Variable depth temperature sensor PW18

The BBL temperature sensor PW18 is suitable for precisely measuring and controlling mass temperature during plastic or rubber extrusion. Its adjustable insertion depth allows spatial determination of mass temperature within the mass current. The PW has a complex construction with high-quality components especially suited for high force and high temp applications. This enables excellent measuring results without any losses in stability. BBL is the original manufacturer of this well-proven and globally used temperature sensor.
