The IFM SI6800 is a hygienic flow and process monitoring sensor designed for industries where sterility, safety, and precision are paramount. Engineered for use in hygienic systems, it is ideally suited for applications in food and beverage production, dairy operations, brewing, and pharmaceutical manufacturing. Its rugged construction, compliance with hygiene standards, and broad performance range make it a trusted choice for demanding environments.

The sensor is designed to function reliably in processes involving liquids and gases, and it offers a maximum allowable working pressure (MAWP) of 30 bar, compliant with CRN (Canadian Registration Number) requirements. This ensures safe operation even under pressurised conditions, providing operators with confidence in both performance and durability. The ability to handle elevated pressures expands its application scope, from pipeline monitoring to pressurised tank systems.

Thermal resilience is another strength of the SI6800. The device performs reliably within a medium temperature range of -25 to 95 °C for normal operation and can tolerate sterilisation-in-place (SIP) cleaning processes up to 140 °C. This makes it perfectly suited to environments requiring frequent cleaning and sterilisation to maintain hygiene standards. The robust temperature capability ensures long service life and accurate monitoring even when subjected to repeated SIP cycles.

From an electrical perspective, the SI6800 offers a wide operating voltage range of 19…36 V DC, making it compatible with standard industrial power supplies and easy to integrate into existing automation systems. With a current consumption of less than 60 mA, the sensor delivers energy-efficient operation that reduces system load, particularly valuable in facilities deploying multiple monitoring devices.

The SI6800 is also designed with strong safety features. Protection class III ensures safe operation under extra-low voltage conditions, while reverse polarity protection prevents damage from incorrect wiring during installation. These features contribute to long-term operational reliability and minimise downtime caused by electrical faults.

In practice, the SI6800 supports accurate real-time monitoring of process conditions, enabling operators to detect irregularities such as pressure drops, flow disruptions, or leaks early on. Its hygienic design ensures compliance with food and pharmaceutical standards, while its ability to withstand aggressive cleaning and pressurised environments provides confidence in continuous, safe operation.

In summary, the IFM SI6800 is a hygienic, high-performance sensor that combines 30 bar pressure resistance, extended temperature tolerance, and robust electrical safety into one compact unit. Designed for industries where both hygiene and reliability are non-negotiable, it offers dependable monitoring for liquids and gases under a wide range of conditions. Whether deployed in beverage bottling, dairy production, or pharmaceutical processing, the SI6800 ensures consistent performance, regulatory compliance, and process efficiency.
