Keyence AP-33P Pressure Sensor

The Keyence AP-33P is a main-unit pressure sensor from the AP-30 series designed for positive-pressure, gauge-pressure measurements up to 0–10 bar (0–1.000 MPa) with a PNP configuration. It accepts air or non-corrosive gases and features a built-in two-color LED display that presents a 3 1/2-digit readout (11 mm character height) for clear on-site monitoring. This compact unit is intended for direct installation in pneumatic lines and automation equipment, delivering reliable pressure visibility and straightforward integration within Keyence’s automation ecosystem, with documentation noting UL recognition (c/us) and CE markings. The AP-33P is specifically identified as the 1 MPaPositive-pressure variant within the AP-30 family.
