Temperaturse sensor DD222, DD272 und DD302

Our well-established BBL temperature sensors DD302, DD272, and DD222 are 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/tire industry mixing applications. The DD302 is used in rubber plants worldwide and regarded as industry standard by leading tire manufacturers.
