Temperature sensors for the rubber and plastics industry are designed for the specific temperature measurement needs of processing rubber and plastic mixtures. The quality of the raw materials, which are then processed, is important. Temperature probes are very resistant to the influence of abrasion from rubber and plastic mixtures and to vibrations.


Sensitive probes in the applications of rubber and plastic manufacturing processes

Unvulcanized rubber and a mixture of this material behave as a viscoelastic liquid during processing. A variety of additives, chemicals, and fillers are added to the rubber during the mixing process. This process creates an unvulcanized rubber mix. The dispersion depends mainly on the temperature.
 

Mixing is carried out on various devices. Proper mixing of the components in the mixture, the shortest mixing time and accurate temperature detection during mixing - these are very important requirements for a quality rubber mixture for production.
 

GUILCOR temperature probes are one of those difficult applications. Our temperature sensors allow us to adapt to the requirements of individual devices from different manufacturers.
 

These special temperature probes have been developed since 2007, year of the design of the TR153-Pt100 probe. The TR 153 temperature sensors meet the mechanical criteria as well as the criteria of accuracy and rate of measurement.

Conflicting requirements for temperature sensors

  • short response time

  • high resistance to mechanical stress

  • high resistance to the influence of abrasion of rubber and plastic mixtures

  • high resistance to vibration and shock



Common characteristics of temperature sensors

  • measuring range -30 to 200 ° C

  • housing material: stainless steel, stainless steel hardenable at the measuring point

  • Pt 100/3850 type sensor, 4 wires

  • the sensor is available in two versions:

- version A - the sensor is fitted with a LEMO connector and can be completed with a metal connection head.
- version B - the sensor is fitted with a ceramic terminal block placed in the connection head.

  • response time - indicative

- According to EN 60 751: τ0,9 ≤ 10s
- Continental method: τ0,9 ≤ 70s

  • From 0 ° C (drift ice) to 180 ° C (flowing silicon oil 0,4 ms-1)
