Melt Pressure Transducer Tip Spacers

  • Melt pressure transducer tip spacers – to recess tip
  • M18x1.5 to ½-20UNF thread adaptors

MPI melt pressure transducer/transmitter tip spacers or shims are often used on old extruder barrels where sensor tips are protruding into the melt stream. Transducer tips should be recessed from the inner extruder barrel wall by approximately 0.010”-0.020” to prevent excessive wear and early failure of transducer diaphragms. Our tip spacers / shims essentially push the diaphragm back from the inner wall, as shown in the diagram.

Melt Pressure Transducer Tip Spacer / Shim Features

  • Compatible with Dynisco, Gefran, GP50, and other melt pressure transducers and transmitters
  • Available in thicknesses from 0.020” to 0.093”
  • Material options: copper, brass, stainless steel
 

Thread Adaptors: M18x1.5 to ½”-20UNF

MPI melt pressure transducer/transmitter thread adaptors can be used in an emergency to convert a metric M18x1.5 thread for use with a standard stock transducer with ½-20UNF thread.
