Product Description
The Yokogawa YTA70 JA12 is a state - of - the - art temperature transmitter module designed to convert temperature sensor signals into standardized output signals. Yokogawa, a renowned Japanese company with a long - standing reputation in the field of industrial automation and measurement, has engineered this module with precision and innovation.
Thermocouples: The YTA70 JA12 supports a wide variety of thermocouple types, including JIS, IEC, and DIN standards such as R, S, B, K, E, J, T, and N. This versatility allows it to be used in different industrial environments where specific thermocouple sensors are already in place. For example, in a power plant where K - type thermocouples are commonly used to measure high - temperature steam, the YTA70 JA12 can seamlessly interface with these sensors.
Resistance Temperature Detectors (RTDs): It is compatible with 2 - wire, 3 - wire, and 4 - wire RTDs. Common RTD types like IEC Pt100, Pt200, Pt500, and JIS Pt100 can be connected. In a pharmaceutical manufacturing process where accurate temperature control in a reaction vessel is crucial, an IEC Pt100 RTD connected to the YTA70 JA12 can provide highly precise temperature data.
Other Inputs: The module also accepts DC mV signals and resistance values in the range of 0 - 2000 ohms. This flexibility makes it suitable for custom - made temperature sensors or applications where non - standard temperature - sensing elements are used.
Features
The YTA70 JA12 features a two - wire 4 - 20mA DC output. This is a widely adopted standard in industrial automation, as it allows for easy integration with other control systems such as Programmable Logic Controllers (PLCs), Distributed Control Systems (DCSs), and Supervisory Control and Data Acquisition (SCADA) systems. The 4 - 20mA signal can be easily transmitted over long distances with minimal signal degradation, making it ideal for large - scale industrial plants.
HART Communication: The YTA70 JA12 supports the HART (Highway Addressable Remote Transducer) communication protocol. This protocol enables two - way digital communication between the transmitter and a host system. With HART, users can remotely configure the transmitter, access diagnostic information, and monitor the temperature readings more accurately. For instance, in a petrochemical refinery, maintenance engineers can use a HART - compatible handheld device to quickly check the status of multiple YTA70 JA12 transmitters located in different areas of the plant without the need for physical access to each device.
Industrial Process Control
- The module requires a power supply in the range of 7 - 35V DC (7 - 28V DC for intrinsically safe models). This wide power supply range allows for easy integration into different power systems within industrial plants. In a small - scale industrial unit with a 24V DC power supply or a large - scale factory with a variable power supply infrastructure, the YTA70 JA12 can be powered without the need for complex power conversion systems.
High Precision: The module offers an impressive accuracy. For thermocouple inputs, the accuracy is typically ±0.1% of the span or ±1.0°C (whichever is greater for some types), and for RTD inputs, it is ±0.1% of the span or ±0.1°C. This high level of accuracy ensures that the temperature measurements are reliable, which is crucial in applications where even small temperature variations can have significant impacts. In a semiconductor manufacturing cleanroom, where precise temperature control is essential for the production of high - quality chips, the accuracy of the YTA70 JA12 helps maintain the optimal process conditions.
Cold - End Compensation: For thermocouple inputs, the YTA70 JA12 provides accurate cold - end compensation with an accuracy of ±1°C (±1.8°F). This is important as thermocouple measurements are affected by the temperature at the reference (cold) junction. The accurate cold - end compensation feature ensures that the measured temperature values are correct, regardless of the ambient temperature around the thermocouple connection.
Temperature Range: The YTA70 JA12 can operate in a wide environmental temperature range of - 40°C to 85°C (- 40°F to 185°F). This makes it suitable for use in various harsh industrial environments, from cold storage facilities to high - temperature industrial furnaces. In an Arctic oil drilling platform, where the ambient temperature can drop well below - 40°C, the YTA70 JA12 can continue to function reliably, providing accurate temperature measurements for the drilling equipment.
Humidity Resistance: It can withstand humidity levels ranging from 5% to 90%RH at 40°C (104°F). This resistance to humidity is crucial in industries such as food and beverage, where high humidity environments are common. In a brewery, for example, the YTA70 JA12 can be used to monitor the temperature of fermentation tanks without being affected by the high humidity in the production area.
