Variable depth temperature sensor PW1/2

The BBL temperature sensor PW1/2 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 results in excellent measuring results without any losses in stability. BBL is the original manufacturer of this well-proven and globally used temperature sensor.
