Pressure Sensor | Ultra High Precision Digital Output Pressure Sensor DLLR Series
DLLR series
This is a low-pressure sensor designed and developed for engineers seeking digital output pressure sensors that require high precision.
The "DLLR series" offers excellent performance in pressure ranges of 10 and 30 inch H2O, featuring the best overall accuracy error and precision in its class. Designed for engineers seeking high-precision digital output pressure sensors, it includes an automatically selected I2C or SPI interface, providing outputs with a resolution of 16/17/18 bits and typical linearity and hysteresis of ±0.05% FSS (calculated from BFSL). Utilizing All Sensors' proprietary CoBeam2TM technology, it enhances sensitivity while reducing package stress and possesses orientation characteristics due to our unique robust and highly stable dual-die technology. With a low variable supply voltage of 1.68V to 3.6V and a standby power consumption of less than 1μW, the DLLR series is suitable for designs aimed at low power consumption. This product is ideal for battery-operated designs with excellent performance. The product is available for gauge pressure and differential pressure in pressure ranges of 10 and 30 inch H2O (2488 Pa and 7465 Pa).

Company information
All Devices Co., Ltd. (formerly All Sensors Asia Pacific Co., Ltd.) was established on July 1, 2015. Our sensors, utilizing unique sensing technology, achieve high precision and stability, particularly in low-pressure and micro-pressure applications. We have gained support from companies that require accurate measurement of small pressures in fields such as medical, industrial, and IoT. Requests from our customers have expanded beyond differential pressure, leading to numerous inquiries and orders. We are now able to assist not only with fluid measurements such as pressure, flow rate, and wind speed but also with various sensors for temperature, oxygen, and even consulting services. In light of this progression, we have changed our company name to All Devices Co., Ltd. to reflect our capability to respond to any inquiries. Although we have changed our name, we will continue to provide support as the official representative office of All Sensors in the Asia Pacific region, just as we have in the past. We are committed to enhancing our expertise and international perspective to meet the expectations of even more customers. All Devices Co., Ltd. President and CEO, Tetsuo Hata
