VEGACAP 35 Product Overview

VEGACAP 35 is a capacitive level switch launched by VEGA, mainly used for point level detection of liquids and bulk solids. Based on the capacitive measuring principle, the instrument determines whether the material has reached the set level by detecting changes in capacitance between the probe and the vessel wall.

VEGACAP 35 is compact in structure and easy to install, and is widely used in level alarm and pump control scenarios in chemical, water treatment, food, building materials and other industries. This article provides a download for the VEGACAP 35 Chinese manual and systematically summarizes its technical points and selection methods.

Working Principle and Core Advantages

Capacitive Measuring Principle

The probe of VEGACAP 35 and the vessel wall form a capacitor. When the material rises and covers the probe, the dielectric constant changes, and the capacitance changes accordingly, based on which the instrument outputs a switching signal.

This principle is not affected by medium density or viscosity, making it suitable for various complex working conditions. For conductive media, the probe insulation layer can effectively isolate and ensure stable measurement.

Main Technical Advantages

  • Reliable measurement: not affected by foam, buildup, or turbulence, with strong adaptability.
  • Flexible installation: supports various process connections such as threads and flanges, and can be installed horizontally or vertically.
  • Easy commissioning: zero point and span can be set via potentiometer or buttons.
  • Wide application range: suitable for liquids, slurries, granules, and powdered solids.

Installation and Commissioning Points

Installation Precautions

  • The probe should avoid the inlet to prevent false actuation caused by direct material impact.
  • For horizontal installation, the probe should be tilted downward about 15° to avoid buildup.
  • The vessel wall must maintain sufficient distance from the probe to prevent capacitive coupling interference.
  • For viscous media, it is recommended to choose a probe model with an insulation layer.

Commissioning Steps

  1. Confirm that the supply voltage matches the instrument nameplate, then connect the power supply.
  2. In an empty vessel, adjust the zero potentiometer so that the output is in the "uncovered" state.
  3. Fill the vessel with material up to the probe position, adjust the span potentiometer so that the output switches to the "covered" state.
  4. Raise and lower the level repeatedly to verify whether the switching point is accurate.
  5. Lock the potentiometer, record the commissioning parameters, and complete commissioning.

Selection and Procurement Recommendations

When purchasing VEGACAP 35, it is necessary to confirm process connection, process temperature, process pressure, medium characteristics, and output mode. For corrosive media, probes and seals made of corresponding materials should be selected.

Before procurement, it is recommended to obtain the VEGACAP 35 Chinese manual and selection catalog, check the instrument model code, and ensure it matches the on-site working conditions. If explosion-proof requirements exist, the explosion-proof certification level must also be confirmed.

Frequently Asked Questions

What media is VEGACAP 35 suitable for?

It is suitable for liquids, slurries, granules, and powdered solids, especially for media with stable dielectric constants. For materials with low dielectric constants, a high-sensitivity model should be selected.

What should I do if the instrument output frequently malfunctions?

Check whether the probe has buildup, whether the installation position is close to the inlet, and recalibrate the zero point and span. If necessary, adjust the sensitivity or change the installation point.
