MLV Series Pressure Sensors

The MLV Series Compensated Sensor is based on All Sensors’ CoBeam2 TM Technology. The device provides a high output signal at a low operating voltage while maintaining comparable output levels to traditional equivalent compensated millivolt sensors operating at higher voltages. This lower supply voltage gives rise to improved warm-up shift while the CoBeam2 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 fl uids 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 suply voltage and designed to operate at 5.0 volts DC.
