 Detailed description

Yokogawa Temperature Transmitter YTA70-E

The Yokogawa Temperature Transmitter YTA70-E 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 YTA70-E conforms to the standard DIN formB head mounting. The Yokogawa Temperature Transmitter YTA70-E supports HART communication protocol.
