moreover, layers of different alloys, which, during the production process, are firmly welded to each other over the entire contact area. All alloys used, which contain a thermobimetallic strip, must differ significantly in temperature coefficients of linear expansion. A component with a large TCLE is called active, and a component with a low TCLE is called passive.
Bimetallic tape can have an intermediate layer of nickel or copper, which has significant electrical conductivity. Drawing on both parties of a strip of an anticorrosive layer from a stainless steel is possible.
The main product properties are determined by:
– Thermal sensitivity.
– Electrical resistance.
– The temperature span of the service.
It is possible to change the thermal sensitivity and resistance by combining alloys in an active and passive layer, the ratio of their thicknesses, by introducing an intermediate layer.
You can buy thermometallic tape for the production of temperature sensors, thermal relays, relay circuit breakers, switching equipment, thermal compensation systems , control devices.
