Pascal-MF

Measurement instruments for the semicon industry

Manufacturer: Novasina
SKU: 1115961

Pascal mass flow differential pressure sensors

High end measurement instruments for monitoring and controlling of very low differential air pressure in clean rooms, flow boxes and mini-environments.

Advantages

  • Outstanding accuracy, reproducibility and stability
  • High measurement resolution -> ideal for low pressures
  • No drift or hysteresis -> optimal for control systems
  • Non-sensitive to overpressure -> high product safety
  • Maintenance free -> low operational costs

 

Differential pressure measurement instruments with mass flow sensor

 

These measurement devices detect differential pressure by converting the air flowing through the sensor. The flow direction is defined by the pressure conditions and goes from the higher pressure to the lower pressure area. This so called mass flow is measured with a thermic principle with a hot wire. The mass flow is then converted to a differential pressure value. This measurement does not require any mechanical sensor parts, which offers unique characteristics in terms of accuracy, robustness and stability.

 

Range of use

Pascal mass flow differential pressure sensors are suitable very low pressures < 10 Pa.

Thanks to their high resolution even pressures below 2 Pa can be controlled accurately

 

Applications

  • Mini-enviroments 
  • Clean rooms
  • Laminarflow boxes and fume hoods
  • Air locks
  • Leakage testing systems
