VEGASOURCE 85 Chinese Manual Download and Product Overview
VEGASOURCE 85 is a radioactive source device used in industrial nuclear radiation measurement systems, typically used in conjunction with radiation-based level and density measurement instruments such as VEGAPULS, VEGAFLEX, or MINITRAC. This product adopts a sealed source design and is suitable for non-contact measurement under harsh working conditions such as high temperature, high pressure, and strong corrosion.
This article provides the download entry for the VEGASOURCE 85 Chinese manual and systematically organizes its working principle, technical parameters, installation points, and safety specifications, making it convenient for engineering technicians and procurement personnel to quickly grasp key information.
Working Principle and Typical Applications
Working Principle
VEGASOURCE 85 contains a built-in radioactive isotope (such as Cs-137 or Co-60). The emitted gamma rays pass through the container wall and the measured medium, and are then received by the detector on the opposite side. The degree of radiation absorption by the medium is related to density and level, and the instrument calculates the measurement value accordingly.
- Non-contact measurement: Neither the source nor the detector contacts the medium, making it suitable for high-viscosity, strongly corrosive, high-temperature, and high-pressure conditions.
- Strong penetration ability: It can penetrate thick-walled metal containers, making it suitable for reactors, blast furnaces, pipelines, and other scenarios.
- High stability: It is not affected by changes in medium temperature, pressure, viscosity, color, etc.
Typical Applications
- Petrochemical industry: Level and interface measurement of reactors, separators, and storage tanks.
- Metallurgical industry: Liquid level detection in blast furnaces, converters, and continuous casting molds.
- Power industry: Material level monitoring in coal bunkers, ash hoppers, and desulfurization towers.
- Chemical industry: Density and level measurement of polymerization kettles, evaporators, and crystallizers.
Technical Parameters and Model Selection
During model selection, the source activity and shielding type must be determined according to the measurement range, container wall thickness, medium density, and safety requirements. The table below lists the typical parameter ranges of VEGASOURCE 85. Specific values are subject to the Chinese manual.

|---|---|
| Radioactive source type | Cs-137, Co-60, etc. |
| Source activity | Customized according to working conditions, commonly 1 mCi ~ several Ci |
| Shielding material | Lead, tungsten, depleted uranium, etc. |
| Operating temperature | -40°C ~ +200°C (depending on configuration) |
| Protection class | IP65/IP66 (higher optional) |
| Installation method | Flange, bracket, collimator installation |
Installation and Commissioning Points
Installation Steps
- Confirm on-site radiation safety permits, delineate control areas, and wear personal dosimeters.
- Position the source container and detector according to the design drawings to ensure the radiation beam is aligned with the detector window.
- Use a collimator to limit the radiation beam angle and reduce scattered radiation.
- Secure the source container to ensure the flange or bracket connection is firm and avoid loosening due to vibration.
- After installation is completed, use a radiation monitor to detect the surrounding dose rate and confirm compliance with limits.
Commissioning Precautions
- Before commissioning, a certified radiation safety officer must confirm that the source is in the closed state.
- During calibration, use standard media or known density/level conditions, and record background counts and full-scale counts.
- Regularly check the flexibility of the source switch to prevent jamming that could make it impossible to close.
- All operations should follow the VEGASOURCE 85 Chinese manual and local radiation safety regulations.
Safety Specifications and Maintenance
Radioactive source safety is the primary issue in the use of VEGASOURCE 85. The equipment must be operated by trained and authorized personnel, and a complete usage ledger and regular inspection system must be established.
- Conduct regular leak tests to ensure the source capsule is intact.
- Perform radiation dose rate detection at least once every 12 months.
- The source container should be locked, and the key should be kept by a designated person.
- Disused sources must be handed over to qualified units for recycling; private disposal is strictly prohibited.
During maintenance, please refer to the maintenance cycle table in the Chinese manual. When replacing seals or collimators, a new safety assessment is required.
Frequently Asked Questions (FAQ)
Where can the VEGASOURCE 85 manual be downloaded?
The PDF download link is provided at the top of this article. You can also contact the official VEGA distributor to obtain the latest version.
Does the radioactive source need to be replaced regularly?
The half-life of the radioactive source determines the rate of activity decay. When the activity falls below the minimum value required for measurement, a new source must be replaced. For the specific cycle, please refer to the Chinese manual and manufacturer recommendations.
What should I do if the measurement is inaccurate after installation?
First, check whether the source switch is fully open and whether the collimator is aligned with the detector; second, recalibrate the background and full scale; if it is still abnormal, contact the manufacturer's technical support.
