Product Overview
VEGACAP 69 is a capacitive level switch launched by VEGA, used for limit detection of liquids and solids. Its robust mechanical structure makes it suitable for high-temperature, high-pressure, and corrosive working conditions.
The instrument detects whether the material has reached the set position through the principle of capacitance change, and outputs a reliable switching signal. It is widely used in the chemical, petroleum, water treatment, and food industries.
Main Features
- High reliability: Not affected by changes in medium conductivity or dielectric constant (some models require calibration).
- Temperature and pressure resistance: Process temperature up to +400°C, pressure up to 160 bar.
- Multiple materials: Probes can be made of PTFE, PFA, 316L stainless steel, etc., adapting to corrosive media.
- Flexible installation: Supports threaded, flanged, and other process connections.
- Output options: Relay, transistor, NAMUR, and other signal outputs.

Installation Guide
Correct installation is the key to ensuring the long-term stable operation of the VEGACAP 69. The following steps apply to most standard working conditions.
- Determine the installation position: Avoid areas with material impact, vortices, and strong vibration. For solid materials, it is recommended to install on the side wall or top of the silo.
- Check the process connection: Confirm that the thread or flange specifications match the on-site interface, and select a suitable gasket.
- Screw in or tighten: Use appropriate tools to avoid over-tightening and damaging the probe. For threaded connections, it is recommended to use sealant.
- Electrical connection: Connect the power supply and output signal according to the wiring diagram in the manual, paying attention to grounding and shielding.
- Commissioning and calibration: Perform zero calibration when the silo is empty, and full-scale calibration when the silo is full (for conductive media, adjust according to the instructions).
Installation Precautions
- The probe length should be greater than the possible buildup thickness to avoid false alarms.
- For adhesive media, it is recommended to use a probe with a shielded section or clean it regularly.
- In explosive hazardous areas, intrinsically safe or flameproof models must be selected and relevant regulations must be followed.
- After installation, check whether the instrument is secure to prevent loosening due to vibration.
Commissioning and Maintenance
The VEGACAP 69 is usually maintenance-free, but regular inspections can extend its service life. During commissioning, it can be adjusted via the potentiometer on the instrument or an external programmer.
- Daily inspection: Observe whether the output signal is normal, and whether the probe is damaged or has severe buildup.
- Cleaning: After power off, wipe the probe with a soft cloth and neutral detergent, avoiding scratching the insulation layer.
- Troubleshooting: If the signal is abnormal, first check the power supply and wiring, then recalibrate. Replace the electronic module if necessary.
Selection Points
When selecting, it is necessary to comprehensively consider the medium characteristics, process conditions, and output requirements. The following are key decision factors.
- Medium conductivity and dielectric constant: Determines whether calibration is needed and the probe material.
- Process temperature and pressure: Select the corresponding temperature and pressure resistance level.
- Corrosiveness: Choose materials such as PTFE, PFA, or Hastelloy.
- Output type: Choose relay, transistor, or NAMUR according to the control system interface.
- Certification requirements: Such as explosion-proof, sanitary certification, etc.
