Bestselling Original New Pressure Sensor With Display IFM PN2092 Best Controlling Perfect Performance

IFM PN2092 Electronic Pressure Sensor – 0…100 bar Precision for Industrial Liquids

The IFM PN2092 is an electronic pressure sensor with integrated digital display, designed for accurate measurement and control of liquid pressure in demanding industrial environments. With a measuring range from 0 to 100 bar and robust overload capability up to 300 bar, this sensor is well suited for hydraulic power units, coolant and lubrication systems, process skids, and general machine building where reliability and data transparency are critical. 

Built around a ceramic-capacitive measuring cell and a stainless-steel process connection, the IFM PN2092 combines long-term stability with high resistance to pressure spikes. Two configurable outputs, an analogue output and IO-Link communication make it more than a simple pressure switch – it becomes a compact data source for modern automation systems. 

Core Technical Data – IFM PN2092

Measuring Technology and Performance

At the heart of the IFM PN2092 is a ceramic-capacitive pressure cell, a technology chosen for its excellent long-term stability, low drift and resistance to corrosive liquids. Unlike metal diaphragms that can fatigue under repeated overload, the ceramic element offers strong resilience against pressure peaks, supported by a pressure rating of 300 bar and a burst pressure of around 650 bar. 

The 0…100 bar range makes the PN2092 a natural fit for:

• Hydraulic power packs and clamping circuits

• Lubrication and cooling systems on machine tools

• Pressure monitoring on industrial process skids

• Utility pressure lines in factories

With a typical accuracy better than ±0.4 % of span, the sensor provides precise feedback for both limit control and continuous monitoring, supporting energy optimisation and predictive maintenance strategies. 

Mechanical and Environmental Robustness

The G 1/4 internal thread process connection follows common industry standards, so the PN2092 can be screwed directly into manifolds, pump outlets, filter heads or pipe tees without exotic adapters. 

Key mechanical and environmental features include:

• Wetted parts in stainless steel for good corrosion resistance in typical industrial fluids

• Housing in reinforced PBT/PC plastics for impact and vibration resistance while remaining lightweight 

• Operating temperature from −25 to +80 °C, suitable for cold start conditions and warm oil applications 

• IP65/IP67 protection rating, allowing use in dusty, humid and splash-prone areas when installed with a proper M12 connector 

This combination means the PN2092 can be mounted directly on machinery, without needing separate protective housings in most standard environments.

Display, Operation and Local Diagnostics

On the front of the IFM PN2092 is a large, 4-digit red/green LED display. The colour can be configured for constant red or for alternating red/green indication, which allows you to highlight safe operating windows or alarm states visually. 

Additional LEDs show the selected pressure unit and the switching status of the outputs, giving technicians immediate feedback without connecting a laptop. Parameter setting is done through the front pushbuttons, using a structured menu:

• Selection of units (bar, psi, MPa)

• Configuration of switching points and reset points

• Choice of hysteresis or window function

• NO/NC behaviour for each switching output

• Selection and scaling of the analogue output (4–20 mA or 0–10 V)

• Damping and response times for filtering noisy signals

The upper housing section can be rotated by about 345°, so you can align the display and buttons after installation – extremely helpful in tight or awkward mounting positions. 

Outputs, IO-Link and System Integration

The PN2092 is particularly flexible on the electrical side. It provides:

• Two digital outputs (PNP or NPN), each programmable as normally open or normally closed, with current rating up to 250 mA and switching frequencies below 500 Hz. 

• One analogue output that can be configured as 4–20 mA current or 0–10 V voltage, with a scalable range (1:5) to focus on the most relevant pressure window for the process. 

• IO-Link communication, enabling direct digital access to the measured pressure, configuration parameters and diagnostic information from the PLC or IO-Link master. 

The electrical design supports both PNP and NPN wiring, powered from a standard 18…30 V DC supply. Built-in reverse polarity, short-circuit and overload protection, together with an integrated watchdog, help safeguard the device in case of wiring mistakes or external faults. 

This blend of classic switching behaviour, analogue transmission and digital IO-Link data means the PN2092 can slot into legacy PLC systems today and still be part of a fully networked, data-rich architecture tomorrow.

Typical Applications for IFM PN2092

Because of its 0…100 bar range and liquid-oriented design, the IFM PN2092 pressure sensor appears in many use cases:

• Hydraulic units: supervision of main pressure, accumulator charging control, and protection against overpressure.

• Cooling and lubrication systems: monitoring pressure of coolant circuits on CNC machines, spindle lubrication and gearbox oil lines.

• Process and utility skids: pressure feedback on pump skids, filtration units and heat-exchanger loops.

• General OEM machinery: standard pressure node in packaging, textile, printing and assembly lines using oils, emulsions or water-based fluids.

When IO-Link is used, each of these applications also benefits from easier parameter management, remote diagnostics and simplified sensor replacement workflows.

Selection and Installation Considerations

To get the best performance from the IFM PN2092:

• Match the 0…100 bar span to your process so that normal operating pressure sits roughly between 25 % and 75 % of the range – this maximises resolution for both analogue and IO-Link process values.

• Use suitable thread seals or sealing rings with the G 1/4 internal thread, and avoid excessive mechanical stress from rigid piping by using short flexible hoses where vibration is high.

• When integrating into a PLC, decide early whether one output will be analogue and the other digital, or if both should act as switching outputs, and map them accordingly.

• In IO-Link installations, standardise parameter sets so that commissioning and replacement become largely “plug-and-run” operations, reducing downtime during maintenance. 

Why Choose IFM PN2092 for Your System?

The IFM PN2092 pressure sensor with display delivers a combination of features that is attractive for both OEM designers and plant engineers:

• Stable ceramic-capacitive measuring technology with generous overload reserves

• Wide 0…100 bar measuring range tailored to liquid applications

• Clear, configurable red/green display and rotatable housing for fast on-site diagnostics

• Flexible I/O concept: dual digital outputs, analogue output and IO-Link in one compact device

• Robust mechanical construction and IP65/IP67 protection for real-world factory conditions

For plants moving from simple mechanical switches to smarter, data-driven pressure control, the IFM PN2092 offers a practical, future-ready upgrade that fits easily into existing process connections and control architectures while opening the door to modern IO-Link based diagnostics and optimisation.
