Overview
The Keyence AP-43 is a precision pressure sensor head engineered for industrial measurement and process control. As a positive-pressure type sensor, it measures pressures from 0 to 1.0 MPa (0–145 PSI) with high accuracy. The AP-43 integrates with Keyence’s AP-C40, AP-V40, and AP-40 series amplifiers and controllers, making it a flexible solution for applications requiring separate amplifier architecture.
Key Features
