LDE/LME Series – superior immunity to dust
In this application note LDE/LME differential pressure (∆p) sensors from First Sensor are experimentally compared to other sensors which use the same (thermal-anemometer-based, non-membrane) sensing principle, where differential pressure is inferred from a gas flow through the sensor. With dust in the air flow, all other sensors having flow impedance 15 Pa/(ml/s) to 300 Pa/(ml/s) went out of calibration or failed entirely while the LDE/LME sensors having flow impedance >10 kPa/(ml/s) kept their calibrated sensitivity. The LDE/LME ∆p sensors from First Sensor require only very tiny flows through their body and therefore provide high immunity to dust-bearing air.
The LDE/LME series low-pressure sensors with ranges from 25 Pa (0.1 inH2O) full scale sense differential air or gas pressure, inferring differential pressure from nanoliters per second gas flow through an integrated air flow channel having high flow impedance.
The transducer is a MEMS-based thermoanemometer on a monolithic silicon chip, only 4 mm2 (0.006 in2) in size. Further, the LDE/LME sensors utilize a microcontroller for precision digital signal conditioning.
