Hycontrol Guided Wave Radar TDR Reflex VF4 Liquids&Solids

Guided Wave Radar TDR Reflex VF4 Liquids&Solids


Manufacturer: Hycontrol

Hycontrol's new Reflex VF04 TDR measuring probe measures liquids and solids up to a maximum range of 24m with an accuracy of +/- 5 mm, making it an ideal choice for a wide variety of applications. The unit is unaffected by pressure, temperature, viscosity, vacuum, foam, dust, coating or changes in dielectric constant, and offers a selection of durable and highly reliable probes.

A key feature of the new VF04 TDR unit is the VGF-DISPLAY removable programming unit, which connects to the top of the instrument head and allows programming via touch buttons and an LCD screen. This allows for fast programming and simple commissioning, with the display unit able to be removed for safe-keeping afterwards.

The TDR principle of operation is a simple one: pulses of low power microwaves are sent along conductors. At the point where the wave meets the product surface, it is reflected by the product. To provide level information, the instrument measures the time between emission and reception which is proportional to the distance.

VF04 is a cost-effective, practical solution to a wide range of level monitoring and control applications, and as a result is highly recommended by Hycontrol engineers.
