IO-Link pressure transmitters

• Pressure measuring accuracy 0.3%, 0.5%
• Media temperature measurement
• Excellent long-term stability
• COM3, min. process cycle time 1ms
• 2 Switching outputs PNP/NPN/Push-Pull configurable
• Optional: 5-fold overpressure resistance

The NAI 8273 IO-Link pressure transmitter is designed as a smart sensor and provides application-relevant diagnostic functions and recorded information in addition to the process data for condition monitoring and predictive maintenance. The process data contains the pressure value and the media temperature value, which is measured directly at the exceptionally long-term stable thin-film-on-steel pressure sensor cell with triple (optionally 5-fold) overpressure protection.

Thanks to the built-in powerful microcontroller, the sensor can communicate with the maximum available IO-Link data transmission rate of 230.4kBaud respective COM3. This enables a minimum cycle time of 1ms and thus the system receives current process values at very short intervals for best response times.

The small and smart pressure sensor combined with available measuring ranges from -0.2 ... 0.2 to 700bar with a pressure measuring accuracy of ±0.5% FS or ±0.3% FS make the NAI 8273 the ideal choice in various industry 4.0 applications.

For the use of conventional switching outputs, the polarities NPN, PNP and Push-Pull are configurable.

What is IO-Link and its features?

IO-Link is an established digital communication standard for smart sensors and actuators in various applications. As an open standard according to IEC 61131-9, IO-Link is a fieldbus independent technology for point-to-point communication. With its simple connection and standardization of communication as well as integrated intelligence, IO Link offers users supporting functions for system integration, operation, service and maintenance.

The distribution of IO-Link is growing continuously, and the advantages of IO-Link are appreciated.

• Simple and efficient system integration and commissioning with parameterization by the IO-Link master
• Reduced costs and simplest standardized wiring due to unshielded three-core cables
• Error reduction through digital signal transmission
• Diagnostic information to support service and maintenance
• Easy device replacement through automated storage of parameters
• Backward compatible with conventional digital sensors through SIO PNP and NPN
