Overview
The Keyence AP-44 is a sensor head engineered for digital pressure measurement in industrial automation and process control. This compound pressure-type head measures gauge pressure in a range of +101.3 to -101.3 kPa (±14.5 psi) and is designed to pair with Keyence amplifier units. The modular head-and-amplifier design enables remote mounting in confined spaces while the main controller remains accessible.
