Description
The SensoGate WA 131 H is a pneumatic retractable holder for 225 mm pH, ORP, conductivity, and oxygen sensors. The retractable holder connects to a CL-90 simple cleaning system or other commercially available controllers for automatic or semi-automatic sensor retraction. The fitting has FDA-certified process-wetted parts, including the rinsing/calibration chamber.
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 sanitary process fittings, materials of construction, electropolishing, and elastomer materials, you can be sure to choose the correct holder in all applications.
The SensoGate series of holders is the first retractable fitting featuring a sealing water function with a lock-gate. The gasket rinsing during the stroke movement – from measurement to the service position and back – reliably prevents the adherence of dirt, fibers, and particles. This feature results in a much longer service life with correspondingly reduced maintenance requirements and significant cost savings.
The SensoGate WA 131 H has both an inlet and outlet to bring cleaning solutions into the chamber. In addition, the SensoGate utilizes a “cyclone cleaning” process that dispurses rinse media 360° around the sensor for a thorough cleaning.
A SensoGate WA 131 H is the ideal sensor holder for processes where:
- Easy access to a sensor during operation is required
- Hazardous materials cause safety concerns
- Suspended solids require regular sensor cleaning
- Process shutdowns require wet storage of sensors
- CIP and SIP cleaning are required
