Fluid Property Sensors

Based on patented tuning fork technology for the fluid property measurement of viscosity, density and dielectric constant, and coupled with their efficient software algorithms, the Fluid Property Sensor portfolio of products is specifically designed to provide fluid quality and condition monitoring capability to a wide range of dedicated applications including oils (engine, hydraulic, transmission), fuels and DEF (i.e., urea) monitoring. A robust design enables FPS sensors to operate under diverse pressure, flow and temperature conditions to bring real time fluid monitoring to engines, fuel systems, SCR systems, compressors, transmissions, gear boxes and many other industrial applications.

Our high performance urea quality sensor is also a urea concentration sensor (optimally a DEF sensor) used as an integral part of NOx emission control and compliance strategy when used in conjunction with Selective Catalytic Reduction (SCR) systems. This is an exhaust after treatment method used with diesel engines to reduce NOx emissions. The SCR system relies on the injection of an aqueous urea solution into the exhaust stream in order to facilitate the reduction of NOx emissions.
