This document introduces the Smartec S CLD132 measurement system manufactured by Endress+Hauser, which is used for conductivity and concentration measurement in the food industry. The system features a stainless steel housing, high-strength plastic sensor, sterilizable sensor, self-monitoring function, insensitivity to polarization and contamination, etc. It is suitable for monitoring of brewing, dairy and beverage industry products, CIP system control, phase separation in pipeline systems, acid and alkali concentration control, and monitoring of bottle cleaning systems.
The CLD132 measurement system is designed for monitoring products in brewing, dairy and beverage production, CIP control, phase separation in pipelines, acid/base concentration control and bottle‑wash monitoring. It features a stainless‑steel housing, a PEEK‑based hygienic sensor, self‑monitoring functions and resistance to polarization and fouling.
The device provides multiple communication options (HART handheld terminal, PROFIBUS PA/DP, PC software), a large two‑line display, optional temperature current output, and a range of accessories such as extended cables, VBM junction boxes and installation kits. It operates over a wide temperature range (‑35 °C to +250 °C) and offers fast temperature response (t90 < 5 s). This manual is written in Chinese.
