PRECISION SEMICONDUCTOR PRESSURE SENSOR
Description
PF (ADP1)
PRECISION SEMICONDUCTOR PRESSURE SENSOR
• 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 pressure characteristics.
• Impressive line-up of models • Taking their place alongside the standard 5kΩ bridge resistance models are those with a 3.
3kΩ resistance which is optimally suited to 5V drive circuits.
• Economy model (no glass base) gives outstanding value for consumer appliances 40 kPa (0.
4 kgf/cm2) and 49 kPa (0.
5 kgf/cm2) units are also available.
