Model 65Q Pt100 Model 65Q Pt 100 Temperature Sensor for Hygienic and Direct Insertion Applications Rosemount Series 65Q RTD temperature sensors are designed for use in hygienic applications when fitted with the Tri-Clamp mounting. Alternatively, for direct insertion into non-hygienic processes the 65Q can be ordered with the optional ½-inch NPT or ½-inch BSPF thread mounting.
Accuracy
The 65Q sensor consists of a mineral-insulated measuring insert, wherein a wire-wound ceramic RTD-element is encapsulated. The platinum element is firmly secured within the sheath by compacted magnesium oxide. This construction protects the relatively strain-free element, thereby maintaining accuracy and long-term stability. The sensor is mounted into a swaged AISI 316Ti (1.4571) sheath.
