basic information
The BLC series basic sensors are based on a dual-differential reference method to reduce output offset and common mode errors. Unlike previous equivalent class corrected millivolt sensors that could only be driven at higher voltages, they are designed to operate at lower drive voltages based on All Sensors' CoBeam2 technology. This low power supply allows for the packaging of silicon chips configured with CoBeam2TM technology, alleviating stress impacts, which in turn improves long-term stability and provides a stable warm-up shift. This technology dramatically improves the attitude characteristics compared to traditional single die sensors. This series is intended for use with non-corrosive, inert gases such as air and dry gases. The output is proportional to the power supply. It is designed to operate at 1.8 to 3.3 volts DC.

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
