Product catalog summary

Introduction to Radiation-based Measurement
Radiation-based measurement utilizes focused gamma rays emitted by a minimally radioactive isotope. A sensor positioned opposite the container receives the radiation, which is attenuated when passing through matter. This allows the sensor to calculate level, limit level, density, or mass flow based on the intensity of the received radiation. Key advantages include high operational reliability under tough conditions, independence from pressure, temperature, and product toxicity, and the ability to install the system externally during ongoing production.

Product Specifications

FIBERTRAC 31, FIBERTRAC 32, SOLITRAC 31: These are used for level and interface measurement of liquids and bulk solids with a measuring range up to 7 m for FIBERTRAC models and 3 m for SOLITRAC. They feature flexible plastic or PVT rod detectors and offer signal outputs like 4-20 mA/HART, Profibus PA, and Foundation Fieldbus. Approvals include ATEX, UKEX, IECEx, and others.
POINTRAC 31, MINITRAC 31, WEIGHTRAC 31: These models are designed for level detection, density measurement, and mass flow determination, respectively. They offer non-contact measurement with high reliability and are suitable for installation in confined spaces.
VEGASOURCE 31, 35, SHLD1, 81, 82, 83: These are source containers for radioactive isotopes with varying aperture angles and activity levels. They provide reliable shielding, allowing use without control areas, and are designed for minimal space requirements.

Key Benefits

Simple installation and cost savings due to flexible detectors and reduced source size.
Maximum accuracy and reliability through advanced detector technology.
Non-contact measurement ensures wear-free operation.
Compact design allows for easy retrofitting and installation in limited spaces.

Non-contact measurement with radiation-based measuring principle Radiation-based measurement is based on focussed gamma rays, i.e. radiation, emitted by a minimally radioactive isotope. The sensor, which is mounted on the opposite side of the container, receives this radiation. Because gamma rays are attenuated when penetrating matter, the highly sensitive sensor can calculate the level, limit level, density or mass flow from the intensity of the incoming radiation recieved.  Maximum operational reliability even under the toughest operating conditions  Measurement independent of pressure, temperature and product toxicity or corrosiveness  Measuring system can be installed externally and set up during ongoing production
