Amphenol All Sensors DLHR Low Voltage Digital Pressure Sensors
Amphenol All Sensors DLHR Low Voltage Digital Pressure Sensors feature a 0.5inH2O to 60inH2O pressure range and a 1.68V to 3.6V supply voltage range. Amphenol All Sensors DLHR series is based on CoBeam2™ technology that reduces package stress susceptibility for improved long-term stability and position sensitivity. The digital interface makes it easy for designers to integrate 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 (-25°C to +85°C). 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.
