The Rish CON-V transducer series measures and converts AC voltages to DC process signals for direct input into monitoring systems such as recorders, data acquisition systems, panel monitoring instruments etc. The CON-V transducers process true RMS signals, providing accurate readings for signals that contain harmonic distortion. The input signal is converted into a load independent signal and the output signal generated is proportional to the mean root square value of the input voltage value.
