The SensoGate WA 131 M is a manual retractable holder for 225 mm pH, ORP, conductivity, and oxygen sensors. The retractable holder has a manual rotary drive that operates in a counter-pressure of up to 145 psi (10 bar) with little force from the user.

SensoGate WA 131 M 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 SensoLock function prevents process leak paths, even if the holder contains an improperly installed sensor. Furthermore, 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 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 of wear parts with correspondingly reduced maintenance requirements and significant cost savings. You can configure the SensoGate WA 131 M with both 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.  

Applications for the SensoGate WA 131 M

A SensoGate WA 131 M is the ideal sensor holder for processes where:

• Easy access to a sensor during operation
• Hazardous materials cause safety concerns
• Suspended solids require regular sensor cleaning
• Process shutdowns require wet storage of sensors
