Field - Mount temperature transmitter for temperature , thermometer instrument
Quick Detail:
The YTA310 is a high performance field-mount temperature transmitter that accepts a single sensor input. This input can be from a RTD, thermocouple, ohm, or DC millivolt. It converts the sensor input to a 4 to 20mA DC analog signal. The YTA110 supports either BRAIN or HART® 5 digital communication protocol. The YTA310 is the choice for control and safety applications.
YTA310 features include:
§ Dual-compartment field-mount housing
§ TUV Nord SIL 2 Certified
§ Sensor Matching (available)
Description:
Rugged Construction
Robust dual compartment housing with hermetically sealed terminals protects the electronics from moisture ingress and eliminates the need to expose the electronics to the environment. This ensures a long service lifeand long stability, while reducing maintenance and cost of ownership. Reliability and durability are guaranteed with NEMA 4x and IP67 compliance.
The durable epoxy paint maximizes chemical resistance; however, for maximum protection in marine environments where salt spray and semi immersion are common, a stainless steel housing is available.
Accuracy
The YTA310 enables advanced linearization of 20 types of industrial temperature sensors and input signals. Utilizing a selected high grade 16bit A/D converter allows the YTA310 to achieve a performance of ±0.05% of calibrated span accuracy.
Stability
The YTA310's stability is inherited from its meticulous product design and development philosophy. Containing a precision internal reference, YTA310 can detect and automatically correct for any instability, delivery a 5 year stability guarantee.
Sensor Matching
The Yokogawa YTA310 uses the IEC751 standard to define the relationship between resistance and temperature for RTD sensors. This relationship is referred to as a Standard Curve. Sensor manufacturers use this same standard, but, because of construction process, each sensor has a unique temperature / resistance relationship. This is referred to as the Real RTD Curve. (The Real RTD Curve falls within the tolerance band of IEC751 standard) In the 1920's, Hugh Longbourne Callendar and M.S. Van Dusen developed a set of coefficients that would modify the Standard Curve to match the Real RTD Curve; thus, removing the error generated by the difference between the two curves. Yokogawa's YTA310 with the CM1 option can accept these coefficients to adjust the Standard Curve to match the Real RTD Curve of the sensor; eliminating this error improves the accuracy of the YTA310 / Sensor system.

Applications:
Caustic soda and hydrochloric acid, produced in electrolyzer plants, are fundamental materials used in varieties of industries; chemicals, pharmaceuticals, petrol-chemicals, pulp and papers, etc. Profit is the result of the effective production with minimized running / maintenance cost. Proper control of the process brings you stabilized quality of products with the vast operational profit.
Steam is still one of the most popular methods of providing an energy source to a process and its associated operations. The more accurate and reliable measurements that are made, the more informed decisions can be taken that affect costs and product quality.
