Example of pressure characteristics
• A wide range of rated pressure,
including a minute pressure
(when the rated pressure is between 98.1 kPa
{1.0 kgf/cm2}
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}.
Drive current: 1.5 mA rated current; ambient temperature: 25°C 77°F

• Realization of highly accurate, linear
characteristics
<Cross-section of Sensor Chip>
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
• Medical equipment: Electronic hemody-
namometer
•
Taking their place alongside the stan-
dard 5kΩ bridge resistance models are
those with a 3.3kΩ resistance which is
optimally suited to 5V drive circuits.
• Home appliance: Vacuum cleaner
• Gas equipment: Microprocessor gas
meter, gas leakage detector
• Industrial equipment: Absorption
device, etc.
