Retractex C Manual or Pneumatic Retractable Housing
Versatility, Even in Demanding Chemical Applications
Retractex C is a retractable sensor housing designed for chemical industry applications, supporting process pressures up to 16 bar. Stainless steel and plastic models are available for exceptional durability and chemical resistance, each with manual or pneumatic retraction. Additionally, various process connections and sealing materials support maximum flexibility.
The Retractex C is ideal for cleaning sensors in live processes within chemical plants. With its retractable design and built-in PTFE scraper, the sensor can be cleaned without disrupting operations, ensuring accurate readings and minimizing downtime. This allows for continuous monitoring and enhances process safety and efficiency, making it a reliable choice for demanding environments.
The Retractex C houses 225 mm sensors with a 12 mm shaft diameter, including our sensors for process analytics, and features a short stroke of 36 mm for low seal wear and high reliability.
Safeguarding Processes and Users
The patented cleaning design allows thorough in-place cleaning, including the space between the socket and rinsing chamber, to increase process efficiency. Retractex C includes safety features such as “no sensor – no insertion” and a leakage-check window for visual inspections.
