1. Product Overview
The Endress+Hauser COS61-A1FO is a high-precision industrial conductivity sensor engineered for demanding process applications requiring hygienic design and corrosion resistance. Featuring a four-electrode measurement principle with FEP-coated titanium body (A1FO suffix), this sensor delivers uncompromised accuracy in aggressive media while preventing fouling. Its Hygienic 3-A/SMS clamp connection enables CIP/SIP compatibility for pharmaceutical and food processing. The sensor operates across an exceptional -40°C to +130°C temperature range with 316L stainless steel process fittings rated to 16 bar. Integrated Pt1000 temperature compensation ensures ±0.5% measurement accuracy. Designed for SIL 2 applications per IEC 61508, it includes Memosens digital technology for plug-and-play calibration and predictive diagnostics. The optical Memosens interface eliminates moisture issues and enables pre-calibrated sensor replacement without process interruption.
