Open the CIPO recordAbstract From the Canadian patent
The present invention is concerned with a moisture sensor for measuring the moisture content of particulate material like ore concentrates. The sensor comprises a body having one end to be buried within the bulk of the particulate material and the other end coupled to a force transducer. The force transducer itself is coupled to display means so that when a conveyor , containing the ore concentrate is in operation a signal is generated from the , force transducer and displayed as a result of the drag force exerted by the particulate material on the body. The moisture content may therefore be determined either by means of a calibration chart or by the output of a , calibration computer.

Why it's free to use
- Filed May 26, 1998 and granted April 22, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 26, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 26, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
