• Portable/Hand-Held Equipment
The DLHR Series Mini Digital Output Sensor is based on All Sensors’ CoBeam^{2 TM} Technology. This reduces package stress
susceptibility, resulting in improved overall long term stability and vastly improves the position sensitivity.
The digital interface eases integration of the sensors into a wide range of process control and measurement systems,
allowing direct connection to serial communications channels. For battery-powered systems, the sensors can enter very
low-power mode 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.
