Melt Pressure Transducers are an electronic device that transforms a physical variable (pressure) into an electrical signal, acquired by the various control, measurement and regulation devices. Their high immunity to electromagnetic interference allows these sensors to be installed in any operating environment.

K3 Series
The K3 Series are pressure sensors for use in high temperature applications where the process temperatures may reach 538°C (1000°F).The K3 Series utilizes standard melt pressure principles and construction; strain sensing technology is bonded foil strain gauge. A sodium-potassium mixture is used for pressure transmission. NaK is FDA recognized safe (GRAS) substance.
M3 Series
The M3 series of Gefran, are pressure transducers for using in High temperature environment. The main characteristic of this series is the capability to read temperature of the media up to 400°C. The constructive principle is based on the hydraulic transmission of the pressure. The fluid-filled system assures the temperature stability. The physical measure is transformed in a electrical measure by means the strain-gauge technology.
ME Series
The ME series of Gefran, are pressure transmitters for using in High temperature environment. The main characteristic of this series is the capability to read temperature of the media up to 400°C. The constructive principle is based on the hydraulic transmission of the pressure. The fluid-filled system assures the temperature stability. The physical measure is transformed in a electrical measure by means the strain-gauge technology.
M5 Series Pressure Gauge
The Gefran Melt Pressure Gauge provides reliable, maintenance- free, localized pressure indication. The small capillary tube filled with a special medium isolates the gauge housing from potential thermal damage. All models are rugged, totally self-contained, and allow the user to benefit from the improved efficiency and quality that goes with pressure monitoring.

Mount Hole Drill Kit
A properly machined mounting hole is vital to optimal operation of a melt pressure transducer or transmitter. Poorly machined holes can result in damage that causes unreliable output or even total failure. Transducer mounting hole drill kits contain the necessary drill bits and taps needed to machine a standard transducer mounting hole, including a special pilot drill required to machine the 45 degree seat. Drill kits are available for the 1/2-20 mounting hole (KF12). For the M18x1.5 mounting hole (KF18), please contact us for pricing and availability.
Mount Hole Cleaning Kit
The Cleaning Tool Kit is used to remove excess plastic from transducer mounting holes prior to installation. Installation of transducers into plugged and/or dirty mounting holes is a major cause of installation-related damage. The Cleaning Tool Kit allows the mounting hole to be properly cleaned and checked for integrity. Cleaning tools are available for 1/2-20 mounting holes (CT12) and M18x1.5 mounting holes (CT18).
Note: The cleaning tool should be used when the polymer is molten. Care must be taken not to exceed the specified torque rating (125 inch-pounds) so as to not.
