Our Technology

Real-Time Moisture Measurement Technology

Bry-Air PROKON Moisture measurement technique is based upon the relatively high dielectric permittivity (commonly called DIELECTRIC CONSTANT) of water (80-35) in comparison to the dielectric properties of the polymers (2-5).

The variation of water content within the product, would result in a variation in the combined dielectric constant which would then be measured by monitoring the changes in the dielectric signal. The technology used, provides the ability of the sensor to separate real (capacitive) and imaginary (conductive) components of dielectric permittivity.A calibration against a known moisture amount is required.

This extra, offers the speed of obtaining a moisture measurement (seconds instead of minutes), and allows a quick fix of the production process. All our systems do not require any specific knowledge of physics/chemistry of materials to control.

How It Works

01

The H2O molecule constitues an electric dipole.

02

Polar molecules will generally be in random orientations when no electric field is applied.
An applied electric field wil polarize the sensor by orienting the water dipole.

03

A special PTFE insulator is used to maximize the stability of the reference capacitance.
The sensor is equipped with a special TC sensor which allows the software to adjust the measure at whole range of measure.
Temperature, mechanical adjustment, aging, enviornments can affect the repeatibility of the sensor: our sensor has an automatic ZERO routine, performed automatically anytime sensor is empty.
