Detailed introduction
The YTA series temperature transmitters convert sensor signals into a standardized 4~20mA signal or FOUNDATION™ fieldbus communication signal. Ordinary temperature instruments must use long compensating wires or three-core cables to connect the transmitter in the control room, which usually results in wiring resistance or signal noise. The YTA series eliminates these drawbacks.
Here’s a concise summary of the key features of the Yokogawa YTA110, YTA310, and YTA320 temperature transmitters:
🌡️ Common Features (YTA110/310/320)
Sensor Inputs: Accept RTD, thermocouple, ohm, or DC millivolt signals.
Output Signal: 4–20 mA DC analog output.
Communication Protocol: BRAIN protocol supported (HART and FOUNDATION Fieldbus available on some models).
Mounting: Field-mountable with robust dual-compartment housing.
Ingress Protection: NEMA 4X / IP67 rated for harsh environments.
Safety: SIL 2 certified (BRAIN protocol); TÜV NORD approved.
🔹 YTA110 / YTA310 (Single Input)
Designed for single sensor input.
Ideal for standard temperature measurement applications.
🔸 YTA320 (Dual Input)
Dual sensor input enables:
Failed Sensor Backup
Temperature Averaging
Differential Temperature
