Pressure Sensors  from Prime Controls Co.  Dynisco, Balluff Inc.

Dynisco invented the first transducer to successfully measure melt pressure during the extrusion process; all the others are copycats. They have been the industry leader for decades. Today they have the first and only transducer with the sensing in the head; no mercury, no fill, faster response, higher accuracy, longer life.

Balluff Inc., founded in 1921, is one of the world's leading sensor manufacturers. They offer a wide range of sensors using various technologies. This pressure transducer is Balluff's newest sensor.
