high-resolution pressure sensors for enhanced industrial applications

At the core of the new pressure sensors is an extremely robust ceramic measuring cell that ensures long-term stability, even under high pressure peaks, overloads, or exposure to abrasive media. Unlike conventional metallic diaphragms, the ceramic cell eliminates the need for oil as a transfer medium, minimising contamination risks and ensuring maximum safety in hygienic environments. This innovation meets stringent industrial and regulatory demands, enhancing reliability across critical operations.

The sensors feature advanced diagnostic functions and continuous monitoring of the status of the measuring cell. This ensures operational confidence and supports compliance with requirements of sensitive processes. An intelligent dynamic temperature compensation algorithm addresses challenges caused by rapid temperature fluctuations, delivering precise and stable measurements.

Optimised for efficiency, the PI series offers high-resolution data transmission with approximately 20,000 steps via IO-Link. This capability ensures loss-free digital transmission of pressure and temperature values, enabling greater process transparency and seamless integration into Industry 4.0 environments. IO-Link also facilitates convenient sensor configuration and diagnostics, reducing setup time and enhancing operational readiness.

The PI series comes with a fully welded 316L stainless steel housing that resists aggressive chemicals and high-pressure cleaning, making it suitable for demanding environments like dairies and beverage production facilities. The sensor design includes an optimised ventilation system to prevent moisture ingress, reducing the risk of inaccuracies from reference pressure errors.

These pressure sensors excel in real-world applications such as hydrostatic level measurement in tanks, pressure monitoring in pipes, and fermentation processes. Industries benefit from increased system availability and minimised downtime. For example, food producers can reduce delays during cleaning cycles, as the sensor's integrated temperature compensation achieves stable readings up to 60 seconds faster than conventional models.

ifm's new PI series exemplifies a commitment to precision, efficiency, and innovation, offering substantial improvements for processes where accuracy and hygiene are paramount.
