YOKOGAWA YTA110 Temperature Transmitter
YOKOGAWA YTA Series temperature transmitters convert the sensor signals to a unified signal, 4 to 20mA signal or FOUNDATION™ fieldbus. This eliminates the drawbacks of wire resistance and signal noise that are often experienced with conventional temperature instruments, which must be connected by long extension lead wires or three-conductor cables to converters in an instrument panel room.
An additional feature is that both the sensor type and the measurement range can be selected.
