All Sensors DLLR High Accuracy Pressure Sensors
Amphenol All Sensors DLLR High Accuracy Pressure Sensors feature CoBeam2 technology that helps in reducing package stress susceptibility with improved position sensitivity and long-term stability. These pressure sensors come with a digital interface easing the integration of sensors into a wide range of process control and measurement systems. The sensors come with extra compensation terms programmed into each sensor, allowing system firmware to remove high-order linearity errors and providing extremely accurate pressure linearity. The DLLR pressure sensors are mini-digital output devices that can operate within the temperature range from -25°C to +85°C with a maximum supply voltage rating of 3.63Vdc. These high accuracy pressure sensors are ideal for applications such as medical breathing, environmental controls, HVAC, industrial controls, and portable or handheld equipment.

If you are in need of a sensor that will help take the pressure off your design work, then the Amphenol All Sensors DLLR Series could be the part for you. These pressure sensors are built around All Sensors’ CoBeam technology which reduces package stress susceptibility, resulting in improved long-term usage and stability (simply put, high-pressures are less likely to damage the package and sensing device). Each sensor is pre-programmed with compensation which reduces the number of high-order linear errors, while the use of a digital interface simplifies integration (thanks to the I2C bus, just two resistors, two wires, bam, you’re done). With pressure ranges from 10 to 30 inch H2O, a typical voltage supply range from 1.68 to 3.6 volts, and an accuracy of 0.10%, the DLLR Series are truly formidable pressure sensors, capable of being used in medical breathing, environmental controls, air conditioning, industrial controls, and portable equipment.
