Bimetal is a composite material, made of 2
layers, having different expansion coefficients.
A temperature variation makes a distortion,
due to the interaction of these 2 layers which
partially act in opposition.
In snap action applications, the three dimensions (Length/width/thickness) must satisfy specific proportions: this is Delta Concept know-how.
There are about 30 different grades of thermo-bimetal: each of these grades has specific characteristics, as the deflection rate , the electrical resistivity, the thermal resistivity, the density, the elasticity, etc ...
Double function :
A Bimetal (or a bimetal sub-assembly)
is used both as thermo-sensor and as an actuator of a security or a regulation mechanism.
Cost saving and ecological :
The bimetal mechanism is often
designed simple and at low cost.
It is autonomous and it operates without
electrical energy.
Reliable and sustainable :
Our fabrication process guaranties
a reliable operation,
on millions of cycles.
The carrier developed with Global Health Lab, has been approved by the WHO ...
DELTA CONCEPT develops sub-assemblies, using the bimetal technology, in order to have all these functions automatic and energy free
Air distribution lines are made of different mechanical parts, including elements with flaps, for air or smoke flow regulation, as well as for security reasons
