Bench for temperature fatigue of pressure transducers

The bench is equipped with four electrically heated and liquid-cooled (DURATHERM-S oil) screeds by means of a circuit equipped with a circulation pump and a shell and tube heat exchanger, to be connected to the central cooling system (air cooling is not necessary).
The pressure generation circuit consists of three high-pressure pumps, one for each of the three working ranges. Each pump is equipped with a valve and a reference transducer.
