Robertshaw Model 352 Conductivity Switch 352‑B2
The Robertshaw 352-B2 Conductivity Switch is a precision industrial sensor designed to monitor the conductivity (and thus presence or absence of conductive fluid) within process systems — making it ideal for applications such as fluid level detection, leak detection, boiler water monitoring, or chemical processing where conductivity-based switching is required. Engineered for reliable operation in harsh industrial environments, this switch offers robust construction, dependable performance, and seamless integration with control or safety logic systems.
Key Features:
Conductivity‑based switching mechanism — ideal for detecting conductive liquids, fluid presence, or fluid absence in process tanks, boilers, or pipelines.
Durable industrial-grade construction suitable for harsh environments including chemical processes, water treatment, or boiler systems.
Reliable and repeatable switching action to provide consistent fluid detection and process safety or control functions.
Compatible with standard industrial control circuits — enabling easy integration into automation, safety, or alert systems.
Low maintenance design for long-term use, reducing downtime and maintenance overhead in industrial setups.
Specifications:
Manufacturer Part Number: 352‑B2
Device Type: Conductivity Switch / Sensor for fluid conductivity detection
Sensing Principle: Conductivity measurement — detects presence or continuity of conductive liquid between electrodes to switch output signal
