Transducer or industrial converters are used to convert different analog quantities and temperature to standard voltage signals and flow as well as used for isolation. Existence of isolator amplifier in circuits of such equipments, can prevent the effect of noise on the supply voltage or signal is output.
In general, the transducer can be categorized as follows:
• voltage / electrical Current converter(exchanger) (AC or DC) to voltage / current
• temperature sensor converter(exchanger) (thermocouple or RTD) to voltage / current
• voltage and current isolator
Some of the transducers output are selectable or programmable. The user may then can adjust and calibrate all parameters by a software .
