SensoTech Presents LiquiSonic® Lab 3-in-1 Sensor for High Precision Process Monitoring SensoTech GmbH has designed a high precision 3-in 1 sensor for laboratories and technical centres.
T
o provide a functional solution to inline reaction monitoring, where little space is available, and under harsh conditions, SensoTech has developed a 3-in-1
sensor designed for reactors and small plants in laboratory and technology centres, which enables high precision monitoring of sonic velocity, attenuation and temperature.
LiquiSonic® System: Controller and a model of a sensor with 12 mm diameter, typically installed in the lid of laboratory reactors of pressurized vessels.
LiquiSonic® is directly flanged into the reactor lid and provides an opportunity for complex polymerization or crystallization reactions monitoring, e.g. in down-scale reactors, and even in harsh conditions like high temperature or pressure.
