Vega is the first supplier of SIL-qualified measuring instruments for radiation-based level and point level measurement. The ProTrac series was developed according to the strict specifications of IEC/EN 61508 and all sensors in this series fulfil the highest requirements. In addition, all ProTrac sensors have an ingenious asset management system.
Radiation-based technology
Under extreme process conditions many measuring techniques quickly reach their limits. This is where ProTrac is different as the radiation-based gauges remain completely unaffected by high vessel pressures, aggressive media, extreme medium temperatures or difficult physical product properties. Using gamma radiation, ProTrac sensors can measure contactlessly right through container walls – accurately and without maintenance.
A detector for each application
Another special feature of ProTrac radiation-based gauges is that every instrument can be equipped with a detector best suited for its respective area of application. For example, the SoliTrac is specialised for cylindrical vessels, with a PVT rod detector that can reach up to three metres.
The flexible FiberTrac, which has a detector tube with a maximum length of seven metres, is ideal for round and conical vessels; and the MiniTrac, with a NaI crystal detector, has a small, compact design.
A range of applications
Vega’s ProTrac series of gauges are suitable for a range of applications. An example is level measurement in a polyester melt process, where the gamma radiation penetrates the cylinder despite the rotation of the cylinder and the great heat generated during the process. ProTrac is also suitable for level detection in cellulose production and for density measurement of lime water in flue gas desulphurisation. They can also be used on conveyor belts to measure mass flow of a hot product such as clinker.
