Basic Information
High precision pressure sensor (without amp.)
Features
-
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 4.9kPa {0.05kgf/cm2}, to a maximum pressure of 980.7kPa {10kgf/cm2}.
-
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 5kohm bridge resistance models are those with a 3.3kohm resistance which is optimally suited to 5V drive circuits.
- Economy model (no glass base) gives outstanding value for consumer appliances 40kPa (0.4kgf/cm2) and 49kPa (0.5kgf/cm2) units are also available.
Example of pressure characteristics (ADP1141)
