Adapt the signal output of the sensor to the requirements of the specific industrial system. Generally ( ).

Question

The basic conversion circuit of the sensor is to convert the easy-to-measure small signal generated by the sensitive element to make the signal output of the sensor meet the requirements of the specific industrial system. Generally ( ).

A. 4～20mA、–5～5V

B. 0～20mA、0～5V

C. -20mA～20mA、–5～5V

D. -20mA～20mA、0～5V

Answer 1

The correct answer is: A. 4～20mA、–5～5V.

Analysis: The general sensor is to convert the easy-to-measure small signal generated by the sensitive element, so that the signal output of the sensor meets the requirements of the specific industrial system, 4~20mA, –5~5V is a common standard signal, so the answer is A.
