FESTOAs an automation technology supplier, its pressure sensors are renowned for their high precision, reliability, and ease of use, and are widely used in industrial pneumatic systems, hydraulic equipment, and process control fields. This article will introduce the systemFESTOThe core functions, installation and debugging steps, and daily maintenance points of pressure sensors help users fully utilize equipment performance and ensure stable system operation.

1、 Analysis of Product Core Features

1. Range and accuracy adapt to diverse scenarios

FESTOPressure sensors offer multiple range options (such as-1~10barThe0~60barCovering industrial demands ranging from vacuum to high pressure. Its typical accuracy can reach±0.5%FS(Full scale percentage), supported by some models±0.1%FSThe high-precision output meets the strict pressure control requirements of industries such as semiconductor manufacturing and food processing.

2. Flexible and compatible output signal

Sensors support analog output (such as0~10VThe4~20mA）And digital communication interfaces (such asIO-LinkTheRS485）Can be seamlessly integrated intoPLCTheDCSOr industrial Internet of Things systems. among which,4~20mAThe signal has the advantages of strong anti-interference ability and long transmission distance, making it suitable for long-distance wiring scenarios.

3. Protection level and medium compatibility

The shell adoptsIP65/IP67Protective design, excellent dust and waterproof performance, suitable for harsh environments such as humidity and dust. The sensor diaphragm material can be selected from stainless steel, ceramic or polytetrafluoroethylene, compatible with air, water, oil and corrosive media, extending the service life of the equipment.

2、 Installation and debugging steps

1. Key points of mechanical installation

Location selection: Avoid installing near vibration sources or pipe bends to reduce measurement errors. It is recommended to install it in a horizontal straight pipe section, at least at a distance from the valve or pump5Double the diameter of the pipe.

Threaded connection: Use matching seals (such asPTFERaw material tape or metal sealing ring) to ensure no leakage. The tightening torque must comply with the specifications (such asG1/2Interface recommendation15~20N·m）.

Electrical wiring: The analog output terminal needs to distinguish between positive and negative poles, and the digital interface needs to be configured with terminal resistors (such asRS485Bus end).

2. Parameter configuration and calibration

Zero and range calibration: through sensor matching software orPLCProgramming tool, input the current environmental pressure value (such as atmospheric pressure) to complete zero calibration; Enter the standard pressure source value for range calibration.

Filter settings: For pulse pressure or high-frequency vibration scenarios, internal filtering functions can be enabled (such as10HzLow pass filtering is used to balance response speed and stability.

Diagnostic function enabled: Configure alarm thresholds for faults such as overvoltage and disconnection, and monitor sensor health status in real-time.

3、 Daily maintenance and troubleshooting

1. Regular inspection checklist

Appearance inspection: Confirm that the sensor is not corroded, deformed, or leaking.

Signal testing: Use a multimeter or upper computer software to verify the consistency between the output value and the actual pressure.

Cleaning and maintenance: Wipe the surface of the sensor with a soft cloth and avoid using chemical solvents.

2. Common fault handling

No output signal: Check the power supply voltage (usually24V DC）Check if the wiring is loose or replace the internal fuse of the sensor.

Large output fluctuations: Check for pipeline vibration, electromagnetic interference, or medium pulsation, and if necessary, add dampers or shield cables.

Display error exceeding limit: recalibrate the sensor or check if the pressure interface is blocked.

4、 Application scenarios and selection suggestions

Pneumatic system: Select range0~10barThe4~20mAOutput model, monitor compressed air pressure, and prevent abnormal cylinder operation.

Hydraulic equipment: choose high-pressure resistant (such as0~600bar）Stainless steel diaphragm sensor ensures stable oil pressure.

Food industry: prioritize hygienic design (such asIP69KProtection316LStainless steel material), meets the requirementsCIPCleaning requirements.

Conclusion: Precise perception empowers intelligent manufacturing

FESTOPressure sensors provide reliable pressure monitoring solutions for industrial automation through modular design, high-precision measurement, and intelligent diagnostic functions. Users only need to follow standardized installation, regular calibration, and reasonable selection to maximize equipment value and promote the upgrading of production processes towards efficiency and safety.
