The APM high shear fluid condition sensor platform is a breakthrough in viscosity sensing applications. The APM fluid condition viscosity sensor is solid state with no moving parts and based on a rugged quartz crystal design. The surface of the sensor is also treated to be scratch and chemically resistant. It operates at 160MHz producing a very high shear rate in liquids. The sensor is fully immersible and can be easily configured for insertion into a myriad of processes. Unaffected by flow or vibration conditions, the APM fluid condition viscosity sensor is operable from 0 to 1000cP. It can be operated in fluids at temperatures ranging from -50°C to +145°C and comes with a smart digital interface.
