IFM PN2515 Pressure Sensor with Display – Reliable Vacuum and Pressure Monitoring for Industrial Systems

The IFM PN2515 is an electronic pressure sensor with an integrated digital display, designed for accurate measurement of relative pressure and vacuum in industrial automation systems. With a measuring range from -1…6 bar (-14.5…87 psi), robust housing and flexible output options, it is an excellent choice for applications such as pump control, pneumatic circuits, hydraulic monitoring and general machine condition monitoring. 

Key Technical Data (Summary Table)

Designed for Precise Pressure and Vacuum Control

The PN2515 is built to handle both vacuum and positive pressure in a single compact device. Its measuring range from -1 bar up to 6 bar enables it to cover typical pneumatic vacuum levels, slightly elevated pressure ranges and low-pressure hydraulic or water circuits. This makes it suitable for tasks such as:

• Supervising vacuum circuits in pick-and-place systems

• Monitoring low-pressure cooling or lubrication lines

• Controlling compressed air in packaging and handling equipment

• General pressure status indication in small hydraulic systems

The ceramic-capacitive measuring cell provides excellent long-term stability and resistance to overload. Combined with an overload rating of 40 bar and a bursting pressure of 100 bar, the sensor can withstand harsh operating conditions and occasional pressure spikes without losing its calibration. 

Flexible Output Concept for Modern Automation

One of the main strengths of the IFM PN2515 is its flexible output configuration. The device features two digital switching outputs and one analogue output, and the user can parameterise the outputs according to the control strategy: 

• Digital outputs can be configured as normally open or normally closed and can act as limit switches, alarms or control signals for contactors and valves.

• The analogue output can be set either as a 4…20 mA current signal or as a 0…10 V voltage signal, with a scalable measuring span (1:5), enabling precise integration with PLC analogue input modules or data acquisition systems.

• Electrical design supports both PNP and NPN switching, helping the sensor fit into existing wiring philosophies without major redesign.

In addition, the PN2515 supports IO-Link communication, allowing process values, diagnostic information and parameters to be exchanged with an IO-Link master. This opens the door to advanced diagnostics, simplified commissioning and quick recipe changes directly from the PLC or a higher-level control system. 

Robust Construction for Demanding Media

The PN2515 is designed for industrial environments where equipment must tolerate aggressive conditions. The sensor can be used with a wide variety of liquids and gases, including compressed air, inert gases, water and many common hydraulic or cooling media, as long as they are compatible with the wetted materials. The specified medium temperature range of -25…80 °C covers most factory applications, from chilled media to warm process lines.

Gold-plated electrical contacts enhance signal reliability in high-vibration or high-humidity environments. Internal protective functions such as reverse polarity protection, short-circuit protection and overload protection reduce the risk of damage from wiring mistakes or temporary fault conditions. 

Intuitive Red/Green Display and Rotatable Housing

The PN2515 includes a bright 4-digit alphanumeric display that can switch between red and green. Thresholds can be configured so that the display indicates “OK” or “out of range” status at a glance—for example, green when pressure is inside the acceptable band and red when vacuum is lost or pressure exceeds a defined limit. 

The upper housing section can be rotated, allowing the display and buttons to face the operator, even in cramped panels or complex pipe layouts. This is particularly useful for OEM machine builders who need a clean visual layout, and for maintenance teams who want to see real-time pressure values without twisting hoses or cables.

Programming is handled via integrated push buttons at the front of the unit. Common settings include:

• Switching points and reset points (SP/rP)

• Hysteresis or window function

• Switching delays to filter out pressure peaks

• Scaling and direction of the analogue output

• Display units (bar, psi, kPa)

The combination of visual feedback and simple parameterisation reduces commissioning time and makes adjustments during maintenance straightforward. 

Accuracy and Stability for Reliable Process Control

The PN2515 is not just a simple “pressure on/off” switch – it offers measurement performance suitable for demanding control tasks. Typical performance data include: 

• Switch point accuracy better than ±0.4 % of span

• Repeatability typically within ±0.1 % of span (for moderate temperature variation)

• Low temperature coefficients for both zero point and span

• Long-term stability in the range of ±0.05 % of span per six months

These characteristics help to ensure that the pressure reading remains trustworthy over time, which is important for energy-efficient compressor control, precise vacuum regulation and stable pump operation.

Typical Application Areas

Thanks to its pressure range, output flexibility and mechanical design, the IFM PN2515 is widely applicable across multiple industries, for example:

• Packaging and handling machinery – vacuum grippers, carton forming, sealing pressure supervision

• Food and beverage utilities – compressed air networks, CIP return lines (where medium compatibility allows)

• General factory automation – pneumatic circuits on assembly lines, actuator pressure feedback, filter monitoring

• Machine tools and metalworking – coolant pressure monitoring, lubrication systems, chip conveyor pressure control

• HVAC and building services – monitoring of pump pressure and vacuum in utility systems

In each of these environments, the combination of clear red/green indication, analogue feedback and digital switching gives both operators and controllers a complete picture of system pressure status.

Advantages in Machine Design and Maintenance

For OEM designers, specifying the IFM PN2515 pressure sensor can simplify the bill of materials: a single model covers both vacuum and positive pressure ranges, includes switching and analogue outputs, and integrates IO-Link for advanced diagnostics. That reduces the need for multiple sensor types for similar tasks.

For maintenance and operations teams, the unit offers:

• Quick status checks via the colour display

• Easy replacement without extensive re-wiring, due to common G 1/4 process connection and flexible output modes

• Parameter storage via IO-Link (when used) so that sensors can be replaced with minimal re-configuration effort

These characteristics translate into reduced downtime and more predictable operation over the lifetime of the equipment.

Conclusion

The IFM PN2515 pressure sensor with display is a compact yet powerful solution for monitoring and controlling vacuum and low-pressure ranges in industrial applications. Its wide measuring range, robust ceramic-capacitive measuring cell, flexible outputs (including analogue and IO-Link), and highly visible red/green display make it suitable for both new machine designs and retrofit projects.

For users seeking a reliable, long-term pressure and vacuum monitoring device that can integrate seamlessly with modern PLCs and diagnostic systems, the PN2515 is a strong candidate that balances performance, robustness and ease of use.
