Yokogawa Releases YTA610 Temperature Transmitter

Tokyo, Japan - September 30, 2016

Yokogawa Electric Corporation announces that it will release the YTA610 temperature transmitter on October 3. Although the YTA610 is a mid-range model, it has the same dual-compartment housing for the transmitter terminal block and electronics that is used with the company's high-end models, ensuring excellent environmental resistance.

The release of the YTA610 temperature transmitter completes Yokogawa's revamp of the YTA series, with the YTA610 and the YTA710 (a high-end model that was released in May of this year) succeeding the YTA110, the YTA310, and the YTA320. This revamp of the YTA series product lineup is expected to lead to an increase in sales.


Development Background

Temperature transmitters are used in oil and gas, petrochemical, chemical, electric power, and other types of plants to convert signals from thermocouples, RTDs, and other types of temperature sensors and relay them to the plant monitoring and control system. The YTA series was launched in 1998, and the high reliability and excellent environmental resistance of these transmitters have made them a global top seller.

To begin its revamp of the YTA series, Yokogawa released the YTA710 in May. While featuring the same high environmental resistance and reliability of the other models in the YTA series, this high-end model enables higher measurement accuracy and comes with a number of new functions that meet our customers' latest needs. The YTA610 that is to be released is positioned as the low-priced mid-range model in this product series.

Product Features

  1. Dual-compartment housing
    Many of the mid-range temperature transmitters on the market today cannot be installed in locations where they will be subject to extreme temperatures and high humidity. Although the YTA610 is a mid-range model, it has the same dual-compartment housing found in high-end models such as the YTA710; with the terminal block and electronics in separate compartments, the YTA610 has outstanding environmental resistance.
  2. Choice of the latest digital communication protocols
    The YTA610 supports the latest versions of the HART® and FOUNDATION™ Fieldbus communications protocols, HART 7 and ITK 6. As such, the YTA610 complies with the IEC 61508 standard, which was specified by the International Electrotechnical Commission (IEC) for the functional safety of electrical and electric equipment. Early next year, it is expected that the YTA610 will be certified as meeting the requirements for safety integrity level (SIL) 2, as defined by the IEC.
  3. Improved self-diagnostics and sensor diagnostic functions
    Each of the transmitters in the YTA series comes with a variety of diagnostic functions that can detect problems with the transmitter such as a disconnected sensor. In addition to these functions, the YTA610 features a variety of new prognostic functions that will improve maintenance efficiency by making it possible to predict when calibration and other maintenance procedures will need to be performed.
  4. Local parameter setting
    Software developed especially for the new YTA models is available that facilitates the setting of parameters for transmitters and other field devices. Basic parameter setting can be performed by just pressing buttons on the indicator. As this eliminates the need for a PC, this is especially convenient when working in the field.
