Product Description

The Keyence AP-C30 is an ultra-compact digital pressure sensor designed to replace traditional mechanical gauges in industrial applications. It features a large 11-mm, two-color LED display that provides clear and easy-to-read pressure readings. The sensor offers a fast response time of 2.5 ms and a repeatability of ±0.2% of full scale, ensuring accurate and reliable measurements. With its built-in amplifier and selectable output options, the AP-C30 is suitable for integration into automated systems requiring precise pressure monitoring and control.​
