The Keyence AP-48 Differential Pressure Sensor Head is a robust and versatile device designed to provide precise pressure monitoring in a wide variety of industrial applications. Operating across a compound pressure range of -101.3 to +101.3 kPa, the AP-48 can handle both negative and positive pressure, making it highly adaptable to systems that require vacuum monitoring, low-pressure air handling, or differential gas measurements.

Constructed with durability in mind, the AP-48 combines a PBT (polybutylene terephthalate) case with SUS303 stainless steel screws and R1/8 pressure ports, providing not only structural integrity but also strong resistance against corrosion and wear. The sensor’s integrated PVC cable ensures a secure connection while maintaining flexibility and insulation, even in environments where long-term durability is critical.

Environmental resilience is another strength of the AP-48. It can withstand pressure up to 500 kPa, making it ideal for systems where occasional overpressure conditions might occur. Additionally, the sensor demonstrates strong resistance to vibration (10 to 55 Hz, double amplitude 1.5 mm) and shock (1,000 m/s² applied 60 times), ensuring consistent performance even in high-motion environments such as automated equipment or production machinery. This resilience guarantees that the sensor remains reliable in harsh conditions that often challenge precision instrumentation.

Accuracy is a key performance factor in pressure measurement, and the AP-48 delivers stable readings with temperature compensation of ±2% F.S. when exposed to environmental fluctuations. This ensures reliable results in facilities where ambient conditions vary, reducing the likelihood of process errors due to inaccurate pressure detection.

Practical and lightweight at approximately 98 grams including its cable, the AP-48 is simple to integrate into new or existing setups. Its compact size allows for installation in space-constrained applications, while its standard R1/8 pressure connection ensures compatibility with a wide range of pneumatic and gas control systems.

Designed primarily for air and non-corrosive gases, the AP-48 is well-suited for use in HVAC systems, pneumatic controls, semiconductor processing, leak testing, and other industrial automation processes where maintaining accurate pressure balance is crucial. Its versatility, combined with rugged construction and precision, makes it a trusted choice for engineers looking for reliable differential pressure monitoring in demanding environments.

In summary, the Keyence AP-48 is a well-balanced sensor head that delivers accuracy, durability, and adaptability, making it a dependable solution for modern industrial applications that require stable differential pressure measurement.
