Scope of Application:

The 3051 differential pressure transmitter is a commonly used industrial measuring instrument for measuring pressure differentials in fluid media. It employs advanced sensing technology and microprocessor control to accurately measure differential pressure in liquid, gas, or steam media and convert it into standard electrical signals.

It finds wide application in various industrial self-control environments, including water conservancy and hydropower, railway transportation, intelligent buildings, production control, aerospace, petrochemicals, oil wells, power generation, ships, machine tools, pipelines, medical, food, and many other industries.

Highlight One: Powerful Data Processing Capability

The 3051 differential pressure transmitter uses a sixteen-bit microcontroller to process 16-bit data in one go. This not only provides powerful functionality but also ensures faster processing speed, fully meeting the requirements of modern industrial fields for high accuracy, reliability, and stability. Moreover, the larger memory addressing space of the sixteen-bit microcontroller allows the transmitter to access more memory locations, making it competitive in terms of cost and power consumption.

The design of the 3051 differential pressure transmitter emphasizes reliability and stability. By employing advanced single-chip technology and sensor digital conversion technology, combined with carefully designed circuits and software, the transmitter can work stably and reliably in various harsh industrial environments.

Highlight Two: Temperature and Pressure Compensation

The 3051 differential pressure transmitter incorporates built-in temperature and pressure sensors to continuously monitor the changes in environmental temperature and pressure in real-time and automatically compensate accordingly. This feature improves measurement accuracy and stability by compensating for the effects of temperature on the sensor, effectively addressing the issue of sensor temperature drift.

The 3051 series differential pressure transmitters are intelligent digital instruments controlled by microprocessors, offering additional functionality and digital compensation capabilities. These intelligent transmitters can respond to proprietary characteristic information related to pressure and temperature inputs, automatically compensating for temperature effects, providing reliable support for industrial automation control.

Highlight Three: Support for RS485 and HART Communication

The 3051 differential pressure transmitter supports communication protocols such as RS485 and HART modules, enhancing its integration capabilities with other devices and systems and providing users with more choices and flexibility.

With the RS485 module, the 3051 differential pressure transmitter can form a distributed system with multiple devices, enabling centralized data acquisition, management, and control. This is particularly important for large-scale industrial automation systems, significantly improving system reliability and stability.

The HART module is an open communication protocol for high-speed communication channels to remotely address sensors. It superimposes digital signals on the low-frequency 4-20mA analog signals using FSK frequency shift keying, enabling bi-directional communication without affecting the normal transmission of analog signals. The HART protocol allows for status monitoring, device configuration, calibration of process variable values, fault diagnosis, system configuration, and parameter settings for field devices. It has become a global communication standard for intelligent instruments.

Highlight Four: Full Isolation Circuit Technology

The 3051 differential pressure transmitter effectively isolates and suppresses electromagnetic interference signals through advanced circuit design and signal processing technology, ensuring measurement data accuracy and stability. In practical applications, the zero point of the transmitter may drift due to environmental factors such as temperature and pressure variations. However, the 3051 differential pressure transmitter features a built-in zero stability tracking system that cancontinuously track and compensate for zero point drift, ensuring accurate and reliable measurements over time.

In summary, the YD-3051 digital intelligent differential pressure transmitter is a high-performance instrument that combines advanced sensor technology, microprocessor control, and digital conversion technology. It offers powerful data processing capabilities, temperature and pressure compensation, support for RS485 and HART communication protocols, and full isolation circuit technology. With its wide range of applications and intelligent features, the YD-3051 transmitter is an excellent choice for accurate and reliable pressure measurement in various industrial settings.
