Product Overview: ifm electronic PN7094
The ifm electronic PN7094 is a high-precision electronic pressure sensor designed for the monitoring of system pressure in industrial machinery. Part of the versatile PN7 series, this sensor features a high-visibility two-color alphanumeric display and an integrated IO-Link interface. It is primarily used in pneumatic and hydraulic applications where reliable pressure control and digital communication are essential for process optimization and Industry 4.0 integration.
Technical Specifications and Digital Integration
The PN7094 offers a measuring range of -1 to 10 bar (-14.5 to 145 psi). It is equipped with two switching outputs that can be programmed as Normally Open or Normally Closed. The integration of IO-Link allows for remote parameterization and provides detailed diagnostic data, such as pressure peaks and internal temperature, which are vital for predictive maintenance strategies. Its ceramic-capacitive measuring cell is highly resistant to overpressure and ensures long-term stability even in demanding environments.
