DYNA - Model DYNAguard L -Microwave Level Detection for Bulk Solids
The DYNAguard L is a sophisticated microwave barrier measurement system consisting of a transmitter and receiver unit designed specifically for the level monitoring and detection of bulk materials. This system operates by emitting microwaves from the transmitter, which are then received and evaluated by the receiver unit. As bulk material accumulates between the transmitter and receiver, it attenuates the microwave signal, triggering individually adjustable switching operations to indicate that a certain level has been reached. Conversely, it can be used for minimum level detection when silos are being emptied. This versatile system supports contactless measurements and features an LED display for easy individual adjustments. It is especially suitable for use in silos, pipelines, chutes, containers, and various vessels. Furthermore, it can measure through electrical insulators, which is beneficial in special process conditions involving temperature, pressure, or specific products, thereby allowing the system to be disconnected from the vessel being monitored. The DYNAguard L offers reliability and ease of installation, even in GRP containers.-

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.
