          *1 Note: You may not be able to connect the sensor head to the amplifier unit depending on when the amplifier unit was purchased.For details, contact your local sales office.
          *2 Value when the ambient temperature is 20 °C.
          *3 Representative value at the centre of the measuring range. Please note that the measuring force varies by the installation state of the dust boot. This is a representative value when using the GT2-PA12K/PA12 with a pressure of 0.25 MPa. The measuring force varies depending on the air pressure used. For details, see table 1.
          No dust boots are used with the GT2-PA12K/PA12.
