Solitrac 31 Radiometric Level Sensor

Brand: VEGA
The Solitrac 31 is a radiation-based sensor with PVT rod detector for continuous measurement of liquids and bulk solids. 

It is suitable for level and interface measurement under extreme process conditions, in aggressive products or products with critical properties. 

The Solitrac 31 is ideal for use in cylindrical vessels, reactors, autoclaves, separators and mixing vessels.
Features
  • High plant availability through non-contact measurement
  • Best measurement performance through PVT detector with maximum sensitivity
  • Simple mounting through supplied accessory
