Yokogawa Temperature Transmitter YTA50-A/KS2
The Yokogawa Temperature Transmitter YTA50-A/KS2 is a head mount type of temperature transmitter that accepts thermocouple, RTD, ohm, or DC milivolt input and converts it to a 4 to 20mA DC signal for transmission. The Yokogawa Temperature Transmitter YTA50-A/KS2 conforms to the standard DIN formB head mounting.
