IFM SI6700 Hygienic Flow Monitor 3-300cm/s PNP G1 IP67/IP69K

Overview
The IFM SI6700 (SIR11ABBFPKG/US-100-IPF) is a hygienic flow monitor designed for precise flow detection in liquid and gaseous media within the food and beverage industry. Utilizing the calorimetric measuring principle, this monitor delivers reliable switching signals based on flow velocity, unaffected by pressure or temperature variations within specified limits. The hygienic design features a stainless steel (316L/1.4435) housing with electropolished wetted parts (Ra < 0.4 / Rz 4), meeting EHEDG sanitation standards. Suitable for SIP processes up to 140 °C and rated IP67/IP69K, the device withstands high‑pressure, high‑temperature washdowns and sterilisation cycles. The 10‑segment three‑colour LED bar graph provides clear visual indication of switch point and current flow status, while push‑button adjustment enables quick on‑site setup. With a wide media temperature range of -25…95 °C, pressure rating of 30 bar, and gold‑plated M12 connector contacts, the SI6700 delivers robust performance in demanding hygienic applications including CIP/SIP processes, pump protection, and cooling circuit monitoring.

Key Features

• Original brand new, within warranty period – Factory‑sealed, genuine IFM component with full manufacturer warranty.

• 100% Satisfaction Guarantee – Risk‑free purchase; if you are not completely satisfied, we will replace or refund.

• Hygienic design for food and beverage industry – Stainless steel (316L/1.4435) wetted parts with electropolished surface finish (Ra < 0.4 / Rz 4), meeting EHEDG sanitary standards for food, beverage, and pharmaceutical applications.

• Suitable for SIP processes up to 140 °C – Designed for sterilisation‑in‑place (SIP) processes with media temperatures up to 140 °C, while maintaining standard operation from -25…95 °C for CIP and normal processing.

• LED bar graph for switch point and flow indication – 10‑segment three‑colour LED bar graph provides clear visual indication of current flow velocity relative to the set switch point, simplifying commissioning and real‑time monitoring.

• Dual‑media compatibility (liquids and gases) – Monitors liquid flow (3…300 cm/s, greatest sensitivity 3…100 cm/s) and gas flow (200…3000 cm/s, greatest sensitivity 200…800 cm/s) in a single device, reducing inventory complexity.

• PNP switching output with NO/NC programmable – Single digital PNP output (250 mA continuous rating) programmable as normally open or normally closed, offering flexible integration into control systems. Parameterisable via push‑button or IO‑Link.

• Extensive range of process adapters – G 1 Aseptoflex Vario process connection accepts a wide range of hygienic adapters (weld‑in, clamp, thread) for flexible installation into various tank and pipeline configurations.

• Robust IP67/IP69K stainless steel housing – IP67 protection for dust‑tight and temporary immersion, plus IP69K for high‑pressure, high‑temperature washdown resistance, ensuring reliable operation in hygienic and wet areas.

• High reliability with 298‑year MTTF – Exceptional mean time to failure of 298 years ensures long‑term dependable operation, minimising unplanned downtime and maintenance costs. Gold‑plated contacts provide corrosion‑resistant signal transmission.
