Compact installation

Body width is 30㎜ and height is 30㎜.

Lock function is built-in

Wrong output by misoperation can be prevented by locking function.
Key icon is displayed in operating mode.

Excellent cost effectiveness.

Price down of -46.5% was achieved, compared to conventional large digital pressure sensor 30 series.
New large digital pressure sensor comes with reasonable price.

Power-save mode can reduce power consumption by 30%

During power-save mode, the main display will turn off if no button is pushed for 30 seconds.
