Advanced probe and quality assurance checks.

The DT990 includes the most advanced automatic functionality checks available on any probe system to provide full regulatory compatibility. The unique contamination circuit monitors for any leakage currents or signals across the insulator, hence providing the ultimate proof that the sensors measurement integrity is uncompromised. The automatic zero and span checks then provide proof that the electronic ampli. cation and conditioning of the signal is performed within pre-de. ned tolerances. The above features form part of World-Wide Patents.

Applications

Particularly suitable for bag . lter, cartridge . lter, dust collector and cyclone applications.

Enhanced measurement accuracy

Advanced signal processing techniques are used within the sensor electronics to provide the following measurement features:

 Rapid Dynamic Ranging of 10,000: 1 (Dynatrack) permitting bag cleaning pulses to be accurately monitored while maintaining

high accuracy in background emission measurement

 Rolling digital average calculations for accurate emission reporting
