Digital Ultra-Low Pressure Sensors offer high offset stability.
Press Release Summary:
December 10, 2012 - With ranges from 25 Pa (0.1 in. H2O) FS, LDE flow-based differential pressure sensors use compensation technology to achieve offset stabilities of better than 0.1 %. Included MCU enables precision digital signal conditioning, while digital SPI bus and analog output are concurrently available. Based on sensitive thermal mass flow measuring principle sensors for air and gases, sensors integrate flow channel within silicon sensor chip, promoting immunity to dust contamination and humidity.

New Digital Ultra-Low Pressure Sensors from 25 Pa (0.1 inH2O) offer Very High Offset Stability and Accuracy
Press release date: December 1, 2012
The LDE sensors for air and gases are based on a very sensitive thermal mass flow measuring principle and provide high-resolution signals. The innovative Sensortechnics technology integrates the flow channel including the sensing elements within the silicon sensor chip. Due to this extreme miniaturization on chip level the gas flow through the LDE sensor is decreased by several magnitudes compared to conventional flow-based pressure sensors. The sensors are therefore highly immune against dust contamination and humidity and allow the use of long connecting tubes and input filters without losing their calibrated accuracy. Further, complex housing constructions are not required thus providing small and cost-effective devices for space saving PCB mounting.
The digital LDE sensors are ideally suited for highly accurate and long term stable ultra-low pressure measurement in many medical, HVAC and instrumentation OEM device applications.
Important features of the new LDE series:
- Ultra-low pressure ranges from 25 Pa (0.1 inH2O) full scale
- Very high offset stability and accuracy
- Digital SPI bus and analog output at the same time
- High immunity against dust contamination and humidity
