The measurement system DYNAguard L is a microwave barrier and consist of a transmitter and a receiver unit. It is used for level monitoring or level detection of bulk material e.g. in silos, pipelines, chutes, containers, feeding- / receiving vessels and hoppers.

Based on the est microwave technology, the transmitter unit lat sends out microwaves which are evaluated by the receiver unit. Bulk material that is conveyed e.g. into a hopper is piling up slowly between transmitter and receiver and attenuates the signal. This initiates a ndividually adjustable switching operation which indicates that a certain level in the hopper is reached. Conversely the system can be used for minimum level detection also when silos are emptied.

The DYNAguard L can also measure through electrical insulators. In case of special process conditions (temperature, pressure, specific products) this allows also to disconnect the system from the vessel to be monitored.
