RoHS compliant

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.
