All Sensors DLC Series Compact High-Resolution Pressure Sensors
Product Overview
The All Sensors DLC Series is a line of compact, high-resolution pressure sensors built upon the advanced CoBeam2 Technology. This technology significantly enhances long-term stability by minimizing package stress susceptibility, setting a new standard for piezoresistive pressure sensors. Designed for space-constrained applications, these sensors offer optimal performance and exceptional space savings, with package sizes as small as 7mm x 7mm. Their low cost makes them ideal for high-volume applications requiring budget-friendly solutions. The low supply voltage (1.8V to 3.6V) facilitates seamless integration into various process control and measurement systems, including direct connection to I2C serial communication channels. Featuring 16-bit digital resolution, the DLC series provides accurate, calibrated, and compensated output over a wide temperature range. These sensors are intended for use with non-corrosive, non-ionic working fluids like air and dry gases. Low-power modes are available for battery-powered systems, minimizing power supply load between readings.
