Abstract:Aiming that traditional artificial data acquisition is not suited for longdistance transmission and intelligent control, a new measurement method was designed.The feasibility of transmitting signals with current was analyzed, and a small,energysaving hydraulic pressure transmitter was devised. The experimental results show that the design is simple, intelligent, suits remote applications and can reduce the worker’s workload. When the sensor is changed, the circuit also suits other occasions.
