TEMPERATURE TRANSMITTER YT 200 YOKOGAWA

The YT200 is a two-wire temperature transmitter that accepts an input from a thermocouple, resistance thermometer detector or DC voltage ( mV) and converts it to a 4 to 20 mA uniform signal for transmis- sion. The intelligent YT200 supports a broad choice of input signals. When combined with the HART communica- tor, it permits programming input signals, spans, and parameters through two-way communication.
