Holder for 1/2″ preamplifiers. Holds the preamplifier in upright position.
Typical use is in calibration laboratories when calibrating microphones.
Steady tripod with extension rod for microphone preamplifier.
Can be delivered with mounting accessories for all hand held Norsonic Sound Level Meters.
Picture shows the Nor121 version.
Microphone tripod for standard 1/2” or 1/4” microphones and preamplifiers.
Maximum height of the tripod is 3,66 m. An additional rod of 1.1m following with the kit mounted onto the tripod by a pivoting clamp enables the user to point the microphone in any position. Pointed upwards the complete assembly is 5m.
The thread on the centre column is 3/8″. The 1.1m rod has both 1/4″ and 3/8″ threads. Fits with our outdoor microphone kits.
The pivot clamp and the microphone rod are not shown in this picture. It may be seen on the picture for microphone tripod Nor1307.
The Nor1329 is a microphone mast for permanent installation of noise monitoring systems based on Nor1501 double walled enclosure and Nor1210 All-Weather Microphone or Nor1212 microphone protection kit.
It may be tilted to provide easy calibration and service of the microphone unit and the weather station (if applicable). The microphone cable and the cable for the optional weather station are both mounted inside the mast to minimise wind-induced noise and to protect the cables from sun and heavy weather conditions. The mains cable may also be mounted inside the mast. A lid in the base unit of the mast ensures easy access to mains cable and the connection of it.
The microphone is electrically insulated from the mast in order to minimise electrical induced noise.
The mast is made of steel and is coated in a seven-step process in which zinc phosphate and powder are melted onto the hot-dip galvanised steel at a carefully controlled temperature. This ensures a top finish and durability against corrosion even in rough environments. The mast has been widely used for years in permanent noise monitoring systems installed all over the world, showing no effects of aging and corrosion.
Special lengths available
The mast can be delivered in any length up to 9 metres. Standard length is 5.5 metres.
Foundations and brackets
The mast should be mounted onto a concrete foundation or on a special steel foundation.
The steel foundation Nor1329/02 is fast and easy to mount and is a well-proven technology widely used on lightning columns.
A special anchor frame Nor1329/03 should be used if a concrete foundation is used. The anchoring frame is simply pushed into the wet concrete. This enables a fast and accurate mounting of the microphone mast onto a concrete foundation.
A special bracket, Nor1329/01 may be attached to the mast to allow mounting of a weather station.
Bracket for mounting a weather station onto the microphone mast Nor1329.
The Brackets is in its standard version prepared for the Reinhardt weather station type MWS-9 or MWS-5 series.
The bracket is hot dip galvanized only and cannot be delivered with the additional powder coating as on the microphone mast Nor1329.
The foundation is supplied with a Combi-coat finish and has replaceable bolts. The cable lead-in is protected by a plastic collar. The flange-plate of the lighting column will cover the top of the foundation. This foundation has a number of advantages over other foundations:
- it is very light compared to concrete foundations and can be set in the ground by hand (reducing labour costs)
- its light weight reduces transport costs
- it demands little storage space, as groups of them can be stacked
- it requires less precision in placement, as adjustments to the position of the lighting column can easily be made with it installed on the foundation
- lighting columns placed in ground subject to subsidence can be straightened by adjusting the nuts above and below the flange-plate, thus saving the high costs of digging them up.
Material quality: S235JRG2. The microphone mast Nor1329 normally uses the foundation with a C-C of 160mm (See table below). Special version of the mast may use other measures for the C-C(RSt 37-2).
