Applications
■Melt pressure control of extruders
RPM of main motor is controlled to maintain constant melt pressure (discharge rate).
- Uniform discharge rate improves quality of extrusion molded products.
Typical models
Digital melt pressure controller
HA930
- Measurement accuracy: ±0.1% of displayed value
- Sampling time: 0.025 sec.
- Strain gauge type melt pressure sensor can be connected
- Pressure and temperature control can be performed on a single controller
- Plug-in construction
Melt Pressure Sensor
CZ-200P
- Pushrod system which provides no risk of resin contamination when the sensor is damaged.
- The optional built-in thermocouple type can measure resin pressure and temperature simultaneously.
- Various types are available, including highly accurate type which enables overall accuracy of 0.5% FS.
- Optional Spron diaphragm which enables measurement up to 550°C.
