Product Description
DLHR Series Low Voltage Digital Pressure Sensors
Product Overview
The All Sensors DLHR Series Mini Digital Output Sensor leverages CoBeam2 Technology to minimize package stress, enhancing long-term stability and reducing position sensitivity. Its digital interface simplifies integration into process control and measurement systems, allowing direct connection to serial communication channels. Designed for battery-powered applications, these sensors feature a very low-power mode to conserve energy between readings. Calibrated and compensated, they deliver accurate and stable output across a wide temperature range. The DLHR series is suitable for use with non-corrosive, non-ionic working fluids such as air and dry gases. An optional parylene coating is available for enhanced moisture and harsh media protection.
