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. The DLHR series is based on CoBeam2™ technology that reduces package stress susceptibility for improved long-term stability and position sensitivity. The digital interface provides easy integration into process control and measurement systems, allowing direct connection to serial communications channels. For battery-powered systems, the sensors can enter an ultra-low-power mode between readings to minimize the load on the power supply. These calibrated and compensated sensors provide accurate, stable output over a -25°C to +85°C temperature range. Amphenol DLHR Low Voltage Digital Pressure Sensors are intended for use with non-corrosive, non-ionic working fluids such as air, dry gases, and the like. An optional protective parylene coating offers protection from moisture and harsh environments.Features
