that the output is in the untriggered state.
- Cover the probe with material and adjust the span so that the output operates reliably.
- For adhesive materials, it is recommended to clean the probe regularly and choose a coated model.
- In explosion-proof locations, intrinsically safe or flameproof models must be selected and relevant regulations must be observed.
Selection and Procurement Recommendations
When purchasing VEGACAP 67, it is necessary to clarify the process connection, material, output type, and explosion-proof requirements. The table below provides common selection combinations to help make quick decisions.
| Application Scenario | Recommended Model Features |
|---|---|
| Water treatment, sewage | Stainless steel probe, relay output, IP67 |
| Chemical liquids | PTFE coating, explosion-proof Ex ia, transistor output |
| Food and beverage | Stainless steel 316L, hygienic connection, IP66 |
| Solid powders | Extended probe, wear-resistant coating, flange connection |

Frequently Asked Questions
Can VEGACAP 67 be used in explosion-proof areas?
Yes. VEGACAP 67 offers intrinsically safe (Ex ia) and flameproof (Ex d) options, suitable for gas and dust explosive atmospheres. For specific explosion-proof ratings, please refer to the explosion-proof certification chapter in the manual.
How to determine whether the probe needs cleaning?
If the switch operates with frequent false alarms or unstable output, it may be caused by material adhering to the probe. It is recommended to shut down, remove and inspect, and wipe with a soft cloth and neutral detergent.
