Platinum thermal resistance temperature sensor WZPM2-08-75-M18-8 requires on-site flow temperature measurement in many situations according to process requirements. The WZPM2-08 series surface thermal resistance is the latest product designed according to the above process requirements and used in conjunction with digital displays. The platinum resistance temperature measuring head is made of imported platinum resistance components, which has the advantages of accuracy, sensitivity, fast thermal response time, stable quality, and long service life.
