A wrong pressure in an installation can have devastating consequences for life and limb, or seriously damage the installation. The PN can avoid this: it features high overload resistance and is very easy to set. It has a green / red display, 3 buttons with clear symbols and can be rotated by 330° for optimum orientation in the installation. Also the visible corner LEDs ensure clear readability. The direct labeling with QR code leads directly to important product information.
