YURA3051DP Intelligent differential pressure transmitter
Application: Petrol oil, chemical industry, electrical power, paper making, iron and steel, coal gas etc.
Product principle
Intelligent pressure/differential pressure transmitter in question boasts a cutting-edge design. At its core, it features a world-leading technology that utilizes high-precision silicon pressure and differential pressure sensors along with an advanced packaging process. These sensors are crafted from single crystal silicon and are strategically positioned at the top of the metal body, ensuring a significant distance from the medium’s contact surface. This arrangement achieves both mechanical and thermal isolation, enhancing precision.
Furthermore, the transmitter incorporates glass sintered sensor leads, which provide robust electrical insulation within the metal matrix. This not only strengthens the electronic circuits but also equips the device to withstand transient voltage fluctuations effectively.
In terms of accuracy, this transmitter achieves a platinum-grade precision of ±0.05%, even under one-way overvoltage conditions of up to 25MPa. Its static pressure performance is equally impressive, with an optimal control of static pressure error within ±0.05% per 10MPa. Additionally, it exhibits minimal temperature-related response changes, which are optimally controllable, with a variance of just ±0.04% per 10K.
Features and advantages
Advanced monocrystalline silicon differential pressure sensor: This type of sensor uses a silicon diaphragm to measure the difference in pressure between two points. Silicon is a very strong and lightweight material, making it ideal for use in pressure sensors.
Wide pressure range covering -0.1～3MPa: This sensor can measure pressure from -0.1 to 3 MPa. This makes it a versatile sensor that can be used in a variety of applications.
2-wire mode, 4～20mA analog output, HART® protocol digital communication: This sensor can be configured to output data in a variety of ways, including 2-wire mode, 4～20mA analog output, and HART® protocol digital communication. 2-wire mode is the simplest and most cost-effective way to transmit data, while 4～20mA analog output is more versatile and can be used over longer distances. HART® protocol digital communication provides the most flexibility and can be used to transmit additional information about the sensor, such as its calibration status and temperature.
Intelligent LCD gauge with backlight: This sensor has an intelligent LCD gauge with backlight that displays the current pressure reading. The backlight makes it easy to read the gauge in low-light conditions.
With both remote transmission and local zero and pressure range adjustment: This sensor can be configured to transmit data remotely or to allow for local zero and pressure range adjustment. Remote transmission is useful for applications where the sensor is in a difficult-to-reach location. Local zero and pressure range adjustment is useful for fine-tuning the sensor’s output.
Complete varieties, high accuracy, good stability: This sensor is available in a variety of configurations to meet the needs of different applications. It also has high accuracy and good stability, making it a reliable sensor for long-term use.
Isolation ex-proof housing structure, strong resistance to frequency conversion interference: The sensor’s isolation ex-proof housing structure protects it from electrical interference and moisture. This makes it a reliable sensor for use in harsh environments.
High static pressure, high overpressure protection: The sensor has high static pressure and high overpressure protection. This means that it can withstand high pressures without being damaged.
Lightning protection circuit design: The sensor has a lightning protection circuit design. This design helps to protect the sensor from damage caused by lightning strikes.
Functional Parameters
Range limit: The range limit can be adjusted arbitrarily within the upper and lower limits of the measuring range. It is recommended to choose a quantum code with the lowest possible quantum ratio to optimize performance.
Zero-point setting: The zero point and range can be adjusted to any value within the measuring range in the table, as long as the standard range > the minimum range.
Effect of installation location: If the installation position changes perpendicular to the diaphragm surface, it will not cause zero drift effect. If the installation position and the diaphragm surface change by more than 90°, the zero-position effect within the range of <0.4Kpa will occur and the zero adjustment can be adjusted and corrected without range effect.
Output: The output is 2 wire 4-20mA compliant with NAMUR NE43 specification with a selectable liner of square root output for superimposed digital signal (HART protocol).
Output signal limit: The output signal limit is I min.=3.9mA, Imax =21.0mA.
Fault warning: If a sensor or circuit fails, the automatic diagnostics function output 3.9mA or 21.0mA.
Alarm current: The alarm current is Low Alarm Mode (Min.) 3.9mA and High report mode (maximum): 21mA. The alarm current default settings are High report mode.
Response time: The damping constant of the amplifier component is 0.1sec; the sensor time constant is 0.1-1.6sec depending on the range and span ratio. Additional adjustable time constants are 0-100sec.
Warm-up time: The warm-up time is <15sec.
