What it solves
In extrusion, injection molding and industrial lines, process pressure is a critical variable for equipment protection, product quality and early detection of deviations. A Dynisco® pressure transducer converts real process pressure into an electrical signal for indicators, alarms, PLC or SCADA systems.
Process control
Stable readings to detect pressure changes, filter clogging and viscosity variations.
Equipment protection
Early alarms to protect pumps, filters, dies and critical process components.
Product quality
Improved repeatability to reduce scrap and maintain uniform production.
Operating principle
The melt pressure acts on a diaphragm. The diaphragm deformation is proportional to the applied pressure and is detected by a strain gauge. The instrument then provides an output signal such as mV/V, 4-20 mA or Vdc depending on the selected model.
Typical applications
Common locations in extrusion include the barrel, filter, before and after the pump, and the die. Each point helps diagnose process conditions, detect clogging, protect equipment and stabilize flow.
Selection data
- Maximum and normal operating pressure.
- Material temperature and diaphragm area temperature.
- Existing thread or mechanical connection.
- Stem length and available space.
- Output signal: mV/V, 4-20 mA, 0-10 V or other.
- Electrical connector, cable, environment and certifications.
For replacements, a photo of the installed transducer or nameplate helps identify range, thread and output signal.
