The Micro Liquid Density Sensor (LDS) can measure BRIX, °Plato, specific gravity, concentration, temperature and density. The LDS can directly measure fluid viscosity in addition to density and temperature. Viscosity measurement combined with density and temperature measurement can be indicator of material composition or quality. For instance in ink jetting viscosity is an indicator of the quality of ink similarly with motor oils the viscosity relates to the quality of the oil. This sensor has an option for Modbus communication as well.
The Micro Sensors are available in two different versions: the Micro Liquid Density Sensors (LDS) and the Methanol Concentration Sensor (MCS). These sensors are designed to integrate and embed into larger systems and solutions to satisfy the needs of system integrators and OEMs. Currently the Micro Sensors can measure density for liquid materials only.
The principal of operation is based on the Coriolis effect however, the resonating sensing tube takes advantage of MEMS technology. These devices have MEMS inside. The result is a very accurate density measurement for performance in a very small package. These sensors are designed for use in general purpose electrical environments. The sensors are calibrated to cover a range of 0.6 to 1.3 grams/cc. Voltage outputs are used to communicate measured density and temperature. A RS-232 serial output is also available.
