The IFM PN7809 is a compact pressure sensor with an integrated display for monitoring pressure, vacuum and differential pressure in pneumatic systems. It provides a measuring range of -1 to 1 bar, making it suitable for low-pressure and vacuum applications. The sensor features two programmable digital switching outputs for pressure-dependent machine control. Its four-digit display provides convenient local visualization of the measured value and operating condition. The compact industrial design supports reliable installation in machines and compressed-air systems.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The PN7809 is designed for accurate measurement across a -1 to 1 bar pressure range. It can monitor relative pressure as well as vacuum and differential pressure conditions. The sensor provides switch-point accuracy better than ±0.5% of span and repeatability better than ±0.1% under specified temperature conditions. Configurable set and reset points allow pressure limits to be adapted to the application. Its measurement capability makes it suitable for pneumatic pressure monitoring and control.
The integrated four-digit alphanumeric display provides direct visualization of the measured pressure. Two digital outputs can be configured as normally open or normally closed switching functions. The outputs can also be configured according to the required machine-control strategy. Switching points and reset points can be programmed for individual applications. The display and switching indicators simplify commissioning, operation and maintenance.
The PN7809 is designed for industrial pneumatic applications and compressed-air networks. Its G 1/8 internal process connection provides convenient installation into compatible pressure circuits. The M12 electrical connection supports secure industrial wiring. The sensor operates from an 18 to 36 V DC supply and includes reverse-polarity and overvoltage protection. Its industrial construction and IP67 protection support reliable machine installation.
The PN7809 is suitable for compressed-air pressure monitoring in industrial machines. It can be used for vacuum monitoring, pneumatic control and differential-pressure applications. The programmable switching outputs can control valves, alarms and machine functions. Its display allows operators to verify pressure directly at the measurement location. It is particularly useful where compact pressure monitoring and switching are required.
