 A Closer Look at Each Benefit

1: Built to last

Durability assured even in the harshest industrial environments

Dual compartment housing

The Yokogawa advantage

  • Dual-compartment housing isolates and protects the internal electronics from corrosion
  • Heavy-duty NEMA 4X, IP67 enclosure

The benefits to you

  • "Install and forget" durability in the most demanding applications
  • Mean time between failures (MTBF) of 172 years
    (1/λ)A 172 year MTBF means that if you purchased 172 YTAs, you may experience one failure within the first year of operation.

TÜV NORD certificate

2: Safety first

SIL2 certified right out of the box - At Yokogawa, safety is not an option

The YTA advantage

  • Superior hardware design
  • Back calculation function for improved verification of sensor readings

The benefits to you

  • A higher level of safety: YTA 110, 310, and 320 temperature transmitters are TÜV certified for SIL2 applications.
  • No additional investment in optional hardware or specialized software necessary

3: Designed for the field

Optimized for ease and versatility

Designed for the field

The Yokogawa advantage

  • Information-rich graphic and numeric displays
  • Two-level connection terminals
  • Universal input accepts thermocouple, RTD, ohm and DC millivolt sensor inputs.

The benefits to you

  • All essential information is clearly displayed: You can confirm key parameters in the field without a handheld terminal.
  • Easier routing of wires for termination
  • Reduced inventory costs

4: High accuracy and reliability

Results that you can count on

The YTA advantage

  • Sensor matching function corrects for differences in individual temperature sensors.
  • Dual input sensor and data averaging are also available in the YTA320.

The benefits to you

  • High performance D/A converter delivers an accuracy of 0.02% of span.
  • Up to a 75% reduction in total measurement error
  • Sensor backup / redundancy with the YTA320 for even greater reliability

5: Excellent long-term stability

Stays steady and true

The YTA advantage

  • Reference voltage cancellation function corrects for changes in ambient temperature, maintaining long-term stability.

The benefits to you

  • Industry-leading 5 year stability
    RTD: ±0.2% of reading or ±0.2˚C, whichever is greater at 23±2˚C
    T/C: 0.4% of reading or ±0.4˚C, whichever is greater at 23±2˚C
  • No need for frequent calibration

YTA50

The YTA50 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 YTA50 conforms to the standard DIN formB head mounting.

YTA70

The YTA70 is a head mount type of temperature transmitter that accepts thermocouple, RTD, ohm, or DC milivolt input and outputs a 4 to 20mA DC signal with HART digital communication.

YTA110

The YTA110 is the high performance temperature transmitter that accepts thermocouple, RTD, ohm, or DC millivolt input and converts it to a 4 to 20mA DC signal for transmission. The YTA110 supports either BRAIN or HART communication protocol.

YTA310/YTA320

The YTA310 and YTA320 are the highly accurate temperature transmitters that accept thermocouple, RTD, ohm, or DC milivolt input(s) and convert it to a 4 to 20 mA DC signal for transmission.

The YTA310 is a single sensor input model, and the YTA320 is a dual input model. Both models support either BRAIN or HART communication protocol, and YTA320 also supports FOUNDATION™ fieldbus.
