Attenuators - Import export

The CoMeT system is used to measure the screening effectiveness (transfer impedance, screening attenuation and coupling attenuation) of coaxial and symmetrical cables, connectors, bushings, distribution components, etc. The original CoMeT (Coupling Measuring Tube) has grown into a complete system. In principle, a cable measuring station consists of the following basic components: In addition to differently dimensioned round tube systems for cables and connectors, there are also so-called “triaxial cells” that provide a larger measuring chamber volume for parts that do not fit into one of the tubes due to their geometry (sockets, distributors, etc.).

Glass Neutral Density filters attenuate light by absorption just like the gelatine neutral density filters. Glass ND Filters are more robust and tend to have more uniform absorption characteristics. They also attenuate by absorption and so care must be taken to avoid overheating. Attenuation is achieved by polishing glass to the correct thickness. Knight Optical offers stock absorptive ND filters in 12.5mm and 25mm diameters, and 50x50mm squares manufactured from high quality glass. Each filter is available with blocking between 0.1 and 4.0 OD and are available to purchase direct from this page. In addition to our stock absorptive glass ND filters, Knight Optical also offers an extensive custom optic service thanks to our many years of experience in the industry. We can supply ND filters cut to sizes and shapes to fit individual application and mount filters where applicable. READ PDF FOR FULL SPECIFICATION

What you can expect from APROVIS silencers: - Standard versions for selected engines - Individual design and construction for every application - Assured sound reduction even with high requirements - Cost- and installation space-optimised design that makes use of the pressure drop

The SLC and SRC rectangular duct silencers reduce the noise level in ventilation and A/C systems. This silencer type is usually installed between a fan and an air supply or exhaust duct, and upstream of air supply vents. All silencers are made of a housing and inner baffles. The housing is made from galvanized steel sheet and its ends are framed with steel sheet angles. All baffles inside the silencer have a round breast at one end and comprise a galvanized steel frame with a soundinsulating insert which absorbs the acoustic energy from the air flow. The soundinsulating insert is a set of nonflammable mineral wool panels. The outer surface of the soundinsulating insert is lined with a special abrasionresistant textile to protect the mineral wool from wear and tear. The mineral wool panels are finished with a glass fibre lining in black; this lining is suitable for systems with a maximum air flow rate of 20 m/s.

- Attenuation value changes along with temperature. - Wide frequency and better characteristic. - Small SMT type (2.0mm×1.2mm) - Realization of temperature characteristic by adjustment of thermistor characteristic.
