1 / 4 page 27 PRECISION SEMICONDUCTOR PRESSURE SENSOR PF PRESSURE SENSOR PF (ADP1) • A wide range of rated pressure, including a minute pressure There are 10 types of sensors covering a wide range of rated pressure from a minute pressure between 4.9 kPa {0.05 kgf/cm2}, to a maximum pressure of 980.7 kPa {10 kgf/cm2}. • Realization of highly accurate, linear characteristics This sensor employs a semiconductor strain gauge method, ensuring accurate and linear detection characteristics. It also has excellent repeatability of pres- sure characteristics. • Impressive line-up of models • Taking their place alongside the stan- dard 5k Ω bridge resistance models are those with a 3.3k Ω resistance which is optimally suited to 5V drive circuits. • Economy model (no glass base) gives outstanding value for consumer appli- ances 40 kPa (0.4 kgf/cm2) and 49 kPa (0.5 kgf/cm2) units are also available.
