Customer benefits

  • Uncomplicated and economical
    To date, melt pressure transmitters were typically used with a 2 mV/V or 3.3 mV/V output signal. On the control side, however, this requires either special signal inputs or an additional measuring amplifier for the conversion to a standard signal. Thanks to the use of new electronics, the melt pressure transmitters from JUMO are optionally available with an analog 4..20 mA standard signal or with a digital CANopen signal. This allows the probes to directly connected to the generally used standard or fieldbus signals of control systems and display devices, and results in lower cost controls, simplifies installation and creates more space in the switch cabinet.
  • environmentaly friendly
    The NAK (sodium-potassium) filling medium is a real alternative to conventional mercury. NAK is a liquid an environmentally sound, non-toxic alloy.


  • Plastics processing
  • Processing technology
  • Chemistry


The melt pressure transmitters of type 4 ADM-35 can be used in the plastics processing industry as well as in processing technology, predominantly for recording the pressure of liquid, dough- or paste-like mass in extrusion machines. Such applications require the transmitters to be particularly robust. For this reason, they are suitable for measuring ranges from 50 bar to 2000 bar and for medium temperatures up to 480°C.
