Features

  1. 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}.

  2. 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.

  3. 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.
