Under extreme process conditions, many measuring techniques quickly reach their limits. Not so with ProTrac, the new development from VEGA: this radiation-based measuring instrument is completely unaffected by high vessel pressures, aggressive media, extreme temperatures or difficult physical characteristics of the product. Because, ProTrac measures contactlessly right through vessel walls with the help of gamma radiation.

With the development of ProTrac, VEGA has set new standards of reliability and safety in radiation-based measurement: with regard to the sensitivity of detectors and the quality of source holders.

All ProTrac sensors were developed in compliance with the strict specifications of IEC/EN 61508 and fulfil the highest requirements. VEGA is the first supplier of SIL-qualified measuring instruments for radiation-based level, limit level, density, interface and mass flow measurement. In addition, all ProTrac sensors have an ingenious asset management system at their disposal.

As part of the proven plics instrument concept, ProTrac makes commissioning and adjusting a radiation-based measurement as simple as never before. The indicating and adjustment module PLICSCOM can be used to set the parameters of simple level or density applications. High-performance DTMs and EDDs are available for complex measuring tasks with several detectors or additional sensors for temperature or flow rate measurement.

Another special feature of ProTrac: every ProTrac instrument can be equipped with the most suitable detector for the particular area of application – SoliTrac, for example, with its PVT rod detector up to 3 m long, is a specialist for cylindrical vessels. The flexible and up to 7 m long detector tube of FiberTrac, which flexibly adapts itself to the vessel form, lends itself well for round and conical vessels. The NaJ crystal detector of MiniTrac stands out due to its small dimensions that find room even in corners or thin pipes.
