Sanitary RTDs


Standard sanitary assemblies include a proven thin film PT100 platinum RTD sensing element, packaged in an all welded 316L stainless steel probe. Configurations feature Tri-Clover® fittings and surface finishes that comply with 3A Standard Number 74-06 for food, dairy, beverage, pharmaceutical and chemical processing applications. A compact programmable transmitter can also be built into the probe assembly.
