DLHR Series Low Voltage Digital Pressure Sensors
Product Overview
The All Sensors DLHR Series Mini Digital Output Sensor leverages CoBeam2TM Technology to offer enhanced long-term stability and reduced susceptibility to package stress and position sensitivity. Featuring a digital interface for seamless integration into process control and measurement systems, these sensors can connect directly to serial communication channels. Designed for battery-powered applications, they offer a very low-power mode between readings to minimize power consumption. These calibrated and compensated sensors deliver accurate, stable output across a wide temperature range and are intended for use with non-corrosive, non-ionic working fluids like air and dry gases. An optional parylene coating is available for added protection against moisture and harsh media. The DLHR series is ideal for applications including Medical Breathing, Environmental Controls, HVAC, Industrial Controls, and Portable/Hand-Held Equipment.
