The 2051C Differential and Gauge Pressure Transmitter focuses on incredible accuracy in pressure, flow, and level applications. This transmitter features various ranges, stability, and accuracy options to ensure the most beneficial user experience.

Advantages

Applications

High Measurement Accuracy: It offers a high - level reference accuracy of 0.075%, and an optional 0.065% enhanced accuracy for applications requiring extremely precise measurements.
Good Stability: With a two - year stability of 0.10% and an optional five - year stability, it can provide reliable measurement results over a long period, reducing the frequency of calibration and maintenance.
Wide Rangeability: The 100:1 rangeability allows the transmitter to cover a wide range of pressure values, reducing the need for multiple transmitters with different ranges, which is convenient for users to use and manage in different application scenarios.
Versatile Platform Design: The coplanar platform design enables the integration of primary elements, manifolds, and diaphragm seal solutions, providing flexible installation options and reducing installation and maintenance costs.
Rich Communication Protocols: It supports multiple communication protocols such as 4 - 20 mA HART, Foundation Fieldbus, and 1 - 5 VDC HART low power, enabling easy integration with different control systems2.
Strong Compatibility: The materials of the process - wetted parts, 316L stainless steel and Hastelloy C - 276, are compatible with a variety of media, suitable for use in harsh environments.
Comprehensive Diagnostics: It has comprehensive diagnostic capabilities, which can monitor the operating status of the transmitter in real - time, facilitating timely troubleshooting and maintenance, and improving the reliability and availability of the system.

Flow Measurement: In flow measurement systems, it is used in combination with primary flow elements such as orifice plates and Venturi tubes. By measuring the differential pressure across the primary element, the flow rate of fluids in pipelines can be accurately calculated, which is applicable to the measurement of gas, liquid, and steam flow in industries such as petroleum, chemical, and power.
Level Measurement: It can be used for liquid level measurement in tanks and vessels. By installing the transmitter at the bottom of the tank and using the hydrostatic pressure principle, the liquid level height is converted into a differential pressure signal for accurate measurement. It is widely used in the storage and transportation of various liquids in industries such as chemical, food, and beverage.
Industrial Process Pressure Monitoring: In various industrial processes, such as the chemical, oil and gas, power generation, and food and beverage industries, it is used to monitor the pressure difference between different points in the process to ensure the normal operation of the process and the safety of equipment. For example, it is used to monitor the differential pressure across filters to detect blockages, and to monitor the pressure difference across heat exchangers and reactors to detect abnormal pressure changes.
Food and Beverage Industry: In the food and beverage industry, it is used to monitor the flow of liquids in pipelines, such as the flow of milk, juice, and other liquids, to control the proportion and ensure the quality and stability of products. At the same time, it can also be used for the liquid level measurement of storage tanks to help manage inventory and production processes.
