The IFM PN3571 pressure sensor is a durable and precise monitoring device developed for industrial applications requiring consistent and accurate relative pressure measurement. Designed with robust construction, wide media compatibility, and high electrical integrity, it provides long-lasting performance in demanding automation environments.

Engineered for versatility, the PN3571 is compatible with both liquids and gases, making it suitable for a wide range of industrial sectors. Whether deployed in hydraulic systems, pneumatic networks, water and cooling circuits, or process automation setups, this sensor delivers accurate, stable, and repeatable pressure data to support efficiency, safety, and equipment protection.

The sensor’s operational reliability is underlined by its ability to function effectively in environments with medium temperatures ranging from -25 to 80 °C. This wide range ensures dependable measurement performance in both chilled and moderately heated applications, making the PN3571 adaptable to diverse industrial conditions.

Electrically, the PN3571 is designed with safety and durability in mind. It operates on 18…30 V DC in line with SELV/PELV requirements, ensuring safe low-voltage operation that complies with international standards. This provides protection for operators, connected systems, and ensures suitability for integration into global industrial environments.

One of the standout features of the PN3571 is its minimum insulation resistance of 100 MΩ (at 500 V DC). This ensures strong electrical integrity, providing protection against leakage currents and guaranteeing reliable long-term operation in electrically demanding environments. This feature enhances system safety and helps maintain consistent sensor performance, even when exposed to high voltages during testing or operation.

The device also benefits from gold-plated contacts, which maintain signal integrity, resist oxidation, and extend the lifespan of electrical connections. This attention to detail ensures that the PN3571 performs reliably even in harsh industrial environments with electrical noise or corrosive influences.

In practice, the PN3571 supports operators by delivering precise and repeatable pressure readings, enabling process optimisation, equipment protection, and reduced downtime. Its rugged build and compact format make installation straightforward in both new setups and retrofit projects, while its stable performance reduces recalibration requirements and overall maintenance effort.

In summary, the IFM PN3571 pressure sensor combines accuracy, reliability, and electrical robustness in a compact industrial-grade solution. With its compatibility with liquids and gases, safe SELV/PELV-compliant operation, broad temperature tolerance, and high insulation resistance, it is a trusted choice for industries that demand stable and durable relative pressure monitoring under a variety of operating conditions.
