Capacitance transducer GM-115
All of the material has the permittivity that is a basic constant.
This product can detect the capacitance by measurement of dielectric constant which all of the material has.
This is the transducer that completely eliminate the problem of conventional capacitive measuring.
This can be measured without being affected by the conductivity change of material.
There is a moisture meter as a typical application example.
Because, since the dielectric constant of water is larger than the other common materials is easy to measure.
This product was developed to work with a more wide range of applications.
Each different dielectric constants, liquid "A" and liquid "B" are mixed, and decide the reference value.
When the mixing ratio of two types liquid is changed, capacitance value will change too.
If you set the reference value, this can capture the change in physical properties like a mixing of foreign matter or a abnormal of mixing ratio. And can monitor in real time.
Feature
●This product can be detected a change of the insulating material or the conductive substance like water.
●Sensor shape and structure can be designed to suit the measurement target substance.
●This product can be measured the capacitance without being affected by the conductivity, So can be measured substances of many types.
●This product can outputs the conductivity and the capacitance at same time, So this has high reliability on monitoring of component change.
