Melt Pressure Transducers operate on the proven principle of strain gauge technology. The pressure is transferred from the measuring diaphragm (which is flush with the melt channel) via a capillary system to a second diaphragm. The capillary system is filled either with mercury or with a mercury-free medium. The second diaphragm is fitted with a strain gauge. Using the linear change in resistance in relation to deflection, an electric output signal is provided. The special membrane technology guarantees a very long operating life, even under the toughest conditions. The anti-adhesion coating reduces the risk of damage caused by frozen plastic melts.

DA Series	The DA Series melt pressure transducers are characterized by their high quality of workmanship and outstanding performance and are used in the plastic manufacturing and processing industries throughout the world. Their absolute reproducibility and stable measuring values contribute to our measurement accuracies.
DAI Series	The DAI Series offers – in addition to maximum reliability – improved user friendliness in the form of an Auto-Zero Function for local or remote configuration. These models offer mA and mV output signals for further processing. The popular and most commonly used 2-wire and 4-20mA configuration provide unequalled interference in critical environments.
DTA Series	The DTA melt pressure sensor series combines the standard DA and temperature measurement into one unit. The DTA impresses through its ruggedness and reliability as well as its exceptional cost efficiency. The DTA allows for direct measurement of pressure and temperature at one measuring point of the process.
DTAI Series	The DTAI offers the comfort of the DAI series combining temperature measurement into one unit. The Auto-Zero function allows a calibrating of the instrument to be performed either locally or remotely / via a controller. The melt pressure transmitter provides an AM or Voltage signal for further processing.
DAP Series	The DAP Series incorporate a heated sensor tip, which limits the potential for sensor damage relating to the membrane, resulting from installation or removal of the pressure transmitter. The Gneuss patented heated sensor tip allows the sensor to be easily removed from a “frozen” melt without any problems.
DAIP Series	The DAIP Series offers the comfort of the DAI series in conjunction with a heated sensor tip. Thus eliminating the most common reason for sensor faults: the damaging of the membrane on installation or removal of the sensor. The patented heated sensor tip allows the sensor to be removed from the frozen melt without any difficulty.
DAIX	With the DAIX Series, Explosion proof pressure transducer are available. This melt pressure transducer is intrinsically safe. The uncompromising development of the DAIX provides an excellent choice for Ex-areas,
