Manual Retractable Fittings SensoGate W M Manual retractable fitting with safe-to-operate rotary drive Revolutionary operation The SensoGate W M has a manual rotary drive, which enables the fitting to be operated up to a counter pressure of 45 psi ( bar) and this in less than two rotations. Regardless of how unfavorable the angle or the operating height at which the fitting is installed. Little rotary force is required and is easily applied manually. This is not possible with the sliding motion of conventional retractable fittings. Maximum process safety The configuration of the O-rings means that there is never any connection between the drain opening of the cleaning chamber and the process, even during inward and outward movement of the sensor. For maximum process safety, the sensor can only be removed in the service position. utomatic insertion protection reliably blocks the movement of the fitting and prevents extension into the process position without a sensor. Facts ompact, buildup resistant design Low maintenance Simple replacement of seals due to divided calibration/cleaning chamber Increased service life and reduced seal wear TEX approval II G c II for the complete fitting Low cost, simple installation, operation, and maintenance SensoLock for high operational safety Integrated limit switches Fast and easy replacement of calibration chamber and insertion tube ll maintenance can be performed on site yclone cleaning effect Standard sensor length (5 mm) even for large immersion depths Multiple process connections available Flange version with scraping ring Modular design allows specific replacement of the process-wetted materials: PEEK, PVF, PP, 6 SS, Hastelloy Plastic versions with high pressure and temperature resistance due to carbonfiber-reinforced plastics Special version for sensors with pressurized liquid electrolyte 56
