The Keyence AP-C33WP is a compact and reliable digital pressure sensor designed to deliver precise measurement of positive pressure in air and non-corrosive gases. With a rated pressure range from 0 to +1.000 MPa, the unit is suitable for a broad variety of industrial applications, including pneumatic system monitoring, leakage detection, and process control. Its gauge pressure measurement capability ensures accurate readings referenced to atmospheric pressure, allowing operators to easily monitor system conditions.

One of the strengths of this sensor is its clear, dual-color LED display system. The 3 ½-digit, 7-segment LED with an 11 mm character height provides bright, easy-to-read measurements, while dual red operation indicators correspond to the unit’s two control outputs. The display updates at a cycle of 10 times per second, offering real-time responsiveness. Additionally, operators can choose between normal mode resolution (0.001 MPa) for precision measurements or focus mode (0.1 kPa) for enhanced readability when monitoring trends or general performance.

The AP-C33WP excels in integration flexibility. It offers two PNP open-collector outputs (100 mA max. each, selectable NO/NC configuration), enabling use in alarm systems, automated control, and process monitoring. The sensor also provides a 1–5 V analog output for continuous feedback, with the option to switch this function to a zero-shift input, giving users greater control and adaptability in system design. The response time is selectable from 2.5 ms to 500 ms, ensuring stability and chatter prevention in both fast-response and steady-state monitoring applications.

Energy efficiency and durability are also integral to the AP-C33WP. In eco mode, the unit reduces consumption to just 30 mA at 24 V, while standard operation remains efficient at less than 40 mA. Its pressure resistance of 1.5 MPa guarantees safety against overpressure events, and its rugged housing, made from polysulfone, PBT, polycarbonate, and zinc die-cast materials, ensures long-lasting use in demanding industrial environments. The unit is also resistant to vibration (10–55 Hz, double amplitude 1.5 mm across three axes), further supporting reliability in dynamic machinery setups.

Weighing only 30 g without cable (85 g with 2 m cable), the AP-C33WP is lightweight and easy to install. It comes complete with a power supply cord and unit seal, making setup straightforward and maintenance minimal.

In conclusion, the Keyence AP-C33WP provides a powerful blend of high-accuracy pressure sensing, user-friendly display, flexible outputs, and robust construction. It is an ideal solution for industries seeking a compact yet highly reliable pressure sensor that ensures accurate monitoring and efficient operation in pneumatic and gas-handling systems.
