7、Silver alloy/copper/and iron three compound contacts
Silver alloy/copper/and iron three compound contacts
These new products recommended in 2001 can be widely used in
temperature controllers. As contacting material, they have
following features:
1, Face of this compound contacts are of iron with protruding
points so as to reinforce the welding, say, make electrical
contacts weld well with double metal slice and iron alloy. In
common contacts, there are always shortcomings that silver and
copper in them not welded well with iron base metal slice.
2,As far as the contacts of double kinds of metal are concerned,
they will be out of shape it riveted tightly, while they will bring
about increased resistance if riveted loosely. All these lead to
the error in temperature controller.
3, In developed countries, three compound contacts have been widely
accepted, Part of temperature controller manufacturers imported
them from U. S. A., Japan for production. Thus it is likely that
three compound contacts will replace the rivet contacts.
4, In accordance with the current through the temperature
controller, different silver alloy contacts can be chosen, for
instance, AgNi (0.15), Agcdo, AgNi (10).
