The POS movable fitting with a notched ring is an accessory designed for installation of temperature sensors with 3–8 mm diameters into thermowells, boreholes and various systems (gearboxes, bearings, etc.), and allows you to adjust a required immersion depth of the sensor in the measured medium. The movable fitting can be made of stainless steel of grade DIN 1.4301 (AISI 304), DIN 1.4571 (AIS 316Ti). The fitting consists of three parts – mounting fitting for securing in a measured point, a notched sealing ring and a cap nut to tighten the ring. The selected immersion depth cannot be changed anymore after the tightening. The inner diameter of the movable fitting is always bigger by 0.1–0.2 mm than the sensor diameter.
Sizes, materials and threads of the movable fitting can be changed if required by the customer.
