The Scienta Ash content sensor is a double sided measurement using gamma rays (either as a natural source or from an X-Ray tube) detected by a scintillation detector. The senor electronics is highly integrated and features a standard, built-in Profibus DP or Modbus interface. All calculations and compensations are performed in this single, high performance 32-bit processor. The receiver electronics include sorting of different energy levels enabling a stable detection of coatings.

The X-Ray transmitter version uses a custom 10 kV power supply, which enables operation without extra cooling. The whole sensor is very compact and fits into the standard scanner sensor carriage. Great attention has been given to the mechanical mounting of the receiver tube. It has a floating 4-way attachment, which insulates it against mechanical shock. As the receiver electronics is mounted on a single board, the reliability of the sensor is very high.
