The process immersion fittings of the 202821 series are optionally equipped with an integrated sensor cleaning system. The fitting is designed for use of gel-filled sensors and is integrated into the respective process through a flange or a bracket. The standard version is available in stainless steel 1.4403/316L that is appropriate for the pharmaceutical industry.
Commercially available sensors with 120 x 12 mm installation dimensions and Pg13.5 thread can be installed in the fitting. The insertion length of the fitting is in the range from 500 to 2500 mm (500 mm steps in each case).
The optionally available integrated sensor cleaning allows an effective mechanical cleansing of the sensor through inflowing air or suitable irrigation fluid to take place. Thereby, reliable measurement is assured even in critical media. The flush can be activated through a cleaning or washing contact on the transmitter. A separate controller is not necessary in this case. The spray nozzles in the bottom section of the protection basket (which is part of the fitting) make effective cleaning possible.
