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.
