Taut suspensions BrOF
Taut suspensions measuring instruments BrOF (Taut suspensions, Rubans de suspension, Spannbander)
Taut suspensions BrOF used for mounting the movable part of instrumentation.
Used as streamers (suspenders) to ammeters, voltmeters, wattmeters, varmeters, frequency, phase meter, webermeters, teslameters, testers, combined instrument panel-mounted heads and other precision measuring instruments.
Product specifications are extensions (suspenders) for measuring instruments BrOF:
Material stretching BrOF - tin-phosphor bronze.
The following sizes of stretch marks:
Optimum tension on one stretch - 20 G, 25 G, 27 G, 30 G, 32 G, 50 G, 70 G, 75 G, 100 G or more according to specifications.
Moment at length stretching 100 mm - according to specifications.
Depending on the use made of different sizes - length 33 mm, 50 mm, 70 mm, 100 mm, 120 mm, 140 mm or another according to specifications.
Streamers of tin-phosphor bronze wire is made of in accordance with the requirements of this standard technological regulations, approved in a prescribed order.
Ovality wire taut suspensions BrOF products should not exceed the limit deviation. On-demand e-businesses and watch industry wire made with oval, not exceeding one half of the diameter deviation limit.
Wire surface must be clean and smooth, without cracks.
Not allowed surface hymen, risks, sinks, bubbles, dents depth exceeding (after stripping control) tolerances on diameter.
Allowed on the surface of the wire product taut suspensions BrOF redness, darkening, discoloration and surface damage, not going beyond the wire and the reference sweep for tolerances on diameter.
Fixing the moving part on extensions allows you to perform sensitive devices with a small counter-torque.
In addition, extensions create counteracting moment arising when turning box, and serve to supply current to the frame.
High sensitivity of products obtained by taut suspensions BrOF small opposing points and the absence of friction in the bearings.
Suspension BrOF has high corrosion resistance, good electrical conductivity, they are non-magnetic and elastic properties remain in the process of exploitation and temperature changes.
Recommended soldering stretching produce low-melting solder (Sn - 50%; Pb - 32%; Ca - 18%) with an acid-free flux (rosin fluxing lacquer LTI number 2).
Soldering temperature - not above 150 ° C.
Not allowed joke stretching and wicking of solder on the working part of the stretch:
Solder joints should be thoroughly washed with ether.
Stretching should be soldered to the holder at an angle.
Stretch marks are performed both external and internal.
The manufacturer guarantees the quality of products taut suspensions measuring instruments BrOFtechnical requirements specifications subject to the consumer the terms and conditions of storage, transportation, installation, operation, set specifications and operational documentation.
Stretch marks are produced according to the following standards:
GOST 5.233-69, TU25-04-3227-77, OCT 25, 1196-85.
If you need a streamer (suspension) of tin-phosphor bronze to a voltmeter E365, E350, E545, D5082, ammeter M903, M906, C33, E539, D5080, wattmeter D365, D5016, D345 varmeters, frequency E361, C300, D362 phasemeter, webermeters M1119, F4356 teslameters or other measuring devices, please contact the sales Zapadpribor.
