General Description
• Portable/Hand-Held Equipment
The MLV Series Compensated Sensor is based on All Sensors’ CoBeam
2 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 operat-
ing at higher voltages. This lower supply voltage gives rise to improved warm-up shift while the CoBeam
2
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.
