Emerson's industry-leading Rosemount Temperature Transmitters are meticulously engineered to deliver superior performance, enabling the acquisition of accurate and reliable measurements even in the most demanding application environments. With a diverse range of housing styles available, you can select the optimal option to align with your specific application requirements. Additionally, leveraging the Advanced Diagnostics functionality provides valuable insights into your process, facilitating safer and more efficient operational outcomes. 

YOKOGAWA  It delivers high accuracy, stability, and reliability. The housing structure features a robust dual-compartment design. For sensor input, users can choose between single or dual inputs, which are compatible with RTDs, thermocouples, ohms, or DC millivolts. It converts the sensor input into either a 4 to 20mA DC analog signal or a Fieldbus digital signal. Available communication protocols include HART 7 Protocol, BRAIN Protocol, and FOUNDATION™ Fieldbus ITK 6 version. The dual-input configuration supports functions such as calculating differential or average values from two sensors, as well as a sensor backup feature. This backup function enables automatic switching from the primary sensor to the backup sensor in the event of a primary sensor failure. 

Thanks to the integration of a local parameter switch on the indicator, on-site setting and configuration work becomes simplified and convenient.

• Advanced diagnosis

The Yokogawa YTA710 utilizes the IEC60751 standard to define the resistance-temperature relationship for RTD sensors, a relationship known as the Standard Curve. While sensor manufacturers adhere to this same standard, each sensor develops a unique temperature-resistance relationship—referred to as the Real RTD Curve—due to variations in the manufacturing process. (Notably, the Real RTD Curve remains within the tolerance range specified by the IEC60751 standard.)  

In the 1920s, Hugh Longbourne Callendar and M.S. Van Dusen developed a set of coefficients designed to modify the Standard Curve, enabling it to align with the Real RTD Curve. This adjustment effectively eliminates the error caused by discrepancies between the two curves. Equipped with the CM1 option, Yokogawa's YTA710 can accept these coefficients to calibrate the Standard Curve, ensuring it matches the sensor’s specific Real RTD Curve. By eliminating this source of error, the overall accuracy of the YTA710/sensor system is significantly enhanced.
