Crumb Rubber Moisture

Having the correct crumb rubber moisture levels has become a critical component during production. The crumb rubber can easily become either too wet or dry wasting manufacturer’s time and money as well as impacting the quality of the end product.

With the help of industry partners and 40 years of knowledge, MoistTech has developed the IR-3000 crumb rubber moisture sensor that is ideally suited to measure the crumb rubber moisture levels during production.


Install the IR-3000 Crumb Rubber Moisture Sensor several inches above the conveyor, prior to the bailing area. The sensor can continuously monitor the process and can control the crumb rubber moisture content either manually or automatically in the finished product.


If the sensor has to be installed close to dryer outlet where it will be susceptible to extreme heat conditions, it may be necessary to cool the sensor with either air or water.

Furthermore, if the rubber is steamy, it may be necessary to install an air purge system to prevent steam from condensing on the sensor’s window.

Benefits of Crumb Rubber Moisture Control

  • Improved Product Quality
  • Lower Energy Costs
  • Reduced Start-up Times
  • Less Waste
  • 100% Product Inspection
  • Less Downtime

MoistTech is very experienced with the requirements in the production of crumb rubber. Our sensor calibrations, measurement wavelengths, algorithms and sensor optical requirements are pre-set at the factory. Typical accuracy is about ±0.1% moisture. Typical analog range is 0-5% moisture. The outputs can be adjusted to optimize PLC or recording requirements.
