The Keyence AP-33KP belongs to the AP-30 series of digital pressure sensors. This model suits positive pressure measurement with a rated range of 0 to 145.0 PSI. Engineers often choose it for pneumatic systems, leak detection, and general gas monitoring tasks.
Additionally, the sensor offers a 3½-digit, 2-color, 7-segment LED display with 11 mm character height. Operators can read pressure values quickly on the factory floor. The display resolution reaches 0.2 PSI, 0.001 MPa, 0.01 kgf/cm², or 0.01 bar.
Furthermore, the AP-33KP pressure sensor provides PNP open collector outputs with two selectable modes (N.O./N.C.). A built-in analog output of 1 to 5 V supports external monitoring devices. The response time is selectable among 2.5, 5, 100, and 500 ms to reduce chattering effects.
The rated pressure range covers 0 to 145.0 PSI, while the detectable range extends from -15% to +110% of full scale. First, the sensor measures gauge pressure for air or non-corrosive gases. Second, the display temperature characteristic stays within ±1% of F.S. at 25 °C across the 0 to 50 °C range. Third, the 2-color LED switches color based on set thresholds, which helps operators spot abnormal conditions at a glance.
The Keyence AP-33KP operates on 12 to 24 VDC ±10% supply voltage. Current consumption reaches 50 mA maximum at 24 V and 90 mA maximum at 12 V. Moreover, the control output rating is 100 mA maximum at 30 V maximum, with residual voltage of 1 V maximum. The analog output provides 1 to 5 V with a load impedance of 47 kΩ minimum. However, this model includes no built-in communication ports or protocols. Therefore, signal integration relies on the analog and control outputs.
The front housing uses polyamide, and the front panel sheet uses PET. Meanwhile, the rear housing is made of polysulfone, and the pressure port uses die-cast zinc. The cable is an oil-proof cabtyre cable. The unit weighs approximately 120 g.
Operating temperature ranges from 0 to +50 °C without freezing. Relative humidity stays between 35 and 85% RH without condensation. Besides, proof pressure reaches 217.5 PSI. Vibration resistance covers 10 to 55 Hz with 1.5 mm double amplitude for 2 hours in each X, Y, and Z direction. Finally, no official protection rating is available for this model.
Mount the AP-33KP on a flat surface using the designated mounting bracket. First, connect the pressure port to the air or gas line with suitable fittings. Next, wire the 12 to 24 VDC power supply according to the terminal diagram. Then, connect the PNP output to the load and the analog output to the monitoring device. After that, set the response time and output mode through the front panel controls. Finally, verify the display readings against a reference gauge before regular operation.
