Description
The Ceramat WA 154 is a pneumatic retractable holder for 225 mm pH, ORP, conductivity, and oxygen sensors for long immersion depths. The retractable holder connects to the Unical or Uniclean controller for sensor retraction with automatic calibration and/or cleaning.
Ceramat WA 154 Focuses on Operator Safety
This holder offers several features focused on the safety of the operator. An internal scraping ring and “cyclone” cleaning chamber ensure minimal process media exposure.
In addition, the operator can only remove the sensor in the service position, maximizing process safety. Automatic insertion protection reliably blocks the movement of the fitting and prevents extension into the process position without a sensor.
Because of the variety of process fittings, materials of construction, and elastomer materials, you can be sure to choose the correct holder in all applications.
Built with Maintenance in Mind
The Ceramat series of holders utilize a unique lock-gate principle. Two planar ceramic disks rotate toward each other to seal the calibration chamber from the process. Ceramic sealing is highly resistant to chemical, thermal, and mechanical influences.
The retractable fitting has no-wear process sealing and modular construction that allows the drive to be removed entirely for sensor adjustment, cleaning, or replacement during the ongoing process. When used in conjunction with Knick automatic cleaning and calibration systems, the Ceramat provides maximum measurement uptime with minimum maintenance effort.
The Ceramat WA 154 has both an inlet and outlet to bring cleaning solutions into the chamber. In addition, the Ceramat utilizes a “cyclone cleaning” process that dispurses rinse media 360° around the sensor for a thorough cleaning.
Finally, the retractable holder includes a plug & play media adapter for quick installation to the Unical or Uniclean controller. The centralized multi-plug is a single connection to all rinsing, cleaning, and calibration media as well as the control air and limit position mechanisms.
Applications for the Ceramat WA 154
A Ceramat WA 154 is the ideal sensor holder for processes where:
- Highly viscous, abrasive, fibrous, or clogging process media are present
- Longer immersion depths are required
- Hazardous materials cause safety concerns
- Suspended solids require regular sensor cleaning
- Process shutdowns require wet storage of sensors
- Automatic calibrations and/or cleaning systems are required
