Conductivity sensing ensures rubber product quality.


Conductivity conductivity /con·duc·tiv·i·ty/ (kon?duk-tiv´i-te) the capacity of a body to transmit a flow of electricity or heat; the conductance per unit area of the body.

 sensing technology is now used by Calzin, an international supplier of coatings for the rubber industry, as part of a measurement system that helps ensure customers get consistent product quality, as well as reducing their labor and materials labor and materials (time and materials) n. what some builders or repair people contract to provide and be paid for, rather than a fixed price or a percentage of the costs.  costs.

Without a properly mixed antitack additive, rubber production can be a sticky situation. Too little calcium stearate Noun 1. calcium stearate - an insoluble calcium salt of stearic acid and palmitic acid; it is formed when soap is mixed with water that contains calcium ions and is the scum produced in regions of hard water

 each other. Too much calcium stearate and sheets could slide off of pallets and end up in the scrap pile.

The system consists of a conductivity analyzer with a tailored custom curve set and electrodeless conductivity sensor. The sensor measures the conductivity and sends a reading to the analyzer. From there, the software triggers alarms when conductivity setpoints are reached, which control a series of valves and pumps that supply the Calzin concentrate and water in proportions to maintain a predetermined pre·de·ter·mine
