The Yokogawa UP750-51 is a highly versatile Programmable Digital Panel Meter designed for precise display and processing of a wide range of industrial signals.
Its core function is to accept an input signal from a sensor or transmitter, perform scaling, linearization, and other calculations, and then present the measured value on a large, easy-to-read display. The "51" in the model number is a key identifier that typically signifies it is pre-configured or particularly suited for a specific input type, most commonly AC Current when used with an external Current Transformer (CT).
