Yokogawa YTA50 Temperature Transmitter

The Yokogawa YTA50 is a head-mount temperature transmitter designed for precision and long-term stability. Accepting thermocouple, RTD, ohm, and DC millivolt inputs, this device delivers a 4 to 20 mA DC analog output proportional to measured temperature. Built for industrial environments and hazardous area installations, the YTA50 series remains a dependable choice worldwide.

This article covers complete technical specifications and provides a full model breakdown for YTA50-A/KS2 — a regular offering from ST-YUKE CO., LIMITED.

Overview

The Yokogawa YTA50 operates as a 2-wire analog temperature transmitter with microprocessor‑based sensing for high accuracy and signal integrity. It conforms to DIN Form B head mounting standards, making installation straightforward in most connection heads. Additionally, it supports both head mount and DIN rail mount configurations depending on application needs-24.

Thanks to its wide input selection and minimal straight‑pipe requirements, the Yokogawa YTA50 series fits diverse process environments requiring consistent, noise‑resistant temperature transmission.
