| Side Mounting Arms |
| |
Various side-mounting arms are available which can be used to mount an anemometer, windvane, or temperature/humidity sensor part-way up a mast or pole.
Note: These side-arms are intended for "general meteorology" applications and are generally not suitable for high-precision applications (e.g. wind assessment) we recommend that only our 405 single-mount in conjunction with suitably dimensioned custom side-arms/booms are used in those cases
(refer to
IEA-11 and IEC61400-121 for guidance)
Our new 415 Universal Instrument Side-Arm" replaces the 405E, 405E-L2 and 405-OM (which will only be available until stocks are exhausted).
The type 415 Universal Instrument Side-Arm is designed for mounting T351 series temperature screens & sensors, the type 415 universal side mounting arm is constructed from heavy-gauge silver-coloured epoxy painted stainless steel for maximum resistance to the weather & corrosion.
- The 415 may also be used to mount A100 Series Anemometers and W200 Series Windvanes in general meteorological applications replacing most older 405 series side-arms and 405-1 series dual/cross-arms.
415 Fixing Kits:
A selection of "fixing kits" is available to fit the 415 arm to poles/masts ranging from 1inch (25.4mm) to 12inch (305mm) diameters without requiring specially made "top-fittings" or "adaptors". The arm"s design allows fitting to both round and square section poles, and to the corners of lattice masts, and a pair of arms can be mounted "back-to-back" at the top of a pole to serve as a "cross-arm" to mount a pair of instruments at the top of a mast. Direct wall-mounting is also possible. The 415 can also be used "upside down" to support T302 temp sensors and SW120 wetness sensors.
Available fixing kits are:
/S - to fix to 1in to 2in dia. poles/masts (uses stainless-steel V-bolt)
/M - to fix to 2in to 6in dia. poles/masts (uses 11mm stainless-steel strap)
/L - to fix to 6in to 12in dia. poles/masts (uses 16mm stainless-steel strap)
Note that this 415 arm is NOT suitable for mounting A100/W200 series instruments in wind-assessment applications, or similar applications, where the highest accuracy/performance is required - Please request information on our type 405 pole mounting adaptors in those cases.

OBSOLETE SIDE-ARM MODELS:
Mast-top T351 Mini-Screen Adaptor Arm:
The 405-OM Offset Mount arm is intended for mounting a T351 Temperature Sensor/Screen on to a 405-1 Series Dual Mounting Arm (Cross-Arm) together with an anemometer and windvane. The 405-OM is now obsolete - please use the 415 Universal Instrument Side-Arm above instead.
