RY series transmitters are used to provide linear D. C. Output signals after measuring A. C. Current and voltage. They can be used as analogue acquisition input equipment necessary for RTU (remote terminal unit), computer monitoring and automatic control system, and wildly applied in electricity system and other industrial areas.

According to usage, RY series transmitters can be divided into A. C. Current transmitter, voltage transmitter, active and reactive power transmitter, combined transmitter, electric power transmitter, power factor and phase angle transmitter, frequency transmitter and D. C. Transmitter etc.
