All Sensors DLC Series Compact High-Resolution Pressure Sensors

Product Overview

The DLC Series Compact High-Resolution Pressure Sensor from All Sensors utilizes CoBeam2 Technology to enhance long-term stability by reducing package stress susceptibility. This advancement in piezoresistive pressure sensor technology offers exceptional space savings and optimal performance for compact applications. With a low supply voltage and 16-bit digital resolution, these sensors integrate seamlessly into various process control and measurement systems, including direct connection to I2C serial communication channels. They are suitable for battery-powered systems with low-power modes and provide accurate, stable output over a wide temperature range. The DLC series is designed for use with non-corrosive, non-ionic working fluids such as air and dry gases.
