Capacitive Moisture meter






Intrinsically safe construction(i3nG5)


Capacitive moisture meter is designed to measure, in a manufacturing process, the moisture content of the object to be measured, drawing on the capacitive correlation between the object being measured and the moisture content. The detectors have to be installed at either upper side or lower side in the vessel (tank) to contact the object to be measured.


Every material has intrinsic electrical characteristics such as permittivity and conductivity. This transmitter detects electrostatic capacitance changes generated by the rise or fall of the water content of the measured substance in the tank, and then converts these changes into an integrated signal. A variety of meters and electrodes are available according to the measurement condition.

Model QBS-MM
(Non-explosion-proof type)
<Separated transducer type>

This model is composed of detector unit, transducer and special cable.


Model NSB-MM
(Intrinsically safe construction / i3nG5)
<Totally separated detector unit type>

This model is composed of detector unit, transducer, relay power source and special cable that is 4 core control cable. As the transducer is designed to be installed in a dangerous area, the special cable can be made short enough to minimize picked-up noises, thus permitting a stable performance to be obtainable. As to performance, this model has the same characteristics as those of Model QBS-MM.
