Sensors and Micro Flow Sensors
Bridging the gap between sensing a physical phenomenon and representing it predictably as an electrical signal
should not be left to chance. Only Microbridge uses industry accepted Rejustor™ technology to ensure the most accurate
and reliable conversion. Starting with proprietary design techniques that pre-define flow impedance at the die level,
our sensors dramatically reduce demands on subsequent packaging, and individual units require only simple offset
and gain compensation. Applications include: HVAC, Medical CPAP, Blood pressure monitors and more.
MB-LPS1-01 Series Linear Analog-Conditioned Low Differential Air Pressure Sensors
The MB-LPS1-01 series low-pressure sensors sense differential air (or other non-corrosive gas) pressure, inferring differential pressure from nano-liters per second gas-flow through an integrated air-flow channel having high flow-impedance. The transducer is a MEMS-based thermo-anemometer on a monolithic silicon chip. Rejustor technology combined with CMOS circuitry provides on-chip-integrated analog-only compensation and conditioning electronics.
Differential Pressure Sensor Demonstration
FEATURES, BENEFITS- Linear Output
- High flow-impedance in the range of tens to hundreds of kPa/(ml/s)
- Dominates flow-impedance in series (in-line) configurations.
- Minimizes flow-through in parallel configurations.
- Allows use of filters and connection hoses without losing calibration.
- Rejustor-based analog-only on-chip signal conditioning electronics to compensate (Offset, TC-Offset, Span, TC-Span).
