General Description

The SAIT Trainer is designed to show most of the devices used in the industry that allow the electronic systems to communicate with the real world, to measure physical variables and to control industrial processes.

It is a trainer with a logical distribution of its components that facilitates the rapid comprehension of the elements that form it, all housed in a solid robust with the power supply incorporated.

Input Transducers:

These convert an analog signal into an electrical one and permit us to make an evaluation of these transducers, with their characteristics, adjustments and practical applications.

Output Transducers:

These convert an electrical signal into an analog one permit us to make an evaluation of these transducers, their characteristics, adjustments and practical applications.

Signal Conditioning Circuits:

These allow us to carry out a profound study and analysis of the numerous circuits and included signal conditioners, in addition to the particular properties of: amplifiers, signal converter circuits, comparators, filters and circuits that carry out mathematical operations. The student must wire the circuit to carry out the practices. The connections are of 2 mm. The student will become familiar with the connections of these traducers .
