IFM PI2797

The PI2797 is a flush pressure sensor with display from ifm that excels in areas such as industrial pressure monitoring and provides key support for the stability and efficiency of production processes.

1. Product design characteristics
Rugged stainless steel shell: The shell is made of high-quality stainless steel, which has excellent strength and durability, can withstand physical impact such as collision and friction in harsh industrial environments, effectively protect internal precision components, and ensure long-term stable operation, especially suitable for scenarios with high requirements for equipment reliability such as the food and beverage industry.

Hygienic flush design: The flush design makes the sensor surface free of grooves and gaps, avoids medium residue and accumulation, and greatly reduces the risk of bacterial breeding. This hygienic design meets the strict hygiene standards of the food, beverage, pharmaceutical and other industries, and is easy to clean and disinfect, effectively ensuring product quality and safety.

Resistant to high-pressure cleaning and chemical corrosion: PI2797 is not afraid of aggressive cleaning agents and high-pressure cleaning operations. Its special material selection and process treatment make it resistant to such harsh cleaning environments, ensuring that the performance of the sensor is not affected during frequent cleaning and maintenance, maintaining normal working conditions and prolonging the service life of the equipment.

2. Electrical performance parameters
High-precision measurement: In terms of pressure measurement, the accuracy can reach ±0.2% (full scale). This means that in a variety of complex industrial environments, it can accurately sense pressure changes and output accurate data, providing a reliable basis for industrial process control, such as in chemical reactor pressure monitoring.

High Resolution: The resolution is excellent, with the ability to keenly capture even the most subtle pressure changes. Whether it is in the precision production process with small pressure fluctuations, or under complex working conditions with a large range of pressure changes, it can ensure the accuracy of data acquisition and provide strong support for the fine control of equipment.

High-speed conversion and response: With fast conversion speed, it can convert the pressure signal into digital signal output in a very short time, and the response time is fast, which can meet the strict requirements of real-time data acquisition and processing on the high-speed production line. For example, in high-speed filling lines, pressure can be monitored in time to ensure the accuracy and consistency of filling volumes.

Wide voltage range: The supported working voltage range is 18 - 32V DC, which makes it better match with industrial equipment with different power supply specifications, and can operate stably in different power supply environments, reducing the risk of equipment failure caused by voltage mismatch.
Electrical protection function: Built-in multiple electrical protection mechanisms such as inverted phase protection, short circuit protection and overload protection. When there is an abnormal situation such as reverse polarity of the power supply, short circuit circuit or load overload, the protection function can be quickly started to avoid damage to the internal circuit of the sensor and improve the safety and reliability of equipment operation.

3. Input and output configuration
Digital output: Equipped with two digital output channels, the switching signal can be output according to the preset pressure threshold. These outputs can be flexibly programmed to trigger corresponding control actions when the pressure reaches or exceeds a certain value, such as opening and closing the control valve, starting or stopping the motor, etc., to achieve automatic control of industrial processes.

Analog Output: Featuring an analog output channel that outputs a standard 4 - 20mA current signal (scalable). The analog signal can continuously and accurately reflect the actual measured pressure value, which is convenient for seamless connection with various industrial control systems and data acquisition equipment, and provides detailed pressure data for the system for further analysis and processing.

. IO-Link communication interface: Supports IO-Link communication protocol, an advanced industrial communication standard that allows bidirectional, high-speed data transmission between sensors and host computers. Through the IO-Link interface, it can not only realize remote configuration and parameter adjustment of the sensor, but also obtain the working status and diagnostic information of the sensor in real time, which greatly improves the convenience and intelligence level of equipment management and maintenance.

4. the measurement range and pressure type
Flexible measuring range: pressure measuring range - 0.05...1 bar (-50... 1000 mbar, -0.73...14.5 psi, -5...100 kPa), this wide and flexibly switchable measuring range makes it suitable for a wide range of industrial applications, from micro pressure monitoring to large pressure measurement, such as micro pressure experiments in the laboratory, routine pressure detection in industrial pipelines, etc.

Relative pressure measurement: It is mainly used to measure relative pressure, that is, to measure the difference between the pressure of the target medium and the atmospheric pressure with the local atmospheric pressure as the reference reference. In many industrial processes, the measurement of relative pressure plays a crucial role in ensuring the stable operation of production processes, the safe operation of equipment and the control of product quality, such as pressure monitoring in ventilation and hydraulic systems.

5. Application scenarios
Food and beverage industry: With its hygienic flush design and cleaning resistance, it is widely used in all aspects of food and beverage production. It can be used to monitor the pressure during the liquid filling process to ensure that each bottle is filled accurately and consistently; In the pipeline transportation link, real-time monitoring of pressure changes, timely detection of pipeline blockage, leakage and other problems, to ensure the continuity of production and product quality and safety.

Pharmaceutical industry: In the process of drug production, the hygienic requirements for the environment and equipment are extremely high. PI2797 can be used for pressure monitoring in clean rooms, maintaining positive or negative pressure environments in the room to prevent external contaminants from entering; In terms of liquid medicine transportation and reactor pressure control, it can also give full play to its advantages of high-precision measurement and reliable performance to ensure that the drug production process meets strict quality standards.

Chemical industry: chemical production is often accompanied by complex working conditions such as high temperature, high pressure and strong corrosive media. The characteristics of the sensor, such as corrosion resistance, high temperature resistance and wide measurement range, make it suitable for chemical pipeline pressure monitoring, reactor pressure control and other scenarios, and can work stably in harsh environments, providing accurate data support for the safe and stable operation of chemical production processes.

Other industrial fields: in automobile manufacturing, electronic equipment manufacturing and other industries, it can also be used for pressure monitoring of equipment lubrication system and cooling system, timely detection of potential system failures, ensure the normal operation of equipment, and improve production efficiency and product quality. At the same time, in some automated production lines that require precise pressure control, PI2797 can accurately sense pressure changes, provide reliable feedback signals for the automatic control system, and achieve accurate control of the production process.
