Temperature transmitters are used in oil and gas, petrochemical, chemicals, iron and steel, pulp and paper, electric power, water treatment 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 has 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 a cost-effective mid-range model in this product series.
1. Dual-compartment housing
The dual-compartment housing of the YTA610 sets it apart from many of its competitors in the mid-range temperature transmitter market by allowing it to 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 FOUNDATIONTM 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.
