IFM Yifu Gate Pressure Sensor PN7271 Dual Open/Close Output

ifmPN7271It is a high-performance and intelligent deviceElectronic pressure sensorIt belongs to the IFM flagship PN7xxx series. It is based on the same software and hardware platform as PN7270, with the core difference beingThe pressure measurement range has been increased to 0... 100 barMake it an ideal choice for general hydraulic systems and high-pressure industrial applications.

Core attributes and range

Measurement principle: Ceramic capacitor type (high overload capacity, impact resistance).

Measurement type: relative pressure.

Pressure range: 0... 100 bar (0... 1450 psi, 0... 10 MPa).

This is the most widely used standard range in the fields of industrial hydraulics, high-pressure pneumatics, and water treatment.

Overload pressure (withstand pressure): 150 bar.

Burst pressure: ≥ 350 bar.

Applicable media: hydraulic oil, compressed air, water, coolant, non corrosive industrial liquids and gases.

Medium temperature: -25... 80 ° C.

Environmental temperature: -25... 80 ° C.

Storage temperature: -40... 100 ° C.

Structure and mechanical characteristics

Shell material: All stainless steel 316L, integrated seamless design, resistant to vibration, electromagnetic interference, and corrosion.

Connection thread: G 1/4 external thread (compliant with DIN EN 837 standard), integrated sealing ring installation groove, ensuring zero leakage under high pressure conditions.

Display screen: dual color 4-digit LED display screen (red/green).

Intelligent color change: The display color can be automatically switched according to the pressure state (for example, green is displayed within the normal range, red is displayed when reaching the switch point or exceeding the limit), which is convenient for quick on-site inspection.

The display can rotate 180 ° and adapt to any installation direction.

Protection level: IP 67 and IP 69K.

IP 69K means that the sensor can withstand high temperature and high pressure steam jet cleaning, suitable for sanitary environments such as food, beverage, pharmaceutical, etc. that require frequent flushing.

Electrical output and flexible configuration

PN7271 has a fully programmable output stage and extremely flexible output channel configuration:

1. Output channel:

OUT1: Programmable as switch output or analog output.

OUT2: Programmable as switch output or analog output.

Core advantage: Supports dual-mode analog output. One sensor can output two independent analog signals at the same time (for example: 4... 20 mA to PLC, 0... 10 V to field instrument), or both are switching values, or one is open and one is analog.

2. Switching parameter:

Load current: ≤ 250 mA.

Response time: ≤ 1.5 ms (millisecond level response, suitable for high-speed switching control systems).

Function: PNP/NPN adjustable, normally open/normally closed adjustable, hysteresis mode/window mode optional.

3. Analog parameter:

Output signal: 4... 20 mA or 0... 10 V (programmable switching).

Accuracy: ≤± 0.5% of full scale.

Scalable: The pressure values corresponding to 4 mA and 20 mA can be freely set within the full range (e.g. 4 mA=20 bar, 20 mA=80 bar), improving the sampling resolution of specific intervals.

IO Link intelligent communication interface

PN7271 integrates IO Link 1.1 communication protocol and is a core component for implementing Industry 4.0 and intelligent maintenance.

Communication speed: COM2 (38.4 kbps).

Process data: 16 digit pressure value+4-digit switch value/diagnostic status bit. Obtain high-precision digital pressure values directly without the need for analog modules.

Parameters that can be remotely written (non cyclic data):

Switch points SP1/rP1, SP2/rP2.

Output logic (normally open/normally closed, PNP/NPN).

The starting and ending values of analog quantities.

Display settings (damping coefficient, display direction, backlight color threshold).

Remote readable diagnostic data:

Peak pressure (the highest pressure since power on).

Pressure valley value (the lowest pressure since power on).

Temperature peak (the highest temperature experienced inside the sensor).

Run time counter (cumulative power on hours).

Data storage: Supports IO Link data storage function. When replacing the sensor, the main station automatically downloads the backup parameters to the new sensor, achieving plug and play and zero downtime waiting.

Summary of Core Advantages

High pressure resistance and long lifespan: measuring range of 100 bar, pressure resistance of 150 bar, and rupture pressure of 350 bar. Capable of withstanding frequent pressure shocks (water hammer effect) in hydraulic systems.

Washable design: IP 69K protection level, suitable for high-temperature and high-pressure flushing processes in industries such as food and pharmaceuticals.

Dual mode analog output: a rare flexible configuration in the industry, where one device serves two sets of acquisition systems, reducing hardware costs.

Intelligent diagnosis: Provides maintenance data such as pressure peak, temperature peak, and operating time to achieve predictive maintenance.

Digital integration: IO Link interface eliminates analog errors, supports remote parameter management and device asset management.
