MLV Series Low Voltage Pressure Sensors Features 1 to 30 inH2O & 5 to 150 PSI Pressure Ranges 5V Operation High Output Low Power Consumption Excellent Position Sensitivity Low Warm-Up Shift Enhanced Front to Back Linearity Protective Parylene Coating Option Applications Medical Breathing Environmental Controls HVAC Industrial Controls Portable/Hand-Held Equipment General Description 2 TM The MLV Series Compensated Sensor is based on All Sensors CoBeam Technology. The device provides a high output signal at a low operating voltage while maintaining comparable output levels to traditional equivalent compensated millivolt sensors operat- 2 ing at higher voltages. This lower supply voltage gives rise to improved warm-up shift while the CoBeam Technology itself reduces package stress susceptibility resulting in improved overall long term stability. The technology also vastly improves position sensitivity compared to conventional single die devices. These calibrated and compensated sensors give an acurate and stable output over a wide temperature range. This series is intended for use with non-corrosive, non-ionic working fluids such as air, dry gases and the like. A protective parylene coating is optionally available for moisture/harsh media protection. The output is also ratiometric to the supply voltage and designed to operate at 5.0 volts DC.
