The Keyence AP-34KP extends the AP-30 series into compound pressure measurement. Specifically, it covers a rated range of 29.9 to -29.9 inchHg, so one unit handles both vacuum and positive pressure tasks. Technicians often use it for suction verification, vacuum clamping, and leak testing.
Additionally, the sensor carries a 3½-digit, 2-color, 7-segment LED display with 11 mm character height. Operators can read values quickly across the workshop floor. Display resolution reaches 0.1 inchHg, 0.2 kPa, 2 mmHg, or 0.002 bar, depending on the selected unit.
Furthermore, the AP-34KP pressure sensor provides PNP open collector outputs with two selectable modes (N.O./N.C.). A 1 to 5 V analog output supports external monitoring devices. Response time is selectable among 2.5, 5, 100, and 500 ms to suppress chattering.
The rated pressure range spans 29.9 to -29.9 inchHg, 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 shifts color at set thresholds, which helps operators catch abnormal conditions at a glance.
The Keyence AP-34KP runs 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 delivers 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 control and analog 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 72.5 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-34KP on a flat surface using the designated mounting bracket. First, connect the pressure port to the vacuum or pressure 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, confirm the display readings against a reference gauge before regular operation.
