INZOC
The IFV-3 / IFV-4 / IFV-5 series sensors adopt patented multi-functional integrated detection technology combined with the FOS oil data model and industry-leading backend data processing modules. This architecture forms a wide-range, high-precision, multi-function oil condition monitoring sensor, significantly reducing repeated drilling and complex installation challenges commonly encountered in online oil monitoring applications. The sensor integrates: Dynamic viscosity; Density; Dielectric constant (oil quality); Water content; Temperature. All parameters can be measured simultaneously, with additional indicators available as optional configurations.
