Relative permittivity of a liquids
Description
The relative-permittivity meter is designed to measure, in a manufacturing process, the relative permittivity of a liquid by mounting a detector on the bottom of a mixing tank.
Continuous measurement of relative permittivity for constant determination of the mixture ratio and pass/fail determination of the extent of mixing helps manufacturers to improve product quality, production efficiency and stability.

Configuration
Model QBS-RP
(Non-explosion-proof type)
＜Separated transducer type＞
This model is composed of detector unit, transducer and special cable.
Configuration
Model NSB-RP
(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-RP.
