DLHR Series Low Voltage Digital Pressure Sensors
Features
• 0.5 to 60 inH2O Pressure Ranges
• 1.68V to 3.6V Supply Voltage Range
• I2C or SPI Interface (Automatically Selected)
• Better than 0.25% Accuracy
• High Resolution 16/17/18 bit Output
Applications
General Description
• Medical Breathing
• Environmental Controls
• HVAC
• Industrial Controls
• Portable/Hand-Held Equipment
The DLHR 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 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.
