Pressure Sensors

Melt Pressure Transducers

Melt Pressure Transducers convert melt pressure into an electrical readout signal.


Gefran M3 Melt pressure transducers the mercury-filled melt pressure sensors, designed by Gefran on an extensometric technology, are suitable to work at high temperature, up to 400°C, assuring a total compliance with the maximum levels of accuracy and of reliability. These pressure sensors output at mV / V output. Theses sensors are also a drop in replacements for other brands. Give us a call for a quote.

Types of Melt Pressure Tranducers

  • Rigid stem configuration for fast, easy installation
  • Flexible configuration for applications requiring further thermal isolation or where installation would be otherwise difficult or impractical
  • Pressure/temperature configuration requires only one mounting hole for the measurement of both process values
  • Exposed capillary configuration fits in space-restricted locations


Melt Pressure Transducer configurations also available as

  • Oil-filled tranducers
  • Explosion proof transducers
  • Oil-filled
  • explosion Proof Sensors
