The Keyence AP-14SK Sensor Head is a high-performance positive pressure sensor designed for accurate and reliable monitoring of high-pressure systems. With a rated pressure range of 0 to 10 MPa (0 to 1450 PSI), it is optimized for use in demanding industrial applications where consistent measurement of gases and liquids is critical to maintaining operational safety and efficiency.

Engineered for gauge pressure measurement, the AP-14SK delivers precise readings with repeatability within 0.5% of full scale, ensuring stable and dependable performance even under fluctuating process conditions. This accuracy makes it ideal for applications such as hydraulic system monitoring, pneumatic control, pressurization processes, and testing environments where precise feedback is essential.

The unit’s pressure port uses a 1/4 NPT threaded connection with a built-in throttle, simplifying integration into existing pipelines and equipment. The inclusion of a throttle provides additional protection by reducing the effects of sudden pressure surges, extending the operational life of the sensor.

Durability is a key strength of the AP-14SK. Constructed from 304 stainless steel and TYPE S17400 stainless steel for the diaphragm and pressure port, the sensor offers excellent corrosion resistance, mechanical strength, and reliability when exposed to challenging process fluids. The robust materials ensure compatibility with a wide range of gases and liquids, including those typically used in heavy industry.

The AP-14SK is designed to withstand harsh operating conditions. It carries an IP67 enclosure rating, providing protection against dust and water ingress. With pressure resistance up to 2900 PSI (20 MPa), it delivers safe performance even when subjected to occasional overload conditions. The sensor operates reliably within a wide temperature range of -20 to +100 °C (-4 to 212 °F), making it suitable for high-temperature processes and variable environments.

Industrial environments often expose sensors to continuous vibration and shock, but the AP-14SK is built to endure these stresses. It withstands vibration from 10 to 55 Hz at 1.5 mm double amplitude for three hours in each axis, as well as shock resistance of 500 m/s² applied ten times in each direction (a total of 60 shocks). These specifications guarantee stable measurement even in heavy machinery, production lines, and environments with frequent mechanical impact.

Weighing just 130 g, the AP-14SK combines ruggedness with a compact, lightweight form factor that makes installation straightforward without compromising durability. Each unit is supplied with a sensor head connector, simplifying system integration.

In summary, the Keyence AP-14SK Sensor Head is a durable, precise, and high-capacity positive pressure sensor that combines stainless-steel strength, repeatable accuracy, and rugged environmental resistance. Its compact yet robust design makes it ideally suited for industries such as automotive, heavy machinery, fluid power systems, and process automation, where reliable high-pressure monitoring is essential.
