The Keyence AP-14SK sensor head is a positive-pressure type model specifically engineered for high-pressure monitoring in industrial systems. With a rated pressure capacity of up to 1450 PSI and a pressure resistance of 2900 PSI, this sensor head is well-suited for rigorous applications requiring precise and stable pressure measurement under extreme operating conditions.

One of the core strengths of the AP-14SK lies in its robust stainless steel construction. The diaphragm and pressure port are manufactured using S17400 and 304 stainless steel, materials chosen for their high resistance to corrosion, wear, and compatibility with a wide range of gases and liquids. This ensures that the sensor head not only delivers accuracy but also withstands long-term operation in challenging environments where exposure to aggressive media and high pressures is common.

Designed to perform reliably in tough conditions, the AP-14SK is IP67 rated, making it resistant to dust and water ingress. The unit maintains stable performance across a broad ambient temperature range of -20 to +100 °C, and it is rated for operation in humidity levels from 35% to 85% without condensation. Its mechanical durability is further proven through vibration resistance of up to 1.5 mm amplitude at 10–55 Hz and shock resistance up to 500 m/s², ensuring reliability even in environments where equipment is exposed to constant movement or impact.

From a measurement standpoint, the AP-14SK delivers excellent repeatability of 0.5% of full scale, enabling accurate and consistent readings in process control and monitoring. The gauge pressure type measurement system ensures real-time monitoring of pressure against atmospheric reference, making it suitable for applications ranging from hydraulic and pneumatic systems to industrial automation and process industries. The 1/4 NPT connection with throttle provides a secure and stable interface, enhancing measurement reliability and reducing risks of leakage or failure under high-pressure conditions.

At just 130 g, the AP-14SK maintains a compact and lightweight profile, allowing flexible installation in a variety of system layouts. Despite its small size, it is engineered for heavy-duty use, making it highly suitable for industries such as oil and gas, chemical processing, power generation, and general manufacturing.

In summary, the Keyence AP-14SK sensor head combines high-pressure tolerance, rugged stainless steel construction, precision repeatability, and superior environmental resistance in one compact unit. Its ability to deliver reliable measurements under extreme operating conditions makes it an indispensable component for industries seeking to enhance operational safety, efficiency, and performance in pressure-critical applications.
