Description

The 21D series of pressure transducers, using chip-in-oil technology, is one of the most stable series among pressure sensors with a digital I²C (Inter-Integrated Circuit) signal. Using this digital signal, it is possible to obtain data on both pressure and temperature. Low power consumption (up to 3.6 volts) and automatic transition to "sleep" mode without power consumption allow these sensors to be used for autonomous solutions requiring long operating times, high stability, and excellent accuracy (0.15% FSO). The ability to connect sensors into a BUS system will allow full automation even of large facilities. Special attention should be given to the innovative and unique digital signal processing (DSP) technology used for compensation and normalization of output values!
