The products on this page were specially developed for plastics industry applications, such as:
- Extruders (resin pressure & temperature control)
- Injection molding (mold temperature verification & control)
- Hot runners (temperature control of many controlled heating zones)
Dedicated sensors for resin pressure & temperature
Resin temperature sensors
The T-270Z series resin temperature thermocouples are specially designed for high accuracy resin temperature measurement in extruders.
- suitable for high accuracy measurement of resin temperature in extruders
- zero heat flow measurement method eliminates thermal disturbance and temperature error between tip and case. This enables a more precise resin temperature measurement
Resin pressure & temperature sensors
The CZ100P & CZ200P series resin pressure & temperature transducers are specifically developed for extruder applications.
- CZ-100P: resin pressure only transducer
- CZ-200P: resin pressure & temperature transducer
Dedicated sensors for mold temperature
The temperature of the mold must be monitored to verify if it has the correct process-temperature. Sometimes the available measurement space is very small. RKC developed the ST-50/ST-51 ultra-compact film-type temperature sensors that can be easily attached to the mold with the STM-A magnetic holder.
- suitable for accurate measurement of mold temperature
- sensor type: type K thermocouple
- temperature range:
- ST-50: 0°C to +300°C
- ST-51: -40°C to +300°C
Handheld thermometers for resin temperature verification
Discharged resin temperature check
The temperature of the discharged melted resin can be checked. This can lead to quality improvement of the process.
