The sensor electronics units of DYNAguard V connected with process couplings of ESR series helps to monitor the mass flow in solid material handling applications such as pneumatic transport lines, feeders or gravity chutes in a wide range of mass flow from g/h to t/h.
Conveying or feeding problems of powders, pellets or granules are detected early and thus should be avoided. This helps to prevent plant failures like clogging, material loss, idle or other serious difficulties.
The meter detects moving electrical charges that are produced, for example, through friction with other objects such as the pipe wall and then naturally adhere to the solids surface, solid lining will not be detected.
A multitude of sensor mechanics units makes process coupling very easy and allows cost effective solutions for almost any monitoring application - also in existing conveying systems. The advantage of this modular concept also appears in case of refit or exchange.
The device is not applicable for solids which build up an electrical conducting layer on the sensor through friction or deposition.
