The IFM PNI021 is a pressure sensor designed for applications requiring pressure measurement together with an analogue input for differential-pressure evaluation. It provides a 0 to 250 bar measuring range and is suitable for industrial liquids and gases. The sensor features two digital outputs and can process an external analogue pressure signal. Its integrated display and programmable switching functions support convenient local monitoring. The PNI021 is particularly useful for filter monitoring and differential-pressure applications when combined with suitable pressure transmitters.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The PNI021 covers a 0 to 250 bar measuring range for industrial pressure applications. It can be used as part of a differential-pressure monitoring arrangement with an additional pressure transmitter. The sensor provides programmable switching thresholds for evaluating pressure conditions. The analogue input accepts standard pressure-transmitter signals for system comparison. This makes it useful for monitoring pressure differences across filters and machine components.
The PNI021 includes an analogue voltage/current input for receiving a pressure signal from an external transmitter. The input supports 0 to 10 V and 0/4 to 20 mA signal formats. Two digital outputs provide pressure-dependent switching functions. The switching points can be programmed according to application requirements. This combination allows the sensor to perform pressure evaluation and machine-control functions.
The PNI021 uses a G 1/4 female process connection for connection to the pressure circuit. It uses an M12 connector for electrical integration. Gold-plated contacts are provided for industrial applications. The device operates from a DC supply and is designed for liquids and gases. Its construction supports integration into industrial pressure-monitoring systems.
The PNI021 is suitable for differential-pressure measurement and filter monitoring. It can be used in machine tools, hydraulic systems and industrial process equipment. A second pressure transmitter can provide the comparison signal for differential-pressure evaluation. The switching outputs can be used for filter-clogging alarms and maintenance signals. It is suitable for automated pressure monitoring in industrial systems.
