Temperature sensor DD28/20

The BBL temperature sensors DD28/20 is suitable for precisely measuring and controlling mass temperature in the drop door (saddle) of internal rubber mixers. Due to its unique geometry these sensors are extremely robust and therefore perfectly suited for rubber and tire industry mixing applications, respectively. The DD302 is used in rubber plants worldwide and regarded as industry standard by leading tire manufacturers.
