General Description
The DLVR Series Mini Digital Output Sensor is based on All Sensors’CoBeam2 TM Technology. This reduces package stress
susceptibility, resulting in improved overall long term stability. The technology also vastly improves position sensitivity
compared to single die devices.
The supply voltage options ease integration of the sensors into a wide range of process control and measurement sys-
tems, allowing direct connection to serial communications channels. For battery-powered systems, the sensors can enter
very low-power modes between readings to minimize load on the power supply.
These calibrated and compensated sensors provide accurate, 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.
