| WZCM、WZPM series end face thermal resistance elements are made of specially treated wire and closely attached to the thermometer end face. Compared with the general axial thermal resistance, it can be more correctly and quickly response the actual temperature of measured end face, and is suitable for measuring the end face temperature of bearing shell or other parts. |
