Measurement Specialties, a manufacturer of sensors and sensor- based systems, has acquired the assets of California- based Visyx Technologies. The terms of the transaction were not disclosed. Based on a tuning fork technology originally developed by Symyx Technologies, Visyx has developed sensors that can measure fluid properties, including density, viscosity and dielectric constant. This technology will allow OEMs to incorporate fluid property measurement, such as oil condition, in their next generation equipment. Target markets include heavy truck/off road engines and transmissions, compressors/turbines and refrigeration/air conditioning.
